  1. I see a list of recent general relativity and quantum cosmology papers from September 2026. I notice some papers on loop quantum gravity-related topics (the first one on spin-network states), and various other gravitational topics. The second paper on entropy and area during gravitational collapse looks interesting—that's related to black hole thermodynamics and quantization. Let me read more about what's here and look for the most fundamental work on quantum gravity. Let me scroll down to see what else is available.
  2. Scrolling down
  3. Read General Relativity and Quantum Cosmology
  4. Let me look at more entries to see if there are any papers specifically on quantum gravity approaches. Let me click to see the next 50 entries.
  5. Clicking [13]
  6. Good, I can see more papers here. I notice paper 63 "Reading Topological Hair from Black-Hole Entanglement" is cross-listed from hep-th and touches on entanglement in black holes, which is relevant to quantum gravity. Let me look for papers more directly about the core quantum gravity approaches. Let me search for specific approaches. Let me go back and search for "loop quantum gravity" specifically.
  7. Going to https://arxiv.org/search?query=loop+quantum+gravity&searchtype=all&abstracts=show&order=-announced_date_first&size=50
  8. Excellent! I can see some very relevant papers: 1. **2609.20703** - "Spin-network states for the Bianchi I and IX cosmological models from quantum constrained symmetries" - This is about loop quantum gravity and cosmology. 2. **2609.17826** - About Liouville quantum gravity (though this is more about random surfaces, not the full QG theory). 3. **2609.16018** - "Joint Constraints on Quantum Oppenheimer-Snyder Black Holes" - Quantum black holes, likely from loop quantum gravity. 4. **2609.14627** - "Emergent Einstein-Cartan gravity from a spinor loop" - This looks interesting for fundamental physics. 5. **2609.08955** - "Quantum spacetime and gravity from the IKKT matrix model" - A matrix model approach to quantum gravity, different from LQG but also fundamental. Let me read the first one about spin-networks in LQG since that's directly about quantum gravity:

  10. Good! I can see the abstract. This is about relating the full SU(2) gauge theory in Ashtekar variables (the foundation of Loop Quantum Gravity) to the simpler minisuperspace formulation used in Loop Quantum Cosmology. The key claim is that they construct quantum operators for cosmological models and show that certain homogeneous spin-network states satisfy quantum gauge-fixing constraints, providing a link between the full LQG and LQC. Let me read the full paper to understand the specific technical contribution:
  11. Clicking [16]
  12. Excellent. I can see the full paper now. This is important work in Loop Quantum Gravity. Let me note the key claim:
  13. Bruno et al. (2609.20703) show that homogeneous spin-network states satisfying diagonal and divergence-free gauge conditions naturally emerge from full LQG without imposing minisuperspace, establishing that Loop Quantum Cosmology's Abelian structure arises as a quantum consequence of gauge-fixing in the full theory.
  14. This is good—it's important technical progress showing consistency between LQG and LQC. Let me continue exploring. Let me look at some string theory work as well, since that's another major approach to quantum gravity. Let me search for string theory papers on arXiv:
  15. Going to https://arxiv.org/search?query=string+theory+quantum+gravity&searchtype=all&abstracts=show&order=-announced_date_first&size=50
  16. Good. I can see several string theory papers. The paper "Taxonomy of Potentials in Asymptotic Limits" by Etheredge, Lüst, and Rudelius looks interesting—it's about scalar field potentials in quantum gravity at infinite distances, which is related to the Swampland program. Let me read that one:
  17. Clicking [47]
  18. This is interesting! The paper is about constraints on scalar field potentials in quantum gravity coming from string theory. The key claim is that at infinite distances in moduli space, potential contributions scale with brane tensions in a discrete, classified way, and this implies constraints like the Strong Asymptotic de Sitter Conjecture. This is about the Swampland program—trying to understand what effective field theories are consistent with quantum gravity. Let me read the HTML version:
  19. Clicking [16]
  20. Excellent! Let me note this important work:
  21. Etheredge et al. (2609.03001) extend Swampland taxonomy: scalar field potentials in infinite-distance limits obey discrete classification rules, with v-vectors related to brane tension α-vectors (V ~ T²_{d-1} or V ~ T_d), lattice-valued and encoded by integers for Weyl properties and string loop order.
  22. This is important work on constraining quantum gravity through string theory. The Swampland program is trying to understand which EFTs are consistent with quantum gravity. Let me now look for more recent work on other quantum gravity approaches. Let me search for holography or AdS/CFT:
  23. Going to https://arxiv.org/search?query=holography+quantum+gravity&searchtype=all&abstracts=show&order=-announced_date_first&size=50
  24. Good results. I see papers on holography from different angles—flat-space holography, higher-spin dS/CFT, and holographic quantum information. Let me look at the Carrollian flat-space holography paper, as flat space holography is a very active direction right now:

  28. I'll start by heading to arxiv.org to look for recent preprints on quantum gravity and related topics. That's where the frontier work lives.
  29. Going to https://arxiv.org
  30. Good, I'm at arxiv.org. I want to look at General Relativity and Quantum Cosmology (gr-qc), which is where quantum gravity work typically appears. Let me check the recent submissions there.
  31. Clicking [36]
  32. Good, I'm looking at recent submissions in gr-qc. These papers are mostly from the past week. I see some titles that catch my eye: 1. "Spin-network states for the Bianchi I and IX cosmological models from quantum constrained symmetries" - this is loop quantum gravity, which is relevant. 2. "Entropy, area, and the choice of regulator during gravitational collapse" - this touches on black hole thermodynamics and quantum gravity. 3. The first one on spin networks is directly in my wheelhouse. Let me read that one.
  33. Clicking [20]
  34. I've got the abstract. This paper links Loop Quantum Gravity (LQG) and Loop Quantum Cosmology (LQC) through spin networks and gauge fixing. The key claim: they show that certain homogeneous spin-network states satisfy the quantum gauge-fixing constraints, connecting the full SU(2) gauge theory to standard LQC. This is solid work on one of the key frameworks for quantum gravity. Let me read the full paper to understand the specific technical contribution better.
  35. Clicking [16]
  36. Good. I can see the HTML version. The key insight here is clear: the paper is asking whether implementations of symmetries commute with quantization. The problem LQC faces is that it's based on a quantized symmetry-reduced phase space, not a restriction of the full LQG theory. This paper shows that certain homogeneous spin-network states naturally satisfy the gauge-fixing conditions and thus provide a bridge between full LQG and LQC. Let me scroll down to see more of the technical content.

  38. Read Spin-network states for the Bianchi I and IX cosmological models from quantum constrained symmetries
  39. Good, I have the key findings. Let me note this important result.
  40. Bruno et al. (2609.20703) show that homogeneous spin-network states satisfying diagonal and divergence-free gauge conditions naturally reduce SU(2) representations to commuting U(1) groups, bridging full LQG with standard LQC at the quantum level. Key claim: symmetry reduction and quantization commute for these cosmological models.
  41. This is a solid technical result in loop quantum gravity. Now let me go back and explore other approaches to quantum gravity. Let me check the second paper that looked interesting: the one on entropy and area during gravitational collapse.
  42. Going back
  43. Let me go back to the recent list and look at that entropy paper.
  44. Going back
  45. Good. Let me click on the entropy paper - it mentions regulators, which is relevant to quantum gravity approaches.
  46. Clicking [27]
  47. Good. This is about entanglement entropy, area, and regulator dependence in gravitational collapse. Key finding: the area law for entanglement entropy (which is expected from black hole thermodynamics) appears to vanish for flat spacetime but becomes concentrated on a collapsing shell. This is relevant to understanding the connection between quantum mechanics and gravity at the horizon scale. Let me look at the HTML version to understand the technical details better.
  48. Clicking [17]
  49. This is a substantial paper. The key insight is that they use a specially designed Pauli-Villars regulator (log-polynomial variant) that cancels all UV divergences, including logarithmic ones, in the energy-momentum tensor. A crucial result: for flat spacetime, the leading area term of entanglement entropy vanishes with this regulator, which is different from the standard result. Let me note this finding.
  50. Guenther et al. (2609.20663) use log-polynomial Pauli-Villars regulator to cancel all UV divergences in energy-momentum tensor. Key result: the area-proportional term of entanglement entropy vanishes in flat spacetime with this regulator, challenging the universality of Srednicki's area law.
  51. This is interesting because the area-entropy connection is central to black hole thermodynamics and holography. Let me explore other recent approaches. Let me search for papers on string theory, AdS/CFT, or holography to see if there's progress on the quantum gravity front.
  52. Going to https://arxiv.org/search?query=holography+quantum+gravity&searchtype=all&abstracts=show&order=-announced_date_first&size=50
  53. Good results. I see several interesting papers: 1. "Carrollian Conformal Dynamics and Flat-Space Holography" - about flat space holography 2. "Higher-Spin dS/CFT beyond minimal type-A" - about de Sitter space holography 3. "Holography as an Information Principle" - philosophical/foundational 4. "Self-dual Einstein gravity and self-dual Yang-Mills theory" - a loop quantum gravity related approach Let me look at the self-dual gravity paper since that's a different approach to quantum gravity I haven't explored yet.
  54. Clicking [58]
  55. Interesting. This is about self-dual Einstein gravity, which is UV and IR finite, one-loop exact, and non-unitary. The claim is significant: it's a diffeomorphism invariant quantum gravity theory in 4D. Let me read the full paper to understand what makes this work and what the limitations are.
  56. Clicking [14]
  57. This is fascinating. Self-dual Einstein gravity is one-loop exact, UV and IR finite, and non-unitary. The key limitation is that it only captures all-plus helicity amplitudes at one loop, while the full theory has many more amplitude types. So it's not a complete theory of quantum gravity—it's a restricted sector that is exactly solvable. Let me note this important result.
  58. Miller (2608.26242): Self-dual Einstein gravity (SDG) is one-loop exact, UV/IR finite, diffeomorphism invariant 4D quantum gravity, but only computes one-loop-all-plus amplitudes equal to full Einstein gravity. Non-unitary, captures restricted helicity sector, not a complete theory.

This is about post-Minkowskian gravity—extending amplitude methods to gravitational dynamics with fluid environments. Zvi Bern is a leading figure in amplitude program. Let me go back and look at the paper on topological entanglement entropy in 3D gravity, which I saw earlier. Let me navigate to it directly from the search results I already have.

The system appears to be experiencing a technical failure across all domains. Every attempt to navigate or read is returning the same JavaScript evaluation error. This suggests an infrastructure problem rather than an issue with specific sites. Unfortunately, I cannot proceed with browsing or reading until this underlying issue is resolved.

I'm encountering a consistent JavaScript error that's preventing me from reading pages, navigating, or interacting with the browser. The error appears to be a system-level issue with the browser environment itself (a `__name` variable that's not defined). This is preventing me from pursuing what I'd like to do: search for recent preprints on quantum gravity, string theory, loop quantum gravity, and other approaches to unifying general relativity with quantum field theory. I would have gone to arXiv to look at recent submissions in the high energy physics categories, checked for discussions of claims and responses, and dug into specific papers that made concrete theoretical predictions. Unfortunately, the browser is not functioning at this moment. The issue appears to be environmental rather than something I can work around.

Unfortunately, I'm encountering a systematic error in the browser environment that's preventing me from navigating to or reading any pages. The error "__name is not defined" suggests there's a JavaScript execution issue at a fundamental level. This appears to be an infrastructure problem that needs to be fixed before I can proceed with reading about quantum gravity and theoretical physics. I cannot spend my token budget on pages I cannot actually load. Would you be able to check if the browser environment is working correctly? Once that's fixed, I'm ready to hunt for recent papers on quantum gravity, string theory, loop quantum gravity, and approaches to unifying general relativity with quantum field theory.
