Open quantum systems in thermal non-ergodic environments

Carlos A. Parra-Murillo, Max Bramberger, Claudius Hubig +1

The dynamics of an open system crucially depends on the correlation function of its environment, . We show that for thermal non-Harmonic environments may not decay…

Typicality in the foundations of statistical physics and Born's rule

Detlef Dürr, Ward Struyve

Typicality has always been in the minds of the founding fathers of probability theory when probabilistic reasoning is applied to the real world. However, the role of typicality is…

Multipartite Entanglement Analysis From Random Correlations

Lukas Knips, Jan Dziewior, Waldemar Kłobus +5

Quantum entanglement is usually revealed via a well aligned, carefully chosen set of measurements. Yet, under a number of experimental conditions, for example in communication with…

Long-distance distribution of atom-photon entanglement at telecom wavelength

Tim van Leent, Matthias Bock, Robert Garthoff +6

Entanglement between stationary quantum memories and photonic channels is the essential resource for future quantum networks. Together with entanglement distillation it will enable…

Nonlinear dynamics of weakly dissipative optomechanical systems

Thales Figueiredo Roque, Florian Marquardt, Oleg M. Yevtushenko

Optomechanical systems attract a lot of attention because they provide a novel platform for quantum measurements, transduction, hybrid systems, and fundamental studies of quantum p…

Implications of pinned occupation numbers for natural orbital expansions. II: Rigorous derivation and extension to non-fermionic systems

Tomasz Maciążek, Adam Sawicki, David Gross +2

We have explained and comprehensively illustrated in Part I that the generalized Pauli constraints suggest a natural extension of the concept of active spaces. In the present Part…

Implications of pinned occupation numbers for natural orbital expansions. I: Generalizing the concept of active spaces

Christian Schilling, Carlos L. Benavides-Riveros, Alexandre Lopes +2

The concept of active spaces simplifies the description of interacting quantum many-body systems by restricting to a neighbourhood of active orbitals around the Fermi level. The re…

Dephasing dynamics of an impurity coupled to an anharmonic environment

Max Bramberger, Inés De Vega

We analyze the dephasing dynamics of an impurity coupled to an anharmonic environment. We show that a strong anharmonicity produces two different effects depending on the environme…

Chiral quantum optics in photonic sawtooth lattices

Eduardo Sánchez-Burillo, Chao Wan, David Zueco +1

Chiral quantum optics has become a burgeoning field due to its potential applications in quantum networks or quantum simulation of many-body physics. Current implementations are ba…

Measurements of nonlocal variables and demonstration of the failure of the product rule for a pre- and postselected pair of photons

Xiao-Ye Xu, Wei-Wei Pan, Qin-Qin Wang +9

We report the first implementation of the von Neumann instantaneous measurements of nonlocal variables which becomes possible due to technological achievements in creating hyperent…

Exotic Bohmian arrival times of spin-1/2 particles I-An analytical treatment

Siddhant Das, Markus Nöth, Detlef Dürr

It is well known that orthodox quantum mechanics does not make unambiguous predictions for the statistics in arrival time (or time-of-flight) experiments. Bohmian mechanics (or de…
