Bound on dissipative effects from semileptonic neutral B-meson decays
F. Benatti, R. Floreanini, S. Marcantoni +2
The semileptonic decay asymmetry is studied within the open quantum systems approach to the physics of the neutral meson - system: this exte…
Quantum interferences reconstruction with low homodyne detection efficiency
M. Esposito, F. Randi, K. Titimbo +7
Standard quantum state reconstruction techniques indicate that a detection efficiency of is an absolute threshold below which quantum interferences cannot be measured. Howeve…
Photon number statistics uncover the fluctuations in non-equilibrium lattice dynamics
Martina Esposito, Kelvin Titimbo, Klaus Zimmermann +7
Fluctuations of the atomic positions are at the core of a large class of unusual material properties ranging from quantum para-electricity to high temperature superconductivity. Th…
Extracting partial decay rates of helium from complex rotation: autoionizing resonances of the one-dimensional configurations
Klaus Zimmermann, Pierre Lugan, Felix Jörder +5
Partial autoionization rates of doubly excited one-dimensional helium in the collinear Zee and eZe configuration are obtained by means of the complex rotation method. The approach…
Interaction effects on dynamical localization in driven helium
Felix Jörder, Klaus Zimmermann, Alberto Rodriguez +1
Dynamical localization prevents driven atomic systems from fast fragmentation by hampering the excitation process. We present numerical simulations within a collinear model of micr…
Tunneling decay of two interacting bosons in an asymmetric double-well potential: A spectral approach
Stefan Hunn, Klaus Zimmermann, Moritz Hiller +1
We study the full-fledged microscopic dynamics of two interacting, ultracold bosons in a one- dimensional double-well potential, through the numerically exact diagonalization of th…
