Entropic Forces and Newton’s Gravitation
Entropy, 2020 Our subject of interest here is entropic forces, as re-interpreted by Verlinde with reference to gravitation, that is, by appealing to Verlinde’s conception of an entropic (statistically emergent) gravity advanced in [Physica A 2018, 511, 139].

The Hilbert space of Chern-Simons theory on the cylinder. A Loop Quantum Gravity approach
, 2009 As a laboratory for loop quantum gravity, we consider the canonical quantization of the three-dimensional Chern-Simons theory on a noncompact space with the topology of a cylinder.

Astronomische Nachrichten, Volume 346, Issue 7-8, September 2025.ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Phase transitions and geothermodynamics of black holes in dRGT massive gravity
European Physical Journal C: Particles and Fields, 2019 In this paper, we study the thermodynamics and geothermodynamics of spherical black hole solutions in dRGT massive gravity in a new extended phase space. Inspire by the work of Kastor et al.

Lifting SU(2) Spin Networks to Projected Spin Networks
, 2010 Projected spin network states are the canonical basis of quantum states of geometry for the most recent EPR-FK spinfoam models for quantum gravity. They are functionals of both the Lorentz connection and the time normal field.

Generation of Oil‐In‐Water Emulsion‐Core Sodium Alginate Beads
Macromolecular Chemistry and Physics, Volume 226, Issue 18, September 19, 2025.A core‐shell encapsulation platform is developed by embedding oil‐in‐water emulsions within alginate shells. Optimized formulations with mineral oil, CMC, and non‐ionic surfactants produce uniform spherical beads with tunable core sizes and shell thicknesses.

Towards (3+1) gravity through Drinfel'd doubles with cosmological constant
Physics Letters B, 2015 We present the generalisation to (3+1) dimensions of a quantum deformation of the (2+1) (Anti)-de Sitter and Poincaré Lie algebras that is compatible with the conditions imposed by the Chern–Simons formulation of (2+1) gravity.

Bohmian quantum gravity and cosmology
, 2019 Quantum gravity aims to describe gravity in quantum mechanical terms. How exactly this needs to be done remains an open question. Various proposals have been put on the table, such as canonical quantum gravity, loop quantum gravity, string theory, etc ...

Global and microlocal aspects of Dirac operators: Propagators and Hadamard states
Mathematische Nachrichten, Volume 298, Issue 9, Page 2942-2974, September 2025.Abstract We propose a geometric approach to construct the Cauchy evolution operator for the Lorentzian Dirac operator on Cauchy‐compact globally hyperbolic 4‐manifolds. We realize the Cauchy evolution operator as the sum of two invariantly defined oscillatory integrals—the positive and negative Dirac propagators—global in space and in time, with ...

A Lorentz-Covariant Connection for Canonical Gravity
Symmetry, Integrability and Geometry: Methods and Applications, 2011 We construct a Lorentz-covariant connection in the context of first order canonical gravity with non-vanishing Barbero-Immirzi parameter. To do so, we start with the phase space formulation derived from the canonical analysis of the Holst action in which
