Non-perturbative switching rates in bistable open quantum systems: from driven Kerr oscillators to dissipative cat qubits
Léon Carde, Ronan Gautier, Nicolas Didier +3
In this work, we use path integral techniques to predict the switching rate in a single-mode bistable open quantum system. While analytical expressions are well-known to be accessi…

The Frenkel line and the pseudogap: an analogy between classical and electronic fluids
J. Fournier, P. -O. Downey, O. Gingras +3
Asymptotically close to critical end-points of first-order transitions, maxima in thermodynamic quantities occur along a line called the Widom line, a concept first introduced in c…
