Prethermal ripplons in quenched binary Bose-Einstein condensates
Yanda Geng, Stephen Eckel, Gretchen K. Campbell +1
Prethermal states--long-lived quasi-equilibrium configurations--occur in a wide range of physical systems that exhibit fast dephasing or reconfiguration followed by slow relaxation…
Q-GAIN: A Python Package for Machine Learning and Physically Informed Analysis Applications
M. Doris, S. Guo, S. M. Koh +5
Here we describe the quantum gas analysis and inference (Q-GAIN) Python package, which enables rapid deployment of machine learning (ML) and physics-informed analysis techniques fo…
Can machine learning for quantum-gas experiments be explainable?
I. B. Spielman amd J. P. Zwolak
Virtually all aspects of many-body atomic physics are challenging: experiments are technically demanding, datasets have become enormous, and the memory and CPU requirements for cla…
Repeated weak measurements: watching quantum correlations evolve
Emine Altuntas, Ian B. Spielman
Experimental access to many-body quantum systems is often limited by measurement backaction, and key dynamical properties are typically obtained by perturbing a system and measurin…
Nondestructive characterization of laser-cooled atoms using machine learning
G. De Sousa, M. Doris, D. D'Amato +3
We develop machine learning techniques for estimating physical properties of laser-cooled potassium-39 atoms in a magneto-optical trap using only the scattered light -- i.e., fluor…
Efficient production of sodium Bose-Einstein condensates in a hybrid trap
Yanda Geng, Shouvik Mukherjee, Swarnav Banik +6
We describe an apparatus that efficiently produces Na Bose-Einstein condensates (BECs) in a hybrid trap that combines a quadrupole magnetic field with a far-detuned optical…
Imaginary gauge potentials in a non-Hermitian spin-orbit coupled quantum gas
Junheng Tao, Emmanuel Mercado-Gutierrez, Mingshu Zhao +1
In 1996, Hatano and Nelson proposed a non-Hermitian lattice model containing an imaginary Peierls phase [Phys. Rev. Lett. 77 570-573 (1996)], which subsequent analyses revealed to…
The Rayleigh-Taylor instability in a binary quantum fluid
Yanda Geng, Junheng Tao, Mingshu Zhao +4
Instabilities, where small fluctuations seed the formation of large-scale structures, govern dynamics in a variety of fluid systems. The Rayleigh-Taylor instability (RTI), present…
Dynamical Structure Factor from Weak Measurements
E. Altuntas, R. G. Lena, S. Flannigan +2
Much of our knowledge of quantum systems is encapsulated in the expectation value of Hermitian operators, experimentally obtained by averaging projective measurements. However, dyn…
Kolmogorov turbulence in atomic Bose-Einstein condensates
Mingshu Zhao, Junheng Tao, Ian Spielman
We investigated turbulence in atomic Bose-Einstein condensates (BECs) using a minimally destructive, impurity injection technique analogous to particle image velocimetry in convent…
Dark solitons in Bose-Einstein condensates: a dataset for many-body physics research
Amilson R. Fritsch, Shangjie Guo, Sophia M. Koh +2
We establish a dataset of over experimental images of Bose--Einstein condensates containing solitonic excitations to enable machine learning (ML) for many-body phys…
Combining machine learning with physics: A framework for tracking and sorting multiple dark solitons
Shangjie Guo, Sophia M. Koh, Amilson R. Fritsch +2
In ultracold-atom experiments, data often comes in the form of images which suffer information loss inherent in the techniques used to prepare and measure the system. This is parti…
Accurate Determination of Hubble Attenuation and Amplification in Expanding and Contracting Cold-Atom Universes
S. Banik, M. Gutierrez Galan, H. Sosa-Martinez +4
In the expanding universe, relativistic scalar fields are thought to be attenuated by "Hubble friction", which results from the dilation of the underlying spacetime metric. By cont…
Enhanced transport of spin-orbit coupled Bose gases in disordered potentials
Y. Yue, C. A. R. Sá de Melo, I. B. Spielman
Anderson localization is a single particle localization phenomena in disordered media that is accompanied by an absence of diffusion. Spin-orbit coupling (SOC) describes an interac…
Realization of a fractional period adiabatic superlattice
R. P. Anderson, D. Trypogeorgos, A. Valdés-Curiel +6
We propose and realize a deeply sub-wavelength optical lattice for ultracold neutral atoms using resonantly Raman-coupled internal degrees of freedom. Although counter-propagat…
