Universal dynamics from a single-particle dark state
Ruben Daraban, Arghavan Safavi-Naini, Johannes Schachenmayer +1
Open quantum systems can host dark or subradiant states whose decay is highly suppressed. While these states have been extensively studied in the few-excitation regime, their impac…

Disorder-induced non-Gaussian states in large ensembles of cavity-coupled molecules
R. Schwengelbeck, M. Pandini, R. Daraban +1
We analyze vibrational dynamics in a toy model for polaritonic chemistry under collective electronic strong coupling. In a Holstein-Tavis-Cummings model, incoherently excited by a…

Non-unitarity maximizing unraveling of open quantum dynamics
Ruben Daraban, Fabrizio Salas-RamÃrez, Johannes Schachenmayer
The dynamics of many-body quantum states in open systems is commonly numerically simulated by unraveling the density matrix into pure-state trajectories. In this work, we introduce…
