Cold Atom Physics

The-state-of-art laser cooling techniques help one easily collect a huge number (normally higher than a hundred million) of atoms at a very low temperature (tens of micro Kelvin), which offers a great opportunity for applications in precision spectroscopy, metrology, quantum memory of light, controlled cold collisions, etc. When atoms are cooled furthermore to zero-temperature with the so-called “evaporative cooling”, physics due to thermodynamics will be no longer applicable in describing these ultracold systems and instead quantum physics will dominantly govern the dynamics therein. These ultracold systems bring us ideal platforms for studying many-body physics in strong coupling regime, emulating a definite Hamiltonian, investigating quantum correlation and quantum fluctuation, and manipulating multipartite entanglement in an unprecedented way.

Within the Division of Quantum Physics and Quantum Information, HFNL, our research covers the following directions that are all based on cold/ultracold atoms,

Quantum simulation

Fermi-Fermi Mixture

Quantum memory and quantum repeater group

High Resolution Optical Lattices

Strontium Rydberg Atoms
