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…
Linking invariant for the quench dynamics of a two-dimensional two-band Chern insulator
Xin Chen, Ce Wang, Jinlong Yu
We discuss the topological invariant in the (2+1)-dimensional quench dynamics of a two-dimensional two-band Chern insulator starting from a topological initial state (i.e., with a…
On the Equivalence between Spin and Charge Dynamics of the Fermi Hubbard Model
Hui Zhai, Ning Sun, Jinlong Yu +1
Utilizing the Fermi gas microscope, recently the MIT group has measured the spin transport of the Fermi Hubbard model starting from a spin-density-wave state, and the Princeton gro…
Measuring Hopf links and Hopf invariants in a quenched topological Raman lattice
Jinlong Yu
In a recent experimental work [Z. Wu et al., Science 354, 83 (2016)], the PKU-USTC group realized a two-dimensional two-band quantum anomalous Hall model on a square Raman lattice.…
Symmetry Protected Dynamical Symmetry in the Generalized Hubbard Models
Jinlong Yu, Ning Sun, Hui Zhai
In this letter we present a theorem on the dynamics of the generalized Hubbard models. This theorem shows that the symmetry of the single particle Hamiltonian can protect a kind of…
Phase vortices of the quenched Haldane Model
Jinlong Yu
Using the recently developed Bloch-state tomography technique, the quasimomentum -dependent Bloch states ${\left( {\sin \left( {θ_{\mathbf{k}}/2} \right),\; - \cos \left( {θ…
