Atomic Physics and Optical Science
The Atomic Physics and Optical Science Group consists of 5 Research Fellows and 2 adjunct Research Fellows. The research fields cover: (1) Quantum optics and quantum information science based on cold atoms and solid-state spins in diamond. (2) Quantum computing and simulation based on Rydberg-interacting neutral atoms. (3) Atomic physics for quantum metrology, continuous atom laser and continuous optical clock. (4) Atom interferometer and quantum control of atoms in optical lattices. (5) Theoretical and experimental studies on ultracold atomic gases, including superfluidity, synthetic gauge fields, and spinor condensates.
Ying-Cheng Chen is working on the optical quantum memory based on electromagnetically induced transparency with cold atomic media, as well as its application to quantum information science. He is also studying the cooperative radiation phenomena such as superradiance and subradiance with optically dense cold atomic media. Ying-Cheng Chen also collaborates with Yu-Ju Lin, Hsiang-Hua Jen, and Yang-Hao Chan on a joint project to realize quantum computing and simulation with Rydberg-interacting neutral atoms. Ming-Shien Chang and Yu-Ju Lin are working on experiments of ultracold quantum gases. Ming-Shien Chang focuses his study on the investigation of quantum dynamics and quantum phases of spinor condensates, while Yu-Ju Lin is investigating spin-orbital-angular-momentum coupling with synthetic gauge potentials. Ming-Shien Chang also collaborates with Huan-Cheng Chang and Hsiang-Hua Jen on the quantum sensing and quantum optics utilizing ground states spins of nitrogen vacancy centers in fluorescent nanodiamonds. Chun-Chia Chen is developing quantum control techniques that utilize ultranarrow-linewidth clock transitions to realize continuous quantum gases. His work is aimed at advancing coherent-matter-wave devices, which are essential for next-generation quantum metrology and precision measurement studies. Hsiang-Hua Jen focuses on the theoretical studies of the cooperative spontaneous emissions, chiral quantum interface, and multipartite entanglement generations. He is also working on the photon-mediated dipole-dipole interactions on light scattering in dense cold atoms and non-Hermitian physics in an optical atomic mirror. Shayne Bennetts uses optical nanofibers to couple individually controlled ytterbium atom arrays, building a platform for quantum research and next-generation devices. His work aims to pave the way towards integrated atom-nanophotonic chips, quantum processors, and sensors. Alongside Chun-Chia Chen, he is also developing continuous atom lasers and superradiant active optical clocks.
The adjunct faculty, Sungkit Yip is devoted to theoretical investigations of superconductivity and ultra-cold atomic gases, especially multi-component bosonic and fermionic systems, superfluidity and pairing in fermionic atoms, quantum magnetism in optical lattices and other strongly correlated phenomena. He is in collaboration with Yu-Ju Lin and Ming-Shien Chang.
The adjunct faculty, Shau-Yu Lan, focuses on advancing applications of atomic interferometry in fundamental physics, quantum sensing, and inertial navigation, working to unlock new possibilities for these cutting-edge technologies. Additionally, Professor Lan investigates the quantum control of atoms in optical lattices, aiming to explore core issues in continuous-variable quantum information processing and many-body physics. He is in collaboration with Ying-Cheng Chen, Ming-Shien Chang, and Yu-Ju Lin.
