Dynamics of Ultracold Bosons in Artificial Gauge Fields: Angular Momentum, Fragmentation, and the Variance of Entropy
Axel U. J. Lode, Sunayana Dutta, Camille Lévêque
We consider the dynamics of two-dimensional interacting ultracold bosons triggered by suddenly switching on an artificial gauge field. The system is initialized in the ground state…
Relaxation in an Extended Bosonic Josephson Junction
Jan-Frederik Mennemann, Igor E. Mazets, Marine Pigneur +4
We present a detailed analysis of the relaxation dynamics in an extended bosonic Josephson junction. We show that stochastic classical field simulations using Gross-Pitaevskii equa…
Unipotent -blocks for simply-connected -adic groups
Thomas Lanard
Let be a non-archimedean local field and the -points of a connected simply-connected reductive group over . In this paper, we study the unipotent -blocks of …
Optimized Observable Readout from Single-shot Images of Ultracold Atoms via Machine Learning
Axel U. J. Lode, Rui Lin, Miriam Büttner +6
Single-shot images are the standard readout of experiments with ultracold atoms -- the tarnished looking glass into their many-body physics. The efficient extraction of observables…
Prediction of magnetization dynamics in a reduced dimensional feature space setting utilizing a low-rank kernel method
Lukas Exl, Norbert J. Mauser, Sebastian Schaffer +2
We establish a machine learning model for the prediction of the magnetization dynamics as function of the external field described by the Landau-Lifschitz-Gilbert equation, the par…
Unruh and analogue Unruh temperatures for circular motion in 3+1 and 2+1 dimensions
Steffen Biermann, Sebastian Erne, Cisco Gooding +4
The Unruh effect states that a uniformly linearly accelerated observer with proper acceleration experiences Minkowski vacuum as a thermal state in the temperature $T_{\text{lin…
