Established forms of electromagnetic coupling are usually conservative (in insulators) or dissipative (in metals and semiconductors). Here, we point out the possibility of nondissipative electric driving of magnetization dynamics, if the valence elec

Under the Born-Oppenheimer approximation, the electronic ground state evolves adiabatically and can accumulate geometrical phases characterized by the molecular Berry curvature. In this work, we study the effect of the molecular Berry curvature on th

A semiclassical theory for the orbital magnetization due to adiabatic evolutions of Bloch electronic states is proposed. It renders a unified theory for the periodic-evolution pumped orbital magnetization and the orbital magnetoelectric response in i

At present, tungsten oxide is mainly produced by atmospheric decomposition of ammonium paratungstate (APT), which usually causes uneven particle size and morphology. In this paper, non-agglomerated tungsten oxide was prepared by vacuum pyrolysis (vac

In model studies of the spin/anomalous Hall effect, effective Hamiltonians often serve as the starting point. However, a complete effective quantum theory contains not only the effective Hamiltonian but also the relation linking the physical observab

To give a general description of the influences of electric fields or currents on magnetization dynamics, we developed a semiclassical theory for the magnetization implicitly coupled to electronic degrees of freedom. In the absence of electric fields

The conserved bulk spin current [Shi et al., Phys. Rev. Lett. 96, 076604 (2006)], defined as the time derivative of the spin displacement operator, ensures automatically the Onsager relation between the spin Hall effect (SHE) and the inverse SHE. Her

We provide a unified semiclassical theory for thermoelectric responses of any observable represented by an operator $\hat{\boldsymbol{\theta}}$ that is well-defined in periodic crystals. The Einstein and Mott relations are established generally, in t

The thermal conductivity of free-standing silicon nanowires (SiNWs) with diameters from 1–3 nm has been studied by using the one-dimensional Boltzmann’s transport equation. Our model explicitly accounts for the Umklapp scattering process and elec
