Overview of Academic Research
The Nano-Probe Laboratory for Quantum Materials (NPQM Lab) is dedicated to nanoscale investigation and control of emergent quantum phenomena in quantum materials. By leveraging advanced scanning probe techniques, including low-temperature scanning tunneling microscopy (STM) and scanning near-field optical microscopy (SNOM), the lab enables atomic-scale imaging, spectroscopy, and in-situ manipulation of electronic and optical states.
Our research centers on high-temperature and topological superconductors, with a focus on emergent quantum states such as pair density waves, vortex lattices, topological edge modes, Majorana zero modes, nanoscale phase separation, and polaritonic excitations. In particular, we aim to visualize and engineer topological superconducting phases and Majorana-like quasiparticles at the atomic scale, providing experimental foundations for non-Abelian statistics and fault-tolerant topological qubits. Through an integrated framework of probing, control, and device construction, the lab seeks to bridge microscopic quantum phenomena with macroscopic quantum functionalities, supporting the advancement of topological quantum computing and energy-efficient quantum devices.
