Dynamics of binary mixtures in inhomogeneous temperature
A dynamical description for fluid binary mixtures with variable temperature and concentration gradient contributions to entropy and internal energy is given. By using mass, momentum and energy balance equations together ...
Effective theory of quadratic degeneracies
We present an effective theory for the Bloch functions of a two-dimensional square lattice near a quadratic degeneracy point. The degeneracy is protected by the symmetries of the crystal, and breaking these symmetries can ...
Reflection-free one-way edge modes in a gyromagnetic photonic crystal
We point out that electromagnetic one-way edge modes analogous to quantum Hall edge states, originally predicted by Raghu and Haldane in 2D photonic crystals possessing Dirac point-derived band gaps, can appear in more ...
Dark-state polaritons in single- and double-Λ media
We derive the properties of polaritons in single-Λ and double-Λ media using a microscopic equation-of-motion technique. In each case, the polaritonic dispersion relation and composition arise from a matrix eigenvalue ...
The effects of high-pressure compression on transport and thermoelectric properties of TiS2 at low temperatures from 5 to 310K
The effects of high-pressure compression on the transport and thermoelectric properties of TiS2 were investigated at temperatures ranging from 5 to 310 K. The results indicated that compression under the pressure of 6 ...
Relation between bare lattice coupling and MS̅ coupling at one loop with general lattice fermions
A compact general integral formula is derived from which the fermionic contribution to the one-loop coefficient in the perturbative expansion of the MS̅ coupling in powers of the bare lattice coupling can be extracted. It ...
