Topological phases and edge modes of an uneven ladder
Wen-Chuang Shang, Yi-Ning Han, Shimpei Endo +1
We investigate the topological properties of a two-chain quantum ladder with uneven legs, i.e. the two chains differ in their periods by a factor of two. Such an uneven ladder pres…
Dynamical nonlinear excitations induced by interaction quench in a two-dimensional box-trapped Bose-Einstein condensate
Zhen-Xia Niu, Chao Gao
Manipulating nonlinear excitations, including solitons and vortices, is an essential topic in quantum many-body physics. A recent progress in this direction is a new protocol propo…
Ideal-Gas Approach to Hydrodynamics
Zhe-Yu Shi, Chao Gao, Hui Zhai
Transport is one of the most important physical processes in all energy and length scales. Ideal gases and hydrodynamics are, respectively, two opposite limits of transport. Here,…
Dynamical Fractal in Quantum Gases with Discrete Scaling Symmetry
Chao Gao, Hui Zhai, Zhe-Yu Shi
Inspired by the similarity between the fractal Weierstrass function and quantum systems with discrete scaling symmetry, we establish general conditions under which the dynamics of…
Universal Dynamics of a Degenerate Bose Gas Quenched to Unitarity
Chao Gao, Mingyuan Sun, Peng Zhang +1
Motivated by an unexpected experimental observation from the Cambridge group, [Eigen {\it et al.,} Nature {\bf563}, 221 (2018)], we study the evolution of the momentum distribution…
Steady-state phase diagram of quantum gases in a lattice coupled to a membrane
Chao Gao, Zhaoxin Liang
In a recent experiment [Vochezer {\it et al.,} Phys. Rev. Lett. \textbf{120}, 073602 (2018)], a novel kind of hybrid atom-opto-mechanical system has been realized by coupling atoms…
