Quantization of the mean decay time for non-Hermitian quantum systems
Felix Thiel, David A. Kessler, Eli Barkai
We show that the mean time, which a quantum particle needs to escape from a system to the environment, is quantized and independent from most dynamical details of the system. In pa…
Entropic uncertainty relations from quantum designs
Andreas Ketterer, Otfried Gühne
In the course of the last decades entropic uncertainty relations have attracted much attention not only due to their fundamental role as manifestation of non-classicality of quantu…
Medium-assisted van der Waals dispersion interactions involving chiral molecules
Hassan Safari, Pablo Barcellona, Stefan Yoshi Buhmann +1
The van der Waals dispersion interaction between two chiral molecules in the presence of arbirary magnetoelectric media is derived using perturbation theory. To be general, the mol…
Structural localization in the Classical and Quantum Fermi-Pasta-Ulam Model
Graziano Amati, Tanja Schilling
We study the statistics and short-times dynamics of the classical and the quantum Fermi-Pasta-Ulam chain in thermal equilibrium. We analyze the distributions of single-particle con…
Universal entanglement losses induced by angular uncertainty
Giacomo Sorelli, Vyacheslav N. Shatokhin, Andreas Buchleitner
We study the diffraction of two maximally entangled qubits encoded into spatial modes of light with orbital angular momenta , on angular apertures. Exploiting the un…
Floquet-engineered vibrational dynamics in a two-dimensional array of trapped ions
Philip Kiefer, Frederick Hakelberg, Matthias Wittemer +4
We demonstrate Floquet engineering in a basic yet scalable 2D architecture of individually trapped and controlled ions. Local parametric modulations of detuned trapping potentials…
