We study the effects of the Coulomb interaction in the one dimensional Kondo lattice model on
the phase diagram, the static magnetic susceptibility and electron spin relaxation. We show that onsite C...

We theoretically describe the spin excitation spectrum of a two dimensional electron gas embedded in a quantum well with localized magnetic impurities. Compared to the previous work,
we introduce equ...

We show that edge states similar to those known for topological insulators exist in two-dimensional electron system with one-band spectrum in the presence of heterogeneous spin-orbit interaction (SOI)...

We report a transport study of ultrathin Bi2Se3 topological insulators with thickness from
one quintuple layer to six quintuple layers grown by molecular beam epitaxy. At low
temperatures, the film ...
