Controlling the dynamics of an open many-body quantum system with localized dissipation
G. Barontini, R. Labouvie, F. Stubenrauch +3
We experimentally investigate the action of a localized dissipative potential on a macroscopic matter wave, which we implement by shining an electron beam on an atomic Bose-Einstei…
Spatio-temporal Fermionization of Strongly Interacting 1D Bosons
V. Guarrera, D. Muth, R. Labouvie +4
Building on the recent experimental achievements obtained with scanning electron microscopy on ultracold atoms, we study one-dimensional Bose gases in the crossover between the wea…
Observation of local temporal correlations in trapped quantum gases
Vera Guarrera, Peter Wuertz, Arne Ewerbeck +3
We measure the temporal pair correlation function of a trapped gas of bosons above and below the critical temperature for Bose-Einstein condensation. The measurement i…
All-optical switching and strong coupling using tunable whispering-gallery-mode microresonators
D. O'Shea, C. Junge, M. Poellinger +2
We review our recent work on tunable, ultrahigh quality factor whispering-gallery-mode bottle microresonators and highlight their applications in nonlinear optics and in quantum op…
