Enhanced continuous generation of non-Gaussianity through optomechanical modulation

Sofia Qvarfort, Alessio Serafini, André Xuereb +2

We study the non-Gaussian character of quantum optomechanical systems evolving under the fully nonlinear optomechanical Hamiltonian. By using a measure of non-Gaussianity based on…

Entanglement properties of a measurement-based entanglement distillation experiment

Hao Jeng, Spyros Tserkis, Jing Yan Haw +5

Measures of entanglement can be employed for the analysis of numerous quantum information protocols. Due to computational convenience, logarithmic negativity is often the choice in…

Endurance of quantum coherence due to particle indistinguishability in noisy quantum networks

Armando Perez-Leija, Diego Guzmán-Silva, Roberto de J. León-Montiel +5

Quantum coherence, the physical property underlying fundamental phenomena such as multi-particle interference and entanglement, has emerged as a valuable resource upon which modern…

Observation of ultra-strong spin-motion coupling for cold atoms in optical microtraps

A. Dareau, Y. Meng, P. Schneeweiss +1

We realize a mechanical analogue of the Dicke model, achieved by coupling the spin of individual neutral atoms to their quantized motion in an optical trapping potential. The atomi…

Quantum Rolling Friction

F. Intravaia, M. Oelschläger, D. Reiche +2

An atom moving in a vacuum at constant velocity and parallel to a surface experiences a frictional force induced by the dissipative interaction with the quantum fluctuations of the…

Quantum thermodynamics of overdamped modes in local and spatially dispersive materials

Daniel Reiche, Kurt Busch, Francesco Intravaia

The quantum thermodynamical properties of (quasi-normal) overdamped electromagnetic modes (eddy currents) are investigated in the context of the magnetic Casimir-Polder interaction…

Nonperturbative and non-Markovian Förster-interaction in waveguiding systems

T. Sproll, Ch. Martens, M. P. Schneider +2

An exact solution to the interaction between two emitters mediated by Förster resonance energy transfer is presented. The system is comprised of a one-dimensional optical waveguide…

Modified dipole-dipole interaction and dissipation in an atomic ensemble near surfaces

Ryan Jones, Jemma A. Needham, Igor Lesanovsky +2

We study how the radiative properties of a dense ensemble of atoms can be modified when they are placed near or between metallic or dielectric surfaces. If the average separation b…
