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…
Analogue Stochastic Gravity in Strongly-Interacting Bose-Einstein Condensates
Aydin Cem Keser, Victor Galitski
Collective modes propagating in a moving superfluid are known to satisfy wave equations in a curved space time, with a metric determined by the underlying superflow. We use the Kel…
Observation of interspecies Feshbach resonances in an ultracold K-Cs mixture and refinement of interaction potentials
Michael Gröbner, Philipp Weinmann, Emil Kirilov +4
We observe interspecies Feshbach resonances due to s-wave bound states in ultracold K-Cs scattering for three different spin mixtures. The resonances are observed as…
Rydberg optical Feshbach resonances in cold gases
Nóra Sándor, Rosario González-Férez, Paul S. Julienne +1
We propose a novel scheme to efficiently tune the scattering length of two colliding ground-state atoms by off-resonantly coupling the scattering-state to an excited Rydberg-molecu…
Observation of a non-Abelian Yang Monopole: From New Chern Numbers to a Topological Transition
Seiji Sugawa, Francisco Salces-Carcoba, Abigail R. Perry +2
Because global topological properties are robust against local perturbations, understanding and manipulating the topological properties of physical systems is essential in advancin…
Semi-synthetic zigzag optical lattice for ultracold bosons
Egidijus Anisimovas, Mantas Račiūnas, Christoph Sträter +3
We consider a one-dimensional "zigzag" lattice, pictured as a two-site wide single strip taken from a triangular lattice, affected by a tunable homogeneous magnetic flux piercing i…
Wannier functions using a discrete variable representation for optical lattices
Saurabh Paul, Eite Tiesinga
We propose a numerical method using the discrete variable representation (DVR) for constructing real-valued Wannier functions localized in a unit cell for both symmetric and asymme…
Subwavelength-width optical tunnel junctions for ultracold atoms
F. Jendrzejewski, S. Eckel, T. G. Tiecke +4
We propose a new method for creating far-field optical barrier potentials for ultracold atoms with widths that are narrower than the diffraction limit and can approach tens of nano…
Brownian motion of solitons in a Bose-Einstein Condensate
L. M. Aycock, H. M. Hurst, D. K. Efimkin +4
For the first time, we observed and controlled the Brownian motion of solitons. We launched solitonic excitations in highly elongated BECs and showed that a dilute b…
Temperature induced decay of persistent currents in a superfluid ultracold gas
Avinash Kumar, Stephen Eckel, Fred Jendrzejewski +1
We study how temperature affects the lifetime of a quantized, persistent current state in a toroidal Bose-Einstein condensate (BEC). When the temperature is increased, we find a de…
Real space mean-field theory of a spin-1 Bose gas in synthetic dimensions
Hilary M. Hurst, Justin H. Wilson, J. H. Pixley +2
The internal degrees of freedom provided by ultracold atoms give a route for realizing higher dimensional physics in systems with limited spatial dimensions. Non-spatial degrees of…
Multiple scattering dynamics of fermions at an isolated p-wave resonance
Ryan Thomas, Kris O. Roberts, Eite Tiesinga +4
The wavefunction for indistinguishable fermions is anti-symmetric under particle exchange, which directly leads to the Pauli exclusion principle, and hence underlies the structure…
Superfluid transport dynamics in a capacitive atomtronic circuit
Aijun Li, Stephen Eckel, Benjamin Eller +3
We simulate transport in an atomtronic circuit of a Bose-Einstein condensate that flows from a source region into a drain through a gate channel. The time-dependent Gross-Pitaevski…
Vortex Nucleation in a Bose-Einstein Condensate: From the Inside Out
R. M. Price, D. Trypogeorgos, D. L. Campbell +3
We observed a new mechanism for vortex nucleation in Bose-Einstein condensates (BECs) subject to synthetic magnetic fields. We made use of a strong synthetic magnetic field initial…
Nonlinear looped band structure of Bose-Einstein condensates in an optical lattice
Silvio B. Koller, Elizabeth A. Goldschmidt, Roger C. Brown +4
We study experimentally the stability of excited, interacting states of bosons in a double-well optical lattice in regimes where the nonlinear interactions are expected to induce "…
Measurement Protocol for the Entanglement Spectrum of Cold Atoms
Hannes Pichler, Guanyu Zhu, Alireza Seif +2
Entanglement, and, in particular the entanglement spectrum, plays a major role in characterizing many-body quantum systems. While there has been a surge of theoretical works on the…
Mechanism of stimulated Hawking radiation in a laboratory Bose-Einstein condensate
Yi-Hsieh Wang, Ted Jacobson, Mark Edwards +1
We model a sonic black hole analog in a quasi one-dimensional Bose-Einstein condensate, using a Gross-Pitaevskii equation matching the configuration of a recent experiment by Stein…
A 3-photon process for producing a degenerate gas of metastable alkaline-earth atoms
D. S. Barker, N. C. Pisenti, B. J. Reschovsky +1
We present a method for creating a quantum degenerate gas of metastable alkaline-earth atoms. This has yet to be achieved due to inelastic collisions that limit evaporative cooling…
A Hubbard model for ultracold bosonic atoms interacting via zero-point-energy induced three-body interactions
Saurabh Paul, P. R. Johnson, Eite Tiesinga
We show that for ultra-cold neutral bosonic atoms held in a three-dimensional periodic potential or optical lattice, a Hubbard model with dominant, attractive three-body interactio…
Sudden-quench dynamics of Bardeen-Cooper-Schrieffer states in deep optical lattices
Marlon Nuske, L. Mathey, Eite Tiesinga
We determine the exact dynamics of an initial Bardeen-Cooper-Schrieffer (BCS) state of ultra-cold atoms in a deep hexagonal optical lattice. The dynamical evolution is triggered by…
Competing ground states of strongly correlated bosons in the Harper-Hofstadter-Mott model
Stefan S. Natu, Erich J. Mueller, S. Das Sarma
Using an efficient cluster approach, we study the physics of two-dimensional lattice bosons in a strong magnetic field in the regime where the tunneling is much weaker than the on-…
Interacting atomic interferometry for rotation sensing approaching the Heisenberg Limit
Stephen Ragole, Jacob M. Taylor
Atom interferometers provide exquisite measurements of the properties of non-inertial frames. While atomic interactions are typically detrimental to good sensing, efforts to harnes…
