Advances in Topological Thermoelectrics: Harnessing Quantum Materials for Energy Applications
Topological materials offer a novel platform for thermoelectric energy conversion through unique band features, including band inversion, linear Dirac bands, surface states, and Berry curvature. These quantum characteristics enable enhanced longitudinal and transverse thermoelectric effects, establishing topological thermoelectrics as a promising ...

Tests of Lorentz Symmetry in Single Beta Decay
Low-energy experiments studying single beta decay can serve as sensitive probes of Lorentz invariance that can complement interferometric searches for deviations from this spacetime symmetry.

Testing Lorentz invariance with neutrino bursts from supernova neutronization
Quantum-gravity (QG) effects might generate Lorentz invariance violation by the interaction of energetic particles with the foamy structure of the space-time. As a consequence, particles may not travel at the universal speed of light.

Momentum-resolved probing of Lorentz-violating dispersion relations via Unruh-DeWitt detector
Inspired by quantum gravity frameworks predicting Planck-scale deviations from Lorentz invariance, we probe Lorentz symmetry violation via modified dispersion relations ω|k|.

Testing Lorentz invariance in β decay
In theories aiming to unify the Standard Model with gravity, Lorentz invariance may be broken. Although Lorentz symmetry appears to hold well, few experiments have been performed that consider its violation in the weak interaction.

Constraints on Lorentz Invariance Violation using INTEGRAL/IBIS observations of GRB041219A [PDF]
One of the experimental tests of Lorentz invariance violation is to measure the helicity dependence of the propagation velocity of photons originating in distant cosmological obejcts.

Abstract The unification of conformal and fuzzy gravities with internal interactions is based on the facts that i) the tangent group of a curved manifold and the manifold itself do not necessarily have the same dimensions and ii) both gravitational theories considered here have been formulated in a gauge theoretic way.

Spin‐Polarized Antiferromagnets for Spintronics
This review highlights recent advances in anomalous and spin transport phenomena in spin‐polarized antiferromagnets. Key effects—including the anomalous Hall, Nernst, and magneto‐optical effects—are discussed across various antiferromagnetic platforms.

No CPT Violation from Tilted Brane in Neutral Meson--Antimeson Systems [PDF]
Tilted brane in theories with large compact extra dimensions leads to spontaneous symmetry breaking of the Lorentz and rotational invariance in four dimensions, as shown by Dvali and Shifman.

Considering Late-Time Acceleration in Some Cosmological Models
We study two cosmological models: a nonminimally coupled scalar field on brane world model and a minimally coupled scalar field on Lorentz invariance violation model. We compare some cosmological results in these scenarios.
