Stationary solitons in F=1 spin-orbit coupled Bose-Einstein condensates
T. Mithun, A. R. Fritsch, G. N. Koutsokostas +3
We consider solitary wave excitations above the ground state of spin-orbit coupled Bose-Einstein condensates (SOBECs). The low energy properties of SOBECs in any of the three…
Critical fluctuations in a confined driven-dissipative quantum condensate
Hassan Alnatah, Paolo Comaron, Shouvik Mukherjee +6
Phase fluctuations determine the low-energy properties of quantum condensates. However, at the condensation threshold, both density and phase fluctuations are relevant. While stron…
Weak-Measurement-Induced Heating in Bose-Einstein Condensates
Emine Altuntas, Ian B. Spielman
Ultracold atoms are an ideal platform for understanding system-reservoir dynamics of many-body systems. Here, we study quantum back-action in atomic Bose-Einstein condensates, weak…
Topological charge pumping with subwavelength Raman lattices
Domantas Burba, Mantas Račiūnas, Ian B. Spielman +1
Recent experiments demonstrated deeply subwavelength lattices using atoms with internal states Raman-coupled with lasers of wavelength . The resulting unit cell was i…
Ballistic transport of a polariton ring condensate with spin precession
Qi Yao, Evgeny Sedov, Shouvik Mukherjee +6
It is now routine to make Bose-Einstein condensates of polaritons with long enough lifetime and low enough disorder to travel ballistically for hundreds of microns in quasi-one-dim…
Quantum Back-action Limits in Dispersively Measured Bose-Einstein Condensates
Emine Altuntas, Ian B. Spielman
A fundamental tenet of quantum mechanics is that measurements change a system's wavefunction to that most consistent with the measurement outcome, even if no observer is present. W…
Dynamical Instability of 3d Stationary and Traveling Planar Dark Solitons
T. Mithun, A. R. Fritsch, I. B. Spielman +1
Here we revisit the topic of stationary and propagating solitonic excitations in self-repulsive three-dimensional Bose-Einstein condensates by quantitatively comparing theoretical…
Feedback cooled Bose-Einstein condensation: near and far from equilibrium
Evan P. Yamaguchi, Hilary M. Hurst, I. B. Spielman
Continuously measured interacting quantum systems almost invariably heat, causing loss of quantum coherence. Here, we study Bose-Einstein condensates (BECs) subject to repeated wea…
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…
Observation of dynamical topology in 1D
G. H. Reid, Mingwu Lu, A. R. Fritsch +2
Nontrivial topology in lattices is characterized by invariants--such as the Zak phase for one dimensional (1D) lattices--derived from wave functions covering the Brillouin zone. We…
Efimov resonance position near a narrow Feshbach resonance in Li-Cs mixture
Ang Li, Yaakov Yudkin, Paul S. Julienne +1
In the vicinity of a narrow Feshbach resonances Efimov features are expected to be characterized by the resonance's properties rather than the van der Waals length of the interatom…
Floquet engineering topological Dirac bands
Mingwu Lu, G. H. Reid, A. R. Fritsch +2
We experimentally realized a time-periodically modulated 1D lattice for ultracold atoms featuring a pair of linear bands, each associated with a Floquet winding number: a topologic…
