Observing the two-dimensional Bose glass in an optical quasicrystal
Jr-Chiun Yu, Shaurya Bhave, Lee Reeve +2
The combined effect of disorder and interactions is central to the richness of condensed matter physics and can lead to novel quantum states such as the Bose glass phase in disorde…
Geometric pumping and dephasing at topological phase transition
B. Q. Song, J. D. H. Smith, L. Luo +1
A measure-preserving formalism (MPF) is constructed and applied to spin/band models, which yield observations about pumping. It occurs at topological phase transition (TPT), i.e.,…
Realizing discontinuous quantum phase transitions in a strongly-correlated driven optical lattice
Bo Song, Shovan Dutta, Shaurya Bhave +4
Discontinuous quantum phase transitions and the associated metastability play central roles in diverse areas of physics ranging from ferromagnetism to false vacuum decay in the ear…
Effective statistical fringe removal algorithm for high-sensitivity imaging of ultracold atoms
Bo Song, Chengdong He, Zejian Ren +3
High-sensitivity imaging of ultracold atoms is often challenging when interference patterns are imprinted on the imaging light. Such image noises result in low signal-to-noise rati…
Evidence for Bosonization in a three-dimensional gas of SU() fermions
Bo Song, Yangqian Yan, Chengdong He +3
Blurring the boundary between bosons and fermions lies at the heart of a wide range of intriguing quantum phenomena in multiple disciplines, ranging from condensed matter physics a…
Collective excitations in two-dimensional SU() Fermi gases with tunable spin
Chengdong He, Zejian Ren, Bo Song +5
We measure collective excitations of a harmonically trapped two-dimensional (2D) SU() Fermi gas of Yb confined to a stack of layers formed by a one-dimensional optical l…
Collective dipole oscillations of a spin-orbit coupled Fermi gas
Shanchao Zhang, Chengdong He, Elnur Hajiyev +3
The collective dipole mode is induced and measured in a spin-orbit (SO) coupled degenerate Fermi gas of Yb atoms. Using a differential optical Stark shift, we split the deg…
Observation of nodal-line semimetal with ultracold fermions in an optical lattice
Bo Song, Chengdong He, Sen Niu +4
Observation of topological phases beyond two-dimension (2D) has been an open challenge for ultracold atoms. Here, we realize for the first time a 3D spin-orbit coupled nodal-line s…
Observation of symmetry-protected topological band with ultracold fermions
Bo Song, Long Zhang, Chengdong He +5
Symmetry plays a fundamental role in understanding complex quantum matter, particularly in classifying topological quantum phases, which have attracted great interests in the recen…
Spin-orbit coupled two-electron Fermi gases of ytterbium atoms
Bo Song, Chengdong He, Shanchao Zhang +4
We demonstrate all-optical implementation of spin-orbit coupling (SOC) in a two-electron Fermi gas of Yb atoms by coupling two hyperfine ground states with a narrow optical…
