Non-Markovian steady states of a driven two-level system

no code implementations22 Feb 2021 Andreas Ask, Göran Johansson

We find that some non-Markovian states show exotic behaviors such as population inversion and steady-state coherence beyond $1/\sqrt{8}$, neither of which is possible for a driven TLS in the Markovian regime, where the time delay is neglected.

Cavity-free vacuum-Rabi splitting in circuit quantum acoustodynamics

no code implementations23 Nov 2018 Andreas Ask, Maria Ekström, Per Delsing, Göran Johansson

Most notably, we find this regime hard to avoid for an atom on top of a strong piezoelectric material, such as LiNbO$_3$.
