Dual-species alkali and alkaline-earth-like optical tweezer arrays via interferometrically aligned high-NA objectives
K. Weber, M. McMaster, M. Anderson +7
We have developed a dual-species optical tweezer array apparatus combining and atoms with a permanent hybrid Twyman-Green--Fizeau interferometer,…
Measurement resolution enhanced coherence for lattice fermions
H. M. Hurst, Yik Haw Teoh, I. B. Spielman
Weak measurement enables the extraction of targeted information from a quantum system while minimizing decoherence due to measurement backaction. However, in many-body quantum syst…
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…
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…
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…
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…
Feedback-stabilized dynamical steady states in the Bose-Hubbard model
Jeremy T. Young, Alexey V. Gorshkov, I. B. Spielman
The implementation of a combination of continuous weak measurement and classical feedback provides a powerful tool for controlling the evolution of quantum systems. In this work, w…
Wilson loop and Wilczek-Zee phase from a non-Abelian gauge field
Seiji Sugawa, Francisco Salces-Carcoba, Yuchen Yue +2
Quantum states can acquire a geometric phase called the Berry phase after adiabatically traversing a closed loop, which depends on the path not the rate of motion. The Berry phase…
Fourier transform spectroscopy of a spin-orbit coupled Bose gas
A. Valdés-Curiel, D. Trypogeorgos, E. E. Marshall +1
We describe a Fourier transform spectroscopy technique for directly measuring band structures, and apply it to a spin-1 spin-orbit coupled Bose-Einstein condensate. In our techniqu…
Position-dependent spin-orbit coupling for ultracold atoms
S. -W. Su, S. -C. Gou, I. -K. Liu +6
We theoretically explore atomic Bose-Einstein condensates (BECs) subject to position-dependent spin-orbit coupling (SOC). This SOC can be produced by cyclically laser coupling four…
