Variance Sum Rule for Entropy Production
I. Di Terlizzi, M. Gironella, D. Herraez-Aguilar +4
Entropy production is the hallmark of nonequilibrium physics, quantifying irreversibility, dissipation, and the efficiency of energy transduction processes. Despite many efforts, i…
Dynamics of parametric matter wave amplification
Robert Bücker, Ulrich Hohenester, Tarik Berrada +7
We develop a model for parametric amplification, based on a density matrix approach, which naturally accounts for the peculiarities arising for matter waves: significant depletion…
Shapiro effect in atomchip-based bosonic Josephson junctions
Julian Grond, Thomas Betz, Ulrich Hohenester +3
We analyze the emergence of Shapiro resonances in tunnel-coupled Bose-Einstein condensates, realizing a bosonic Josephson junction. Our analysis is based on an experimentally relev…
Hanbury Brown and Twiss correlations across the Bose-Einstein condensation threshold
Aurélien Perrin, Robert Bücker, Stephanie manz +5
Hanbury Brown and Twiss (HBT) correlations, i.e. correlations in far-field intensity fluctuations, yield fundamental information on the quantum statistics of light sources, as high…
Twin-atom beams
Robert Bücker, Julian Grond, Stephanie Manz +7
We present highly efficient emission of twin-atom beams into a single transversal mode of a waveguide potential. The source is a one-dimensional degenerate Bose gas in the first ra…
Two-point phase correlations of a one-dimensional bosonic Josephson junction
Thomas Betz, Stephanie Manz, Robert Bücker +8
We realize a one-dimensional Josephson junction using quantum degenerate Bose gases in a tunable double well potential on an atom chip. Matter wave interferometry gives direct acce…
