Open quantum systems with particle and bath driven by time-dependent fields
Daniele Gamba, Bingyu Cui, Alessio Zaccone
We derive a generalized quantum Langevin equation and its fluctuation-dissipation relation describing the quantum dynamics of a tagged particle interacting with a medium (environme…

Hyperballistic transport in dense systems of charged particles under ac electric fields
Daniele Gamba, Bingyu Cui, Alessio Zaccone
The Langevin equation is ubiquitously employed to numerically simulate plasmas, colloids and electrolytes. However, the usual assumption of white noise becomes untenable when the s…
