Jet Sub-structure in Fireworks Emission from Non-uniform and Rotating Bose-Einstein Condensates
Han Fu, Zhendong Zhang, Kai-Xuan Yao +5
We show that jet emission from a Bose condensate with periodically driven interactions, a.k.a. "Bose fireworks", contains essential information on the condensate wavefunction, whic…
Pattern formation in a driven Bose-Einstein Condensate
Zhendong Zhang, Kai-Xuan Yao, Lei Feng +2
Pattern formation is ubiquitous in nature from morphogenesis and cloud formation to galaxy filamentation. More often than not, patterns arise in a medium driven far from equilibriu…
Density waves and jet emission asymmetry in Bose Fireworks
Han Fu, Lei Feng, Brandon M. Anderson +5
A Bose condensate subject to a periodic modulation of the two-body interactions was recently observed to emit matter-wave jets resembling "fireworks" [Nature 551, 356(2017)]. In th…
Complex correlations in high harmonic generation of matter-wave jets revealed by pattern recognition
Lei Feng, Jiazhong Hu, Logan W. Clark +1
Correlations in interacting many-body systems are key to the study of quantum materials and quantum information. More often than not, the complexity of the correlations grows quick…
Observation of density-dependent gauge fields in a Bose-Einstein condensate based on micromotion control in a shaken two-dimensional lattice
Logan W. Clark, Brandon M. Anderson, Lei Feng +3
We demonstrate a density-dependent gauge field, induced by atomic interactions, for quantum gases. The gauge field results from the synchronous coupling between the interactions an…
Collective emission of matter-wave jets from driven Bose-Einstein condensates
Logan W. Clark, Anita Gaj, Lei Feng +1
Scattering is an elementary probe for matter and its interactions in all areas of physics. Ultracold atomic gases provide a powerful platform in which control over pair-wise intera…
Coherent inflationary dynamics for Bose-Einstein condensates crossing a quantum critical point
Lei Feng, Logan W. Clark, Anita Gaj +1
Quantum phase transitions, transitions between many-body ground states, are of extensive interest in research ranging from condensed matter physics to cosmology. Key features of th…
Floquet-Band Engineering of Shaken Bosonic Condensates
Brandon M. Anderson, Logan W. Clark, Jennifer Crawford +6
Optical control and manipulation of cold atoms has become an important topic in condensed matter. Widely employed are optical lattice shaking experiments which allow the introducti…
Universal space-time scaling symmetry in the dynamics of bosons across a quantum phase transition
Logan W. Clark, Lei Feng, Cheng Chin
The dynamics of many-body systems spanning condensed matter, cosmology, and beyond is hypothesized to be universal when the systems cross continuous phase transitions. The universa…
