We demonstrate that the well-known expression for the charge magnetization of a sample with a non-zero Berry curvature can be obtained by demanding that the Einstein relation holds for the electric transport current. We extend this formalism to the transport energy current and show that the energy magnetization must satisfy a particular condition. We provide a physical interpretation of this condition and relate the energy magnetization to circulating energy currents due to chiral edge states…

Berry-phase effect in anomalous thermoelectric transport.

TLDR
A finite-temperature formula for the orbital magnetization is derived, which enables to provide an explicit expression for the off-diagonal thermoelectric conductivity, to establish the Mott relation between the anomalous Nernst and Hall effects, and to reaffirm the Onsager relations between reciprocal thermoelectedric conductivities.

Berry Phase Effects in Dipole Density and the Mott Relation.

TLDR
The dipole density of a physical quantity emerges and plays a vital role, which contains not only the statistical sum of the dipole moment of θ[over ^] but also a Berry phase correction.

Berry curvature induced thermopower in type-I and type-II Weyl semimetals

Berry curvature acts analogously to a magnetic field in the momentum space, and it modifies the flow of charge carriers and entropy. This induces several intriguing magnetoelectric and magnetothermal

THERMOELECTRIC RESPONSE OF AN INTERACTING TWO-DIMENSIONAL ELECTRON GAS IN A QUANTIZING MAGNETIC FIELD

We present a discussion of the linear thermoelectric response of an interacting electron gas in a quantizing magnetic field. Boundary currents can carry a significant fraction of the net current

TLDR
Both theories of polarization and magnetization are reviewed on a uniform ground in a density functional theory (DFT) framework, pointing out analogies and differences.

Role of Berry curvature in the generation of spin currents in Rashba systems

We study the background (equilibrium), linear and nonlinear spin currents in 2D Rashba spin-orbit coupled systems with Zeeman splitting and in 3D noncentrosymmetric metals using modified spin current

Thermoelectric response of spin polarization in Rashba spintronic systems

Motivated by the recent discovery of a strongly spin–orbit-coupled two-dimensional (2D) electron gas near the surface of Rashba semiconductors BiTeX (X = Cl, Br, I), we calculate the thermoelectric

Quantum Nonlinear Hall Effect Induced by Berry Curvature Dipole in Time-Reversal Invariant Materials.

TLDR
It is demonstrated that Hall-like currents can occur in second-order response to external electric fields in a wide class of time-reversal invariant and inversion breaking materials, at both zero and twice the driving frequency.
