We examine the SU(2) Kondo Lattice Model, for simple cubic lattices with various magnitudes of the localized spins j and numbers of conduction electrons, nc. For j=1/2, the system undergoes transitions from the paramagnetic to magnetically ordered st

We study the single-band Hubbard model under the action of an external magnetic field using the cumulant Green's functions method (CGFM). The starting point of the method is to diagonalize a cluster containing N correlated sites (seed) and employ the

The proposed topological Kondo insulator SmB$_{6}$ hosts a bulk Kondo hybridization gap that stems from strong electronic correlations and a metallic surface state whose effective mass remains disputed. Thermopower and scanning tunneling spectroscopy

There have been a number of reports of experimental observations of a field-dependent enhancement of the Rashba spin-orbit splitting in surface states. We show that strong Coulomb correlations lead to an enhancement of the spin-orbit coupling which i

We examine the conditions required to produce a combined spin and orbital density wave state such as that which has been proposed to describe the “Hidden Order” phase of URu2Si2. By using an idealized tight-binding model with only nearest-neighbo
