林本川 (Ben-Chuan LIN)

Dr. Lin’s research lies at the intersection of quantum materials, topological condensed-matter physics, and experimental superconductivity. He investigates emergent quantum states arising from the interplay among electronic band topology, unconventional superconducting pairing, spin–orbit coupling, and crystalline symmetry. A central objective of his work is to establish experimentally accessible criteria for identifying intrinsic topological superconductivity and distinguishing it from topological superconducting phenomena induced by interfaces, proximity effects, or device engineering. His research combines the discovery and characterization of candidate quantum materials with low-temperature measurements and systematic analyses of their superconducting and topological properties.

Dr. Lin’s current research interests focus on the search for intrinsic topological superconductors, particularly candidate $p$-wave superconducting materials, and on the development of robust experimental methodologies for diagnosing unconventional pairing and nontrivial superconducting topology. He is especially interested in identifying reproducible physical signatures that connect superconducting order-parameter symmetry, topological quasiparticle excitations, and material-specific electronic structures. More broadly, his work aims to construct an integrated experimental framework spanning material discovery, quantum-state characterization, and device-oriented investigations, with the long-term goal of elucidating the microscopic origin of topological superconductivity and assessing its potential relevance to fault-tolerant topological quantum computation.
