Optomechanical systems with a Fano membrane in the middle
Lei Du, Aymeric Frerejean, Witlef Wieczorek +2
Conventional membrane-in-the-middle (MIM) optomechanical systems offer limited control over the optical linewidth, which can limit their performance when operating in the unresolve…
Precision of an autonomous demon exploiting nonthermal resources and information
Juliette Monsel, Matteo Acciai, Didrik Palmqvist +3
Quantum-dot systems serve as nanoscale heat engines exploiting thermal fluctuations to perform a useful task. Here, we investigate a multi-terminal triple-dot system, operating as…
Dressed Interference in Giant Superatoms: Entanglement Generation and Transfer
Lei Du, Xin Wang, Anton Frisk Kockum +1
We introduce the concept of giant superatoms (GSAs), where two or more interacting atoms are nonlocally coupled to a waveguide through one of them, and explore their unconventional…
Role of electron-electron interaction in the Mpemba effect in quantum dots
Juliane Graf, Janine Splettstoesser, Juliette Monsel
The Mpemba effect has initially been noticed in macroscopic systems -- namely that hot water can freeze faster than cold water -- but recently its extension to open quantum systems…
Autonomous demon exploiting heat and information at the trajectory level
Juliette Monsel, Matteo Acciai, Rafael Sánchez +1
We propose an electronic bipartite system consisting of a working substance, in which a refrigeration process is implemented, and of a nonthermal resource region, containing a comb…
Coherent feedback control for cavity optomechanical systems with a frequency-dependent mirror
Lei Du, Juliette Monsel, Witlef Wieczorek +1
Ground-state cooling of mechanical resonators is a prerequisite for the observation of various quantum effects in optomechanical systems and thus has always been a crucial task in…
