Observation of vector rogue waves in repulsive three-component atomic mixtures
G. A. Bougas, G. C. Katsimiga, S. Mossman +3
Rogue waves are extreme evanescent nonlinear structures that are challenging to observe in atomic gases, as their emergence requires a dynamically unstable attractive environment.…
Nonlinear stage of modulational instability in repulsive two-component Bose-Einstein condensates
S. Mossman, S. I. Mistakidis, G. C. Katsimiga +5
Modulational instability (MI) is a fundamental phenomenon in the study of nonlinear dynamics, spanning diverse areas such as shallow water waves, optics, and ultracold atomic gases…
Observation of Momentum Space Josephson Effects
Annesh Mukhopadhyay, Xi-Wang Luo, Colby Schimelfenig +4
The momentum space Josephson effect describes the supercurrent flow between weakly coupled Bose-Einstein condensates (BECs) at two discrete momentum states. Here, we experimentally…
Observation of dense collisional soliton complexes in a two-component Bose-Einstein condensate
S. Mossman, G. C. Katsimiga, S. I. Mistakidis +5
Solitons are nonlinear solitary waves which maintain their shape over time and through collisions, occurring in a variety of nonlinear media from plasmas to optics. We present an e…
Lattice dynamics in an emergent Zeeman lattice
M. K. H. Ome, Huaxin He, A. Mukhopadhyay +5
Periodic band structures are a hallmark phenomenon of condensed matter physics. While often imposed by external potentials, periodicity can also arise through the interplay of coup…
Non-exponential tunneling due to mean-field induced swallowtails
Q. Guan, M. K. H. Ome, T. M. Bersano +3
Typically, energy levels change without bifurcating in response to a change of a control parameter. Bifurcations can lead to loops or swallowtails in the energy spectrum. The simpl…
Rabi oscillations and Ramsey-type pulses in ultracold bosons: Role of interactions
Q. Guan, T. M. Bersano, S. Mossman +2
Double-well systems loaded with one, two, or many quantum particles give rise to intriguing dynamics, ranging from Josephson oscillation to self-trapping. This work presents theore…
Observation and Analysis of Multiple Dark-Antidark Solitons in Two-Component Bose-Einstein Condensates
G. C. Katsimiga, S. I. Mistakidis, T. M. Bersano +6
We report on the static and dynamical properties of multiple dark-antidark solitons (DADs) in two-component, repulsively interacting Bose-Einstein condensates. Motivated by experim…
Experimental realization of a superfluid stripe phase in a spin-orbit-coupled Bose-Einstein condensate enabled by momentum-space hopping
Thomas M. Bersano, Junpeng Hou, Sean Mossman +5
In the past few decades, the search for supersolid-like phases has attracted great attention in condensed matter and ultracold atom communities. Here we experimentally demonstrate…
Momentum-Space Josephson Effects
Junpeng Hou, Xi-Wang Luo, Kuei Sun +5
The Josephson effect is a prominent phenomenon of quantum supercurrents that has been widely studied in superconductors and superfluids. Typical Josephson junctions consist of two…
