Efficient non-Markovian quantum dynamics using time-evolving matrix product operators
Aidan Strathearn, Peter Kirton, Dainius Kilda +2
In order to model realistic quantum devices it is necessary to simulate quantum systems strongly coupled to their environment. To date, most understanding of open quantum systems i…
Analytical description of spontaneous emission of light at the optical event horizon
Maxime J Jacquet, Friedrich König
Quantum fluctuations in curved space-time cause the emission of particles. In order to understand how they may be detected in a laboratory experiment, we consider a moving refracti…
Trading quantum states for temporal profiles: tomography by the overlap
Johannes Tiedau, Valery S. Shchesnovich, Dmitri Mogilevtsev +5
Quantum states and the modes of the optical field they occupy are intrinsically connected. Here, we show that one can trade the knowledge of a quantum state to gain information abo…
Boundary time crystals
F. Iemini, A. Russomanno, J. Keeling +3
In this work we introduce {\it boundary time-crystals}. Here {\it continuous} time-translation symmetry breaking occurs only in a macroscopic fraction of a many-body quantum system…
Signatures of a dissipative phase transition in photon correlation measurements
Thomas Fink, Anne Schade, Sven Höfling +2
Understanding and characterizing phase transitions in driven-dissipative systems constitutes a new frontier for many-body physics. A generic feature of dissipative phase transition…
Intrinsic and environmental effects on the interference properties of a high-performance quantum dot single photon source
Stefan Gerhardt, Jake Iles-Smith, Dara P. S. McCutcheon +7
We report a joint experimental and theoretical study of the interference properties of a single photon source based on a In(Ga)As quantum dot embedded in a quasi-planar GaAs-microc…
