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…
Entanglement Spectrum Crossings Reveal non-Hermitian Dynamical Topology
Sharareh Sayyad, Jinlong Yu, Adolfo G. Grushin +1
The development of non-Hermitian topological band theory has led to observations of novel topological phenomena in effectively classical, driven and dissipative systems. However, f…
Many-body topological invariants from randomized measurements
Andreas Elben, Jinlong Yu, Guanyu Zhu +4
The classification of symmetry-protected topological (SPT) phases in one dimension has been recently achieved, and had a fundamental impact in our understanding of quantum phases i…
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…
Stability of entanglement-spectrum crossing in quench dynamics of one dimensional gapped free-fermion systems
Shuangyuan Lu, Jinlong Yu
In a recent work by Gong and Ueda (arXiv:1710.05289), the classification of (1+1)-dimensional quench dynamics for the ten Altland-Zirnbauer classes is achieved, and entanglement-sp…
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

Using the recently developed Bloch-state tomography technique, the quasimomentum -dependent Bloch states ${\left( {\sin \left( {θ_{\mathbf{k}}/2} \right),\; - \cos \left( {θ…
Measuring Topological Number of a Chern-Insulator from Quench Dynamics
Ce Wang, Pengfei Zhang, Xin Chen +2
In this letter we show how the topological number of a static Hamiltonian can be measured from a dynamical quench process. We focus on a two-band Chern insulator in two-dimension,…
Generating topological optical flux lattices for ultracold atoms by modulated Raman and radio-frequency couplings
Jinlong Yu, Zhi-Fang Xu, Li You
We propose a scheme to dynamically generate optical flux lattices with nontrivial band topology using amplitude-modulated Raman lasers and radio-frequency (rf) magnetic fields. By…
Dynamical Generation of Topological Magnetic Lattices for Ultracold Atoms
Jinlong Yu, Zhi-Fang Xu, Rong Lü +1
We propose a scheme to dynamically synthesize a space-periodic effective magnetic field for neutral atoms by time-periodic magnetic field pulses. When atomic spin adiabatically fol…
