Quantum Gravitational Non-Singular Tunneling Wavefunction Proposal
Physical Sciences Forum, 2023 It has recently been shown that the tunneling wavefunction proposal is consistent with loop quantum geometry corrections, including both holonomy and inverse scale factor corrections, in the gravitational part of a spatially closed isotropic model with a

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT
Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2048-2072, August 2026.Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

Starobinsky potential and power suppression in hybrid loop quantum cosmology
Physics Letters BWe study the effect on the primordial tensor power spectrum of varying the number of e-folds during slow-roll inflation in Loop Quantum Cosmology with a Starobinsky potential. Using the hybrid quantization approach, we derive the effective mass governing

Loop quantum cosmology with a non-commutative quantum deformed photon gas
European Physical Journal C: Particles and Fields, 2018 The non-commutativity of the space-time had important implications for the very early Universe, when its size was of the order of the Planck length. An important implication of this effect is the deformation of the standard dispersion relation of special

Guiding and Manipulating Light Fields in Microstructured Liquid Crystals
Advanced Physics Research, Volume 5, Issue 7, July 2026.This review summarizes recent advances in guided‐wave optics enabled by microstructured liquid crystal (LC) devices, covering their fundamental material properties, key degree of freedom for dynamic light field manipulations. The advances of linear guided‐wave optics, nonlinear‐optics with spatial optical solitons, and microlasers in LC‐based devices ...

Phase space quantization and Loop Quantum Cosmology: a Wigner function for the Bohr-compactified real line [PDF]
, 2008 We give a definition for the Wigner function for quantum mechanics on the Bohr compactification of the real line and prove a number of simple consequences of this definition. We then discuss how this formalism can be applied to loop quantum cosmology. As

New Hamiltonian constraint operator for loop quantum gravity
Physics Letters B, 2015 A new symmetric Hamiltonian constraint operator is proposed for loop quantum gravity, which is well defined in the Hilbert space of diffeomorphism invariant states up to non-planar vertices with valence higher than three. It inherits the advantage of the

Magnetic properties of geraisites, the first tektite strewn field identified in Brazil
Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1163-1178, July 2026.Abstract Geraisites are a newly recognized class of tektite from Brazil. They occur as centimeter‐sized, elongated to subspherical bodies scattered across surface gravel and shallow subsurface layers within a ~90‐km‐long strewn field extending between the municipalities of São João do Paraíso and Curral de Dentro, near the border between the states of ...
