Equilibrium and non-equilibrium phases of microwave-dressed polar molecules beyond rotational symmetries
Matteo Ciardi, Andreas Schindewolf, Tim Langen +1
Recent experiments on molecular droplets have opened a new frontier of self-organization in strongly dipolar quantum matter. Microwave-dressing of polar molecules permits to tune b…
Strongly dipolar molecular Bose-Einstein condensates: From few- to many-body physics
Andreas Schindewolf, Jens Hertkorn, Ian Stevenson +8
Recent advances in molecular cooling have enabled the realization of strongly dipolar Bose--Einstein condensates (BECs) of molecules, and BECs of many different molecular species m…
Roton Excitations in an Oblate Dipolar Quantum Gas
Jan-Niklas Schmidt, Jens Hertkorn, Mingyang Guo +7
We observe signatures of radial and angular roton excitations around a droplet crystallization transition in dipolar Bose-Einstein condensates. In situ measurements are used to cha…
Density Fluctuations across the Superfluid-Supersolid Phase Transition in a Dipolar Quantum Gas
J. Hertkorn, J. -N. Schmidt, F. Böttcher +8
Phase transitions share the universal feature of enhanced fluctuations near the transition point. Here we show that density fluctuations reveal how a Bose-Einstein condensate of di…
Double light-cone dynamics establish thermal states in integrable 1D Bose gases
Tim Langen, Thomas Schweigler, Eugene Demler +1
We theoretically investigate the non-equilibrium dynamics in a quenched pair of 1D Bose gases with density imbalance. We describe the system using its low-energy effective theory,…
Does an isolated quantum system relax?
B. Rauer, T. Schweigler, T. Langen +1
Statistical mechanics is one of the most comprehensive theories in physics. From a boiling pot of water to the complex dynamics of quantum many-body systems it provides a successfu…
Towards experimental quantum field tomography with ultracold atoms
A. Steffens, M. Friesdorf, T. Langen +6
The experimental realisation of large scale many-body systems has seen immense progress in recent years, rendering full tomography tools for state identification inefficient, espec…
Local relaxation and light-cone-like propagation of correlations in a trapped one-dimensional Bose gas
Remi Geiger, Tim Langen, Igor Mazets +1
We describe the relaxation dynamics of a coherently split one-dimensional (1D) Bose gas in the harmonic approximation. A dephased, prethermalized state emerges in a light-cone-like…
Lifetime of the Bose Gas with Resonant Interactions
B. S. Rem, A. T. Grier, I. Ferrier-Barbut +8
We study the lifetime of a Bose gas at and around unitarity using a Feshbach resonance in lithium~7. At unitarity, we measure the temperature dependence of the three-body decay coe…
