Current Research:

The research program in our group is focused on the physics of unconventional electronic structures in solid state materials. In particular, we explore new quasiparticle ground states that are emerged due to competing phase orders and/or electron correlations in material heterostructures. The current research interests are placed on triplet (or p-wave) pairing in new superconductor heterostructures, the coexistence between superconductivity and ferromagnetism, and superconducting spintronics with the aim of implementing them in fault tolerant quantum computations. Our lab features molecular beam epitaxy (MBE) technique that allows the precise control of various material interfaces down to the atomic scale under clean ultra-high vacuum (UHV) environment. The integrated MBE-Ion Milling cluster chamber further provides a unique avenue on fabricating nanoscale hybrid devices, where mesoscopic physics of the unknown quasiparticles can be investigated in lower dimensions. Besides, quantum coherent tunneling spectroscopy, Josephson tunneling, as well as spin dependent electrical transport are utilized in our group in probing the new electronic structures.
