Scrambling dynamics and many-body chaos in a random dipolar spin model
Ahmet Keles, Erhai Zhao, W. Vincent Liu
Is there a quantum many-body system that scrambles information as fast as a black hole? The Sachev-Ye-Kitaev model can saturate the conjectured bound for chaos, but it requires ran…
Exactly Solvable Points and Symmetry-Protected Topological Phases of Quantum Spins on a Zig-Zag Lattice
Haiyuan Zou, Erhai Zhao, Xi-Wen Guan +1
A large number of symmetry-protected topological (SPT) phases have been hypothesized for strongly interacting spin-1/2 systems in one dimension. Realizing these SPT phases, however…
Induced -wave pairing in Bose-Fermi mixtures
Jami J. Kinnunen, Zhigang Wu, Georg M. Bruun
Cooper pairing caused by an induced interaction represents a paradigm in our description of fermionic superfluidity. Here, we present a strong coupling theory for the critical temp…
Dynamical detection of topological charges
Long Zhang, Lin Zhang, Xiong-Jun Liu
We propose a generic scheme to characterize topological phases via detecting topological charges by quench dynamics. A topological charge is defined as the chirality of a monopole…
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…
Resonant Spin Exchange between Heteronuclear Atoms Assisted by Periodic Driving
Jun-Jie Chen, Zhi-Fang Xu, Li You
We propose a general scheme for inducing resonant exchange between spins or pseudo-spins of unmatched levels via periodic driving. The basic idea is illustrated for a system of two…
Bosonic Topological Excitations from the Instability of a Quadratic Band Crossing
Guang-Quan Luo, Andreas Hemmerich, Zhi-Fang Xu
We investigate the interaction-driven instability of a quadratic band crossing arising for ultracold bosonic atoms loaded into a two-dimensional optical lattice. We consider the ca…
Dynamics and Density Correlations in Matter Wave Jet Emission of a Driven Condensate
Zhigang Wu, Hui Zhai
Emission of matter wave jets has been recently observed in a Bose-Einstein condensate confined by a cylindrical box potential, induced by a periodically modulated inter-particle in…
