Generation of dark-bright soliton trains in superfluid-superfluid counterflow
C. Hamner, J. J. Chang, P. Engels +1
The dynamics of two penetrating superfluids exhibit an intriguing variety of nonlinear effects. Using two distinguishable components of a Bose-Einstein condensate, we investigate t…
Dynamics of Dark-Bright Solitons in Cigar-Shaped Bose-Einstein Condensates
S. Middelkamp, J. J. Chang, C. Hamner +6
We explore the stability and dynamics of dark-bright solitons in two-component elongated Bose-Einstein condensates by developing effective 1D vector equations as well as solving th…
Intermediate-Range Order in Water Ices
T. T. Fister, K. P. Nagle, F. D. Vila +4
We report measurements of the non-resonant inelastic x-ray scattering (NRIXS) from the O 1s orbitals in ice Ih, and also report calculations of the corresponding spectra for ice Ih…
Beating dark-dark solitons in Bose-Einstein condensates
D. Yan, J. J. Chang, C. Hamner +6
Motivated by recent experimental results, we study beating dark-dark solitons as a prototypical coherent structure that emerges in two-component Bose-Einstein condensates. We showc…
Dark-dark solitons and modulational instability in miscible, two-component Bose-Einstein condensates
M. A. Hoefer, J. J. Chang, C. Hamner +1
We investigate the dynamics of two miscible superfluids experiencing fast counterflow in a narrow channel. The superfluids are formed by two distinguishable components of a trapped…

We report new measurements and calculations of the non-resonant inelastic x-ray scattering (NRIXS) from Mg and Al for a wide range of momentum transfers, q. Extended oscillations i…
Scattering of atomic dark-bright solitons from narrow impurities
A. Ãlvarez, J. Cuevas, F. R. Romero +5
In this work, we study the collision of an atomic dark-bright soliton, in a two-component Bose-Einstein condensate, with a Gaussian barrier or well. First, we present the results o…
Multiple dark-bright solitons in atomic Bose-Einstein condensates
D. Yan, J. J. Chang, C. Hamner +6
We present experimental results and a systematic theoretical analysis of dark-br ight soliton interactions and multiple-dark-bright soliton complexes in atomic t wo-component Bose-…
Phase Winding a Two-Component BEC in an Elongated Trap: Experimental Observation of Moving Magnetic Orders and Dark-bright Solitons
C. Hamner, Yongping Zhang, J. J. Chang +2
We experimentally investigate the phase winding dynamics of a harmonically trapped two-component BEC subject to microwave induced Rabi oscillations between two pseudospin component…
Spin-orbit coupled Bose-Einstein condensates in a one-dimensional optical lattice
C. Hamner, Yongping Zhang, M. A. Khamehchi +2
The realization of artificial gauge fields and spin-orbit coupling for ultra-cold quantum gases promises new insight into paradigm solid state systems. Here we experimentally probe…
