Observing a topological phase transition with deep neural networks from experimental images of ultracold atoms

Entong Zhao, Ting Hin Mak, Chengdong He +4

Although classifying topological quantum phases have attracted great interests, the absence of local order parameter generically makes it challenging to detect a topological phase…

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…
