On-site interactions in quantum thermal machines: efficiency, rectification and entanglement beyond local and global master equations
Salvatore Araceli, Teddy H. M. Ong, Baptiste Debecker +4
Advances in experimental techniques have opened new routes for harnessing non-equilibrium dynamics in mesoscopic quantum systems. In this context, we study the impact of on-site in…
Fibonacci Steady-States and Persistent Oscillations in an Ordered Multimode Dicke Model
Miriam J. Leonhardt, Kai Müller, Oliver Lunt +1
Ultracold atoms in multimode optical cavities provide a rich testbed for many-body phenomena enabled by light-mediated interactions. Recent experiments include realizations of spin…
One-to-one correspondence between Hierarchical Equations of Motion and Pseudomodes for Open Quantum System Dynamics
Kai Müller, Walter T. Strunz
We unite two of the most widely used approaches for strongly damped, non-Markovian open quantum dynamics, the Hierarchical Equations of Motion (HEOM) and the pseudomode method by p…
Deterministic Control of Photon-Number Probabilities via Phase-Controlled Quantum Interference
Sang Kyu Kim, Eduardo Zubizarreta Casalengua, Yeji Sim +8
Deterministically tailoring optical Fock states beyond the single-photon level is crucial for boson sampling, loss-tolerant photonic qubits, and quantum-enhanced sensing, however h…
Dynamically Dressed States of a Quantum Four-Level System
Carolin Calcagno, Friedrich Sbresny, Thomas K. Bracht +8
In this work, we experimentally and theoretically study the dressed-state emission of the biexciton-exciton cascade in a semiconductor quantum dot under pulsed, resonant, two-photo…
