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…
Nonlinear quantum optomechanics in a Fano-mirror microcavity system
Lei Du, Juliette Monsel, Witlef Wieczorek +1
We study a Fano-mirror optomechanical system in the quantum nonlinear regime. In this system, two strongly lossy optical modes hybridize through both coherent and dissipative coupl…
Sources of nonlinearity in the response of a driven nano-electromechanical resonator
Sofia Sevitz, Kushagra Aggarwal, Jorge Tabanera-Bravo +9
Nanoelectromechanical resonators provide an ideal platform for investigating the interplay between electron transport and nonlinear mechanical motion. Externally driven suspended c…
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…
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…
