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…
Fulde-Ferrell-Larkin-Ovchinnikov pairing states of a polarized dipolar Fermi gas trapped in a one-dimensional optical lattice
Xingbo Wei, Chao Gao, Reza Asgari +2
We study the interplay between the long- and short-range interaction of a one-dimensional optical lattice system of two-component dipolar fermions by using the density matrix renor…
Revealing the origin of super-Efimov states in the hyperspherical formalism
Chao Gao, Jia Wang, Zhenhua Yu
Super-Efimov states are a new kind of universal three-body bound states predicted for three identical fermions with -wave resonant interactions in two dimensions by a recent fie…
The third virial coefficient of a two-component unitary Fermi gas across an Efimov-effect threshold
Chao Gao, Shimpei Endo, Yvan Castin
We consider a mixture of two single-spin-state fermions with an interaction of negligible range and infinite -wave scattering length. By varying the mass ratio across $α_c\s…
Three Identical Fermions with Resonant p-wave Interactions in Two Dimensions
Chao Gao, Zhenhua Yu
A new kind of "super-Efimov" states of binding energies scaling as were predicted by a field theory calculation for three fermions with resonant -wave i…
Breathing mode of two-dimensional atomic Fermi gases in harmonic traps
Chao Gao, Zhenhua Yu
For two-dimensional (2D) atomic Fermi gases in harmonic traps, the SO(2,1) symmetry is broken by the interatomic interaction explicitly via the contact correlation operator. Conseq…
Spin-Orbit Coupled Spinor Bose-Einstein Condensates
Chunji Wang, Chao Gao, Chao-Ming Jian +1
An effective spin-orbit coupling can be generated in cold atom system by engineering atom-light interactions. In this letter we study spin-1/2 and spin-1 Bose-Einstein condensates…
