The objective of this work is to describe the tunnel electron current in single-barrier magnetic tunnel junctions within an approach that goes beyond the single-band transport model. We propose a ballistic multichannel electron transport model that ca . . .

Topological insulators (TIs) are a new quantum state of matter discovered recently, which are characterized by unconventional bulk topological invariants. Proposals for practical applications of the TIs are mostly based upon their metallic surface or . . .

We study exchange coupling due to the interelectron Coulomb interaction between two ferromagnetic grains embedded into an insulating matrix. This contribution to the exchange interaction complements the contribution due to virtual electron hopping bet . . .

In this paper we use a three-dimensional Pauli master equation to investigate the charge carrier mobility of a two-phase system which can mimic donor-acceptor and amorphous-crystalline bulk heterojunctions. By taking the energetic disorder of each pha . . .

The self-consistent embedding theory provides a rigorous framework for quantum/molecular mechanics simulations of materials. By using crystalline aluminum as an example, we present a critical analysis on the accuracy of the embedding theory, focusing . . .

A one-dimensional electron model with parameters modulated adiabatically in closed cycles is proposed which can continuously pump spin to leads. By defining the spin-polarized Wannier functions, we reveal that the spin pumping is protected by the spin . . .

The thermoelectric transport properties of elemental tellurium are investigated by density functional theory combined with the Boltzmann transport equation in the rigid band approximation. We find that the thermoelectric transport properties parallel . . .

By using Gutzwiller projected fermionic wave functions and variational Monte Carlo technique, we study the spin-1/2 Heisenberg model with the first-neighbor (J1), second-neighbor (J2), and additional scalar chiral interaction JχSi⋅(Sj×Sk) on the trian . . .

A method for calculating hydrodynamic added mass within the framework of time-dependent bosonic density functional theory (DFT) for superfluid 4He is developed. As a calibration of the model, it is shown to reproduce the classical hydrodynamic limit f . . .
