Areas of Interest/Research

My research focuses on the pairing mechanisms of unconventional superconductivity, particularly in topological and heavy-fermion superconductors. I am interested in understanding the evolution of the superconducting gap structure near quantum critical points (QCPs), where strong electronic correlations and competing orders give rise to novel quantum phenomena.

In parallel, I explore quantum spin liquids (QSLs) and frustrated magnetism in geometrically frustrated systems. My work aims to develop and employ novel experimental techniques to detect and characterize QSL states, while also investigating their potential implications for emergent quantum functionalities.

More broadly, my research encompasses a variety of quantum materials, including heavy-fermion compounds (HF), transition metal dichalcogenides (TMDCs), quantum spin liquid candidates, and high-temperature superconductors (HTSCs). To probe these systems, I develop and apply low-temperature experimental methods—such as thermal and transport measurements and point-contact spectroscopy—under extreme conditions of high magnetic fields, high pressures, and ultra-low temperatures.

Recently, I have become particularly interested in advancing experimental techniques capable of accessing the “1–100 mK” regime, including transport and thermodynamic measurements optimized for ultralow temperatures. By integrating these capabilities with the High B/T facility at the National High Magnetic Field Laboratory (NHMFL), I aim to precisely investigate new physical properties that emerge in extreme cryogenic environments and to push the boundaries of correlated-electron research.  Through these efforts, I aim to uncover new emergent phenomena and deepen our understanding of correlated electron systems.
