Axion electrodynamics in topological materials

A Sekine, K Nomura - Journal of Applied Physics, 2021 - pubs.aip.org
One of the intriguing properties characteristic to three-dimensional topological materials is
the topological magnetoelectric phenomena arising from a topological term called the θ …

A tale of analogies: A review on gravitomagnetic effects, rotating sources, observers and all that

ML Ruggiero, D Astesiano - Journal of Physics Communications, 2023 - iopscience.iop.org
Gravitoelectromagnetic analogies are somewhat ubiquitous in General Relativity, and they
are often used to explain peculiar effects of Einstein's theory of gravity in terms of familiar …

Torsional Landau levels and geometric anomalies in condensed matter Weyl systems

S Laurila, J Nissinen - Physical Review B, 2020 - APS
We consider the role of coordinate-dependent Fermi velocities, equivalent to effective tetrad
(or vierbein) frame fields characterizing momentum space geometry, and torsional Landau …

Chiral torsional effect with finite temperature, density, and curvature

Z Qiu, S Imaki - Physical Review D, 2020 - APS
We scrutinize the novel chiral transport phenomenon driven by spacetime torsion, namely,
the chiral torsional effect (CTE). We calculate the torsion-induced chiral currents with finite …

Quantum kinetic theory of thermoelectric and thermal transport in a magnetic field

A Sekine, N Nagaosa - Physical Review B, 2020 - APS
We present a general quantum kinetic theory that accounts for the interplay between a
temperature gradient, momentum-space Berry curvatures of Bloch electrons, and Bloch …

Quaternion algebra on 4d superfluid quantum space-time: Gravitomagnetism

VI Sbitnev - Foundations of Physics, 2019 - Springer
Gravitomagnetic equations result from applying quaternionic differential operators to the
energy–momentum tensor. These equations are similar to the Maxwell's EM equations. Both …

Gravitational waves propagation in nondynamical Chern–Simons gravity

A Martín-Ruiz, LF Urrutia - International Journal of Modern Physics …, 2017 - World Scientific
We investigate the propagation of gravitational waves in linearized Chern–Simons (CS)
modified gravity by considering two nondynamical models for the coupling field 𝜃:(i) a …

Topological magnetoelectric pump in three dimensions

T Fukui, T Fujiwara - Physical Review B, 2017 - APS
We study the topological pump for a lattice fermion model mainly in three spatial
dimensions. We first calculate the U (1) current density for the Dirac model defined in …
