Extracting the Quantum Geometric Tensor of an Optical Raman Lattice by Bloch State Tomography
Chang-Rui Yi, Jinlong Yu, Huan Yuan +6
In Hilbert space, the geometry of the quantum state is identified by the quantum geometric tensor (QGT), whose imaginary part is the Berry curvature and real part is the quantum me…
Tuning anomalous Floquet topological bands with ultracold atoms
Jin-Yi Zhang, Chang-Rui Yi, Long Zhang +7
The Floquet engineering opens the way to create new topological states without counterparts in static systems. Here, we report the experimental realization and characterization of…
Realization of ideal Weyl semimetal band in ultracold quantum gas with 3D Spin-Orbit coupling
Zong-Yao Wang, Xiang-Can Cheng, Bao-Zong Wang +8
The Weyl semimetals [1-6] are three-dimensional (3D) gapless topological phases with Weyl cones in the bulk band, and host massless quasiparticles known as Weyl fermions which were…
Experimental Determination of the Finite-Temperature Phase Diagram of a Spin-Orbit Coupled Bose Gas
Si-Cong Ji, Jin-Yi Zhang, Long Zhang +6
Spin-orbit (SO) coupling has led to numerously exciting phenomena in electron systems, for instance, the recently discovered topological insulator. The synthesized SO coupling with…
Stability of Excited Dressed States with Spin-Orbit Coupling
Long Zhang, Jin-Yi Zhang, Si-Cong Ji +6
We study the decay behaviors of ultracold atoms in metastable states with spin-orbit coupling (SOC), and demonstrate that there are two SOC-induced decay mechanisms. One arises fro…
Collective Dipole Oscillation of a Spin-Orbit Coupled Bose-Einstein Condensate
Jin-Yi Zhang, Si-Cong Ji, Zhu Chen +9
We present an experimental study of the collective dipole oscillation of a spin-orbit coupled Bose-Einstein condensate in a harmonic trap. Dynamics of the center-of-mass dipole osc…
