Gauge matters: Observing the vortex-nucleation transition in a Bose condensate
L. J. LeBlanc, K. Jiménez-García, R. A. Williams +3
The order parameter of a quantum-coherent many-body system can include a phase degree of freedom, which, in the presence of an electromagnetic field, depends on the choice of gauge…
Tunable Spin-Orbit Coupling via Strong Driving in Ultracold Atom Systems
K. Jiménez-García, L. J. LeBlanc, R. A. Williams +5
Spin-orbit coupling (SOC) is an essential ingredient in topological materials, conventional and quantum-gas based alike.~Engineered spin-orbit coupling in ultracold atom systems --…
A Raman-induced Feshbach resonance in an effectively single-component Fermi gas
R. A. Williams, M. C. Beeler, L. J. LeBlanc +2
Ultracold gases of interacting spin-orbit coupled fermions are predicted to display exotic phenomena such as topological superfluidity and its associated Majorana fermions. Here, w…
The spin Hall effect in a quantum gas
M. C. Beeler, R. A. Williams, K. Jiménez-García +3
Electronic properties like current flow are generally independent of the electron's spin angular momentum, an internal degree of freedom present in quantum particles. The spin Hall…
Direct observation of zitterbewegung in a Bose-Einstein condensate
L. J. LeBlanc, M. C. Beeler, K. Jimenez-Garcia +4
Zitterbewegung, a force-free trembling motion first predicted for relativistic fermions like electrons, was an unexpected consequence of the Dirac equation's unification of quantum…
Dynamically Slowed Collapse of a Bose-Einstein Condensate with Negative Scattering Length
R. L. Compton, Y. -J. Lin, K. Jimenez-Garcia +2
We rapidly change the scattering length a_s of a 87Rb Bose-Einstein condensate by means of a Feshbach resonance, simultaneously releasing the condensate from its harmonic trapping…
The Peierls substitution in an engineered lattice potential
K. Jiménez-García, L. J. LeBlanc, R. A. Williams +3
Artificial gauge fields open new possibilities to realize quantum many-body systems with ultracold atoms, by engineering Hamiltonians usually associated with electronic systems. In…
Observation of a superfluid Hall effect
L. J. LeBlanc, K. Jimenez-Garcia, R. A. Williams +4
Measurement techniques based upon the Hall effect are invaluable tools in condensed matter physics. When an electric current flows perpendicular to a magnetic field, a Hall voltage…
Synthetic partial waves in ultracold atomic collisions
R. A. Williams, L. J. LeBlanc, K. Jimenez-Garcia +4
Interactions between particles can be strongly altered by their environment. We demonstrate a technique for modifying interactions between ultracold atoms by dressing the bare atom…
A spin-orbit coupled Bose-Einstein condensate
Y. -J. Lin, K. Jiménez-García, I. B. Spielman
Spin-orbit (SO) coupling -- the interaction between a quantum particle's spin and its momentum -- is ubiquitous in nature, from atoms to solids. In condensed matter systems, SO cou…
A synthetic electric force acting on neutral atoms
Yu-Ju Lin, Robert L. Compton, Karina Jimenez-Garcia +3
Electromagnetism is a simple example of a gauge theory where the underlying potentials -- the vector and scalar potentials -- are defined only up to a gauge choice. The vector pote…
Synthetic magnetic fields for ultracold neutral atoms
Yu-Ju Lin, Rob L. Compton, Karina J. Garcia +2
Neutral atomic Bose condensates and degenerate Fermi gases have been used to realize important many-body phenomena in their most simple and essential forms, without many of the com…
Phases of a 2D Bose Gas in an Optical Lattice
K. Jimenez-Garcia, R. L. Compton, Y. -J. Lin +3
Ultra-cold atoms in optical lattices realize simple, fundamental models in condensed matter physics. Our 87Rb Bose-Einstein condensate is confined in a harmonic trapping potential…
