Research 

To discover and understand novel physical phenomena in condensed matter systems by utilizing measurements of thermal and transport properties, as well as soft point-contact spectroscopy, under a variety of extreme conditions—including 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. 

Pairing Mechanisms of Unconventional Superconductivity
Investigation of topological and heavy-fermion superconductors, with a particular focus on the superconducting gap structure near quantum critical points (QCPs).

Quantum Spin Liquids (QSLs) and Frustrated Magnetism
Exploration of exotic magnetic states in geometrically frustrated systems and development of novel experimental approaches to detect and characterize QSLs and their potential applications.

Quantum Materials
Study of heavy fermion compounds (HF), transition metal dichalcogenides (TMDCs), quantum spin liquid candidates (QSLs), and high-temperature superconductors (HTSCs).

Experimental Techniques and Instrumentation
Development and application of low-temperature experimental tools—including thermal, transport, and point-contact spectroscopy—to probe emergent physical phenomena under extreme conditions (high magnetic fields, high pressures, and ultra-low temperatures).

Transport and Thermodynamic Measurements:

• Electrical resistivity and Hall effect

• Thermal conductivity in rotating magnetic fields

• Specific heat as a function of temperature and magnetic field

• Magneto-caloric effect

• Soft-point contact spectroscopy and data analysis
  
  

High-Pressure Experiments (up to ~10 GPa):

• Cylinder piston-type pressure cell

• Indenter-type pressure cell
  
  

Low-Temperature and High Magnetic Field Techniques:

• Measurements down to ~1 mK and up to 16 T

Systems: PPMS, Oxford Heliox, Kelvinox, and custom-built ³He and ³He/⁴He dilution refrigerators
Magnets: Oxford Instruments and American Superconductor DC magnets

High Pulsed Magnetic Field Experiments:

• Up to 80 T with ultra-fast sweeping rates (~10,000 T/s)

Magnetic-field-dependent heat capacity measurements are carried out on an ultrapure sample of the UTe2 superconductor along different crystallographic directions. By analyzing the resulting field-dependent residual Sommerfeld coefficients, a case is made that 𝐵2⁢𝑢 is the primary superconducting order parameter in UTe2.
