Representative Papers:

1. Non-Hermitian Linear Response

Establish a generalized Kubu formula to probe many-body correlations through dissipation, named “non-Hermitian Linear response theory” [Nat. Phys. 2020].

2. Out-of-Time-Ordered Correlation

Propose and Prove a theorem that relates out-of-time-ordered correlation and the entanglement entropy dynamics [Sci. Bull 2017, citation > 170]. Collaborated with the USTC group, perform one of the first two experimental measurements of the out-of-time-ordered correlator [PRX 2017, citation>260].

3. Non-Equilibrium Topological Effect

Propose a method to realize the topological Haldane model using shaking optical lattice [PRA 2014, citation > 110]. The same method has been used later by the ETH group, realizing the Haldane model with cold atoms. Propose a scheme to detect the topological number of a Hamiltonian in quench dynamics [PRL 2017, citation > 105], which has been observed experimentally by the Hamburg group.

4. Scale Invariant Quantum Fluids

Predict a quantum dynamics with discrete scaling symmetry in the time domain in scale invariant quantum fluids, named “ Efimivan Expansion ”, which has been observed by the ECNU group [Science 2016]. Discover a set of new exact solution for hydrodynamic equations of scale invariant quantum fluids [PRX 2021].

5. Orbital Feshbach Resonance

Predict a novel type of Feshbach resonance in alkaline-earth atoms. This novel mechanism ultilizes the orbital degree of freedoms to replace the role of electronic spins in conventional magnetic Feshbach resonance, therefore, it is named “ orbital Feshbach resonance” [PRL 2015, citation 102]. This novel Feshbach resonance has been observed by both Munich and Florence groups.

6. Repulsive Polarons

Discover a novel type of elementary excitation, known as the repulsive polaron, in fermionic atomic gases [PRA 2010, citation 102]. This polaron has been observed by the Cambridge group. Later the Florence group has measured its energy, in good agreement with this prediction.

7. Spin-Orbit Coupled Cold Atomic Gases

Predict stripe superfluid in spin-orbit coupled Bose-Einstein condensate [PRL 2010, citation > 520], experimentally observed by the MIT group later. Collaborated with the Shanxi University group, first experimentally realized spin-orbit coupled Fermi gas [PRL 2012, citation 780].

8. Pairing Symmetry of Iron Pnictides

Predict the pairing symmetry of superconducting phase in iron pnictides [PRL 2009, citation > 410], confirmed by later experiments.
