Nonperturbative master equation solution of central spin dephasing dynamics
Edwin Barnes, Łukasz Cywiński, S. Das Sarma
We solve the long-standing central spin problem for a general set of inhomogeneous bath couplings and a large class of initial bath states. We compute the time evolution of the coh…

PbTe/PbSnTe heterostructures as analogs of topological insulators
Ryszard Buczko, Łukasz Cywiński
We investigate theoretically the PbTe/PbSnTe heterostructure grown in [111] direction, specifically a quantum wall (potential step of width d) of PbTe embedded in Pb_{1-x}Sn_{x}Te.…
