Our research lies in the theoretical study of quantum transport across topological, magnetic, and superconducting systems, with a dedicated focus on magnetic topological matter, unconventional antiferromagnets, Josephson physics, and open quantum systems.
We explore quantum transport in topological materials with an emphasis on the interplay among magnetic fields, finite-size effects, and boundary-state hybridization. Particular attention is devoted to transport signatures of nontrivial topology, including quantum oscillations, nonlocal transport, and quantum interference in topological insulators and semimetals.
We investigate the interplay between topology and magnetism in intrinsic magnetic topological materials, particularly antiferromagnetic topological insulators such as MnBi2Te4. Current interests include topological surface and hinge states, finite-size hybridization, axion and higher-order topological phases, as well as electrically controlled transport based on layer degrees of freedom.
We study phase-coherent transport in Josephson junctions where superconductivity couples to unconventional magnetism. The focus lies on how altermagnetism and chiral antiferromagnetism modify Andreev processes, superconducting pairing, current-phase relations, and 0-π transitions, together with how environmental coupling reshapes Andreev spectra and Josephson transport in open quantum systems.
