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…
Observing topological charges and dynamical bulk-surface correspondence with ultracold atoms
Chang-Rui Yi, Long Zhang, Lin Zhang +8
In quenching a topological phase across phase transition, the dynamical bulk-surface correspondence emerges that the bulk topology of -dimensional (D) phase relates to the no…
Observation of the Hopf Links and Hopf Fibration in a 2D topological Raman Lattice
Chang-Rui Yi, Jin-Long Yu, Wei Sun +3
A dynamical Hopf insulator is experimentally synthesized with a quenched two-dimensional quantum anomalous Hall system on a square Raman lattice. The quench dynamics for the quasim…
Ultra-low noise magnetic field for quantum gases
Xiao-Tian Xu, Zong-Yao Wang, Rui-Heng Jiao +3
Ultra-low noise magnetic field is essential for many branches of scientific research. Examplesinclude experiments conducted on ultra-cold atoms, quantum simulations, as well as pre…
