Monitoring squeezed collective modes of a one-dimensional Bose gas after an interaction quench using density ripples analysis
Max Schemmer, Aisling Johnson, Isabelle Bouchoule
We investigate the out-of-equilibrium dynamics following a sudden quench of the interaction strength, in a one-dimensional quasi-condensate trapped at the surface of an atom chip.…
Long-lived non-thermal states realized by atom losses in one-dimensional quasi-condensates
A. Johnson, S. Szigeti, M. Schemmer +1
We investigate the cooling produced by a loss process non selective in energy on a one-dimensional (1D) Bose gas with repulsive contact interactions in the quasi-condensate regime.…
A Monte Carlo wavefunction description of losses in a 1D Bose gas and cooling to the ground state by quantum feedback
Maximilian Schemmer, Aisling Johnson, Raphael Photopoulos +1
The effect of atom losses on a homogeneous one-dimensional Bose gas lying within the quasi-condensate regime is investigated using a Monte Carlo wavefunction approach. The evolutio…
Observation of scaling in the dynamics of a strongly quenched quantum gas
Eike Nicklas, Markus Karl, Moritz Höfer +6
We report on the experimental observation of scaling in the time evolution following a sudden quench into the vicinity of a quantum critical point. The experimental system, a two-c…
Momentum-space correlations of a one-dimensional Bose gas
Bess Fang, Aisling Johnson, Tommaso Roscilde +1
Analyzing the noise in the momentum profiles of single realizations of one-dimensional Bose gases, we present the experimental measurement of the full momentum-space density correl…
Quench-induced breathing mode of one-dimensional Bose gases
Bess Fang, Giuseppe Carleo, Aisling Johnson +1
We measure the position- and momentum- space breathing dynamics of trapped one-dimensional Bose gases. The profile in real space reveals sinusoidal width oscillations whose frequen…
