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…
Observation of Laughlin states made of light
Logan W. Clark, Nathan Schine, Claire Baum +2
Much of the richness in nature emerges because the same simple constituents can form an endless variety of ordered states. While many such states are fully characterized by their s…
Probing gravity by holding atoms for 20 seconds
Victoria Xu, Matt Jaffe, Cristian D. Panda +3
Atom interferometers are powerful tools for both measurements in fundamental physics and inertial sensing applications. Their performance, however, has been limited by the availabl…
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…
Interacting Floquet polaritons
Logan W. Clark, Ningyuan Jia, Nathan Schine +3
Ordinarily, photons do not interact with one another. However, atoms can be used to mediate photonic interactions, raising the prospect of forming synthetic materials and quantum i…
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…
A Strongly Interacting Polaritonic Quantum Dot
Ningyuan Jia, Nathan Schine, Alexandros Georgakopoulos +3
Polaritons are an emerging platform for exploration of synthetic materials [1] and quantum information processing [2] that draw properties from two disparate particles: a photon an…
Calibrating High Intensity Absorption Imaging of Ultracold Atoms
Klaus Hueck, Niclas Luick, Lennart Sobirey +5
Absorption imaging of ultracold atoms is the foundation for quantitative extraction of information from experiments with ultracold atoms. Due to the limited exposure time available…
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…
Exotic domain walls in Bose-Einstein condensates with double-well dispersion
Tongtong Liu, Logan W. Clark, Cheng Chin
We study the domain walls which form when Bose condensates acquire a double-well dispersion. Experiments have observed such domain walls in condensates driven across a $\mathbb{Z}_…
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…
Quantum dynamics with spatiotemporal control of interactions in a stable Bose-Einstein condensate
Logan W. Clark, Li-Chung Ha, Chen-Yu Xu +1
Optical control of atomic interactions in a quantum gas is a long-sought goal of cold atom research. Previous experiments have been hindered by short lifetimes and parasitic deform…
Roton-Maxon Excitation Spectrum of Bose Condensates in a Shaken Optical Lattice
Li-Chung Ha, Logan W. Clark, Colin V. Parker +2
We present experimental evidence showing that an interacting Bose condensate in a shaken optical lattice develops a roton-maxon excitation spectrum, a feature normally associated w…
