Full magnetoelectric response of Cr2O3 from first principles
Andrei Malashevich, Sinisa Coh, Ivo Souza +1
The linear magnetoelectric response of Cr2O3 at zero temperature is calculated from first principles by tracking the change in magnetization under a macroscopic electric field. Bot…
Nonadiabatic wavepacket dynamics: k-space formulation
J. M. Pruneda, Ivo Souza
The time evolution of wavepackets in crystals in the presence of a homogeneous electric field is formulated in k-space in a numerically tractable form. The dynamics is governed by…
Dichroic f-sum rule and the orbital magnetization of crystals
Ivo Souza, David Vanderbilt
We consider the magnetic circular dichroism spectrum of a crystal with broken time-reversal symmetry in the electric-dipole approximation. Using the Kubo-Greenwood formula for the…
Spectral and Fermi surface properties from Wannier interpolation
Jonathan R. Yates, Xinjie Wang, David Vanderbilt +1
We present an efficient first-principles approach for calculating Fermi surface averages and spectral properties of solids, and use it to compute the low-field Hall coefficient of…
Dynamics of Berry-phase polarization in time-dependent electric fields
Ivo Souza, Jorge Iniguez, David Vanderbilt
We consider the flow of polarization current J(t)=dP/dt produced by a homogeneous electric field E(t) or by rapidly varying some other parameter in the Hamiltonian of a solid. For…
