Areas of Research Interests/ Research Projects

My research areas are theory of cold atomic gases and quantum matters in general. Our research on cold atom physics nearly covers all aspects of cold atom physics, mainly including:
1. Strongly interacting cold atomic gases: Few- and many-body problems nearby a Feshbach resonance, non-equilibrium problems.
2. Topological quantum matters: Spin-orbit coupling and synthetic gauge field in cold atom system, dynamicaland interaction effect in topological matters.
3. Quantum simulation with cold atoms in optical lattices: Bose and Fermi Hubbard model, quantum phase transition.
Other research interests on quantum matters include holographic quantum matter, Floquet system and machine learning.

Representative Papers:

1. Observation of the Efimovian Expansion in Scale-Invariant Fermi Gases
Shujin Deng, Zhe-Yu Shi, Pengpeng Diao, Qianli Yu, Hui Zhai, Ran Qi and Haibin Wu
Science, 335, 371 (2016)

Theoretically discover a new type of quantum many-body dynamics that obeys a discrete scaling symmetry in time, termed as “the Efimovian Expansion”. This predication is confirmed by an experiment of ECNU.

2. Orbital Feshbach Resonance in Alkali-Earth Atoms
Ren Zhang, Yanting Cheng, Hui Zhai and Peng Zhang
Physical Review Letters, 115, 135301 (2015)

Predict that alkaline-earth atom can possess a new type of magnetic-field tunable Feshbach resonance, through a new mechanismutilizing orbital degree of freedom, and name it as the “Orbital Feshbach Resonance”. This predication has been soon confirmed by two experiments from Munich and Florence groups.

3. Spin-Orbit Coupled Degenerate Fermi Gases,
Pengjun Wang, Zeng-Qiang Yu, Zhengkun Fu, Jiao Miao, Lianghui Huang, Shijie Chai, Hui Zhai and Jing Zhang,
Phys. Rev. Lett. 109, 095301 (2012)

In collaboration with the experimental group of Shanxi University, first experimentally realize and study spin-orbit coupled degenerate Fermi gas with cold atoms. SCI Citation >400.

4. Spin-Orbit Coupled Spinor Bose-Einstein Condensates
Chunji Wang, Chao Gao, Chao-Ming Jian and Hui Zhai
Physical Review Letters, 105, 160403 (2010)

First predict that the ground state of a spin-orbit Bose condensate exhibits stripe order, which has been confirmed by several experiments from the MIT and other groups. SCI Citation >250.

5. Functional Renormalization-Group Study of the Pairing Symmetry and Pairing Mechanism of the FeAs-Based High Temperature Superconductor
Fa Wang, Hui Zhai, Ying Ran, Ashvin Vishwanath and Dung-Hai Lee
Physical Review Letters, 102, 047005 (2009)

Predict the pairing symmetry of ion pnictide superconductor, which has been confirmed by quite a few experiments. SCI Citation >350.
