Non-Markovian dynamics of the giant atom beyond the rotating-wave approximation
Mei Yu, Walter T. Strunz, Stefan Nimmrichter
We study the non-Markovian dynamics of a giant artificial atom coupled to a one-dimensional acoustic waveguide beyond the rotating-wave and weak-coupling approximations. By combini…

Quantum memory in spontaneous emission processes
Mei Yu, Ties-A. Ohst, Hai-Chau Nguyen +1
Quantum memory effects are essential in understanding and controlling open quantum systems, yet distinguishing them from classical memory remains challenging. We introduce a convex…
