Abstract: We investigate the effect of counter-rotating-wave terms on the non-Markovianity in quantum open systems by employing the hierarchical equations of motion in the framework of the non-Markovian quantum state diffusion approach. As illustrative examples, the… read more here.

DOI: 10.1103/physrevb.100.041103
Abstract: We study one-dimensional Floquet topological insulators with chiral symmetry going beyond the standard rotating wave approximation. The occurrence of many anticrossings between Floquet replicas leads to a dramatic extension of phase diagram regions with stable… read more here.

Abstract: We investigate the vibrational dynamics of a quantum mechanical resonator when an ensemble of laser pumped two-level emitters are fixed on it. Beyond the rotating wave approximation with respect to phonon’s variables, one can obtain… read more here.

DOI: 10.1364/oe.25.030135
Abstract: The technique of shortcuts to adiabaticity (STA) has attracted broad attention due to their possible applications in quantum information processing and quantum control. However, most studies published so far have been only focused on Hermitian… read more here.
