Mott transition in the Hubbard model away from particle-hole symmetry

We solve the dynamical mean-field theory equations for the Hubbard model away from the particle-hole-symmetric case using the density matrix renormalization group method. We focus our study on the region of strong interactions and finite doping where two solutions coexist. We obtain precise predictions for the boundaries of the coexistence region. In addition, we demonstrate the capabilities of this precise method by obtaining the frequency-dependent optical conductivity spectra.

Direct determination of the crystal field parameters of Dy, Er, and Yb impurities in the skutterudite compound CeFe 4 P 12 by electron spin resonance

Despite extensive research on the skutterudites for the last decade, their electric crystalline field ground state is still a matter of controversy. We show that electron spin resonance (ESR) measurements can determine the full set of crystal field parameters (CFPs) for the
