Dynamics of a quantum oscillator strongly and off-resonantly coupled with a two-level system
Titus Sandu
Beyond the rotating-wave approximation, the dynamics of a quantum oscillator interacting strongly and off-resonantly with a two-level system exhibit beatings, whose period equals t…

Ab-initio calculations of spin tunneling through an indirect barrier
Athanasios N Chantis, Titus Sandu, Jialei L Xu
We use a fully relativistic layer Green's functions approach to investigate spin-dependent tunneling through a symmetric indirect band gap barrier like GaAs/AlAs/GaAs heterostructu…
