Excitation of time-dependent quantum systems:an application of time-energy uncertainty relations

Tarek Khalil, Jean Richert

The conditions under which time-energy uncertainty relations derived by Deffner and Lutz [10] for time-dependent quantum systems minimize the time necessary to excite such systems…

Environment Induced Time Arrow and the Closed Time Path method

Janos Polonyi

It is shown in the framework of a harmonic system that the thermodynamical time arrow is induced by the environmental initial conditions in a manner similar to spontaneous symmetry…

Variational approach to the time-dependent Schrödinger-Newton equations

Giovanni Manfredi, Paul-Antoine Hervieux, Fernando Haas

Using a variational approach based on a Lagrangian formulation and Gaussian trial functions, we derive a simple dynamical system that captures the main features of the time-depende…

Quantum-correlated motion and heralded entanglement of distant optomechanically coupled objects

Wolfgang Niedenzu, Raimar M. Sandner, Claudiu Genes +1

The motion of two distant trapped particles or mechanical oscillators can be strongly coupled by light modes in a high finesse optical resonator. In a two mode ring cavity geometry…

Engineered Open Systems and Quantum Simulations with Atoms and Ions

M. Müller, S. Diehl, G. Pupillo +1

The enormous experimental progress in atomic, molecular and optical (AMO) physics during the last decades allows us nowadays to isolate single, a few or even many-body ensembles of…

Strong coupling and long-range collective interactions in optomechanical arrays

André Xuereb, Claudiu Genes, Aurélien Dantan

We investigate the collective optomechanics of an ensemble of scatterers inside a Fabry-Perot resonator and identify an optimized configuration where the ensemble is transmissive,…
