Constraining the loop quantum gravity parameter space from phenomenology
Physics Letters B, 2018 Development of quantum gravity theories rarely takes inputs from experimental physics. In this letter, we take a small step towards correcting this by establishing a paradigm for incorporating putative quantum corrections, arising from canonical quantum ...

Rock Physics of the Critical Zone: Models, Inversion, and Interpretation
Reviews of Geophysics, Volume 64, Issue 2, June 2026.Abstract Rock physics models link geophysical measurements with subsurface petrophysical properties, such as porosity, mineral composition, and fluid saturation. While originally developed for hydrocarbon exploration, these models are increasingly applied in the near surface for quantitative interpretation of geophysical data.

Phase transition in loop quantum gravity [PDF]
Physical Review D, 2016 We point out that with a specific counting of states loop quantum gravity implies that black holes perform a phase transition at a certain characteristic temperature $T_C$. In this phase transition the punctures of the spin network on the stretched horizon of the black hole jump, in effect, from the vacuum to the excited states.

Quantization of Midisuperspace Models
Living Reviews in Relativity, 2010 We give a comprehensive review of the quantization of midisuperspace models. Though the main focus of the paper is on quantum aspects, we also provide an introduction to several classical points related to the definition of these models.

Synthesis, Crystal Structure, and Optoelectronic Properties of [(n‐/tert‐C4H9)S(CH3)2]PbI3
European Journal of Inorganic Chemistry, Volume 29, Issue 15, 20 May 2026.Reaction of two isomers of butyldimethylsulfonium cation with PbI2 using solid‐state and solution methods yielded the corresponding organic/inorganic hybrid compounds with high humidity tolerance and 1D crystal structures of [n‐C4H9S(CH3)2]PbI3 and [tert‐C4H9S(CH3)2]PbI3.

Loop Quantum Gravity Vacuum with Nondegenerate Geometry
Symmetry, Integrability and Geometry: Methods and Applications, 2012 In loop quantum gravity, states of the gravitational field turn out to be excitations over a vacuum state that is sharply peaked on a degenerate spatial geometry.

Massive particles tunneling from quantum Oppenheimer-Snyder black holes and black hole entropy
Physics Letters BIn this paper, we investigate the tunneling process of massive scalar particles from a quantum Oppenheimer-Snyder black hole using the tunneling approach proposed by Parikh and Wilczek.

Newtonian gravity in loop quantum gravity
, 2010 We apply a recent argument of Verlinde to loop quantum gravity, to conclude that Newton's law of gravity emerges in an appropriate limit and setting. This is possible because the relationship between area and entropy is realized in loop quantum gravity when boundaries are imposed on a quantum spacetime.

Quantum General Invariance and Loop Gravity
Foundations of Physics, 2001 A quantum physical projector is proposed for generally covariant theories which are derivable from a Lagrangian. The projector is the quantum analogue of the integral over the generators of finite one-parameter subgroups of the gauge symmetry transformations which are connected to the identity.

Sine-dilaton gravity vs double-scaled SYK: exploring one-loop quantum corrections
Journal of High Energy PhysicsWe provide non-trivial checks of the recently proposed duality between double-scaled SYK and a 2d dilaton gravity model with sine potential, studying the path integral at one-loop level.
