Studies of the electromagnetic response of various classes of correlated electron materials
including transition-metal oxides, organic and molecular conductors, intermetallic …

Recent experiments have proven that the quasiparticles in graphene obey a Dirac equation.
Here we show that microwaves are an excellent probe of their unusual dynamics. When the …

Linear response theory plays a prominent role in various fields of physics and provides us
with extensive information about the thermodynamics and dynamics of quantum and …

We compare calculations based on the dynamical mean-field theory of the Hubbard model
with the infrared spectral weight W (Ω, T) of La 2-x Sr x CuO 4 and other cuprates. Without …

We begin with an overview of the experimental results for the temperature and doping
dependences of the optical-conductivity spectral weight in cuprate superconductors across …

We develop a computational approach for calculating the optical conductivity in the
augmented plane-wave basis set of wien2k and apply it for thoroughly comparing the full …

We examine the redistribution of the in-plane optical spectral weight in the normal and
superconducting state in trilayer Bi 2 Sr 2 Ca 2 Cu 3 O 10 (Bi2223) near optimal doping (T …

We study the Hall conductivity in single-layer gapped Dirac fermion materials including
coupling to a phonon field, which not only modifies the quasiparticle dynamics through the …

We consider theoretically the effects of an applied uniform magnetic field on the magnetic
spectrum of anisotropic two-dimensional and Dzyaloshinskii-Moriya layered quantum …

Pb 0.77 Sn 0.23 Se is a promising thermoelectric alloy that exhibits a temperature
dependent band inversion below 300 K. Recent work has shown that this band inversion …
