I am a researcher in experimental condensed matter physics with a strong focus on the growth and study of quantum magnetic materials. My expertise lies in single-crystal growth, X-ray diffraction, and a variety of low-temperature measurements (magnetization, heat capacity, and transport).
My research is centered on understanding novel magnetic ground states in frustrated magnets and correlated electron systems, particularly in compounds where the crystal structure itself drives unconventional physics. A major part of my work focuses on:
One-dimensional zigzag spin-1/2 chains, where reduced dimensionality and frustration can stabilize exotic ground states.
Hexagonal perovskites containing face-sharing CoO₆, MnO₆, and RuO₆ octahedra, forming dimers and trimers that host unusual quantum magnetic phenomena.
Exploration of localized versus itinerant electronic behavior and the role of molecular orbital formation or orbital-selective Mott states in shaping the low-energy physics.
Through this lens, I investigate how geometric frustration, orbital degrees of freedom, and disorder/defects (such as cation mixing or oxygen vacancies) interplay to produce emergent phases such as quantum spin liquids, spin-glass states, and orbital-selective correlated phases.
I actively collaborate with groups using advanced probes such as neutron scattering and muon spin rotation (µSR) to complement bulk measurements, aiming to provide a comprehensive understanding of spin correlations and low-energy excitations.
Crystal growth and magnetic characterization of zigzag spin-1/2 chain compounds such as ACoV₂O₇ (A = Ca, Sr, Zn).
Discovery of cluster spin-glass behavior in disordered cobalt-based hexagonal perovskites.
Growth of single crystals of ZnCoP₂O₇, revealing long-range antiferromagnetic order below ~3 K.
Investigations of Ba₃SbCo₂O₉ and related hexagonal perovskites, highlighting the role of Co–Co dimers in correlated electron states.
My broader goal is to unravel the interplay between structure, orbital physics, and magnetism in low-dimensional and frustrated systems. By connecting crystal chemistry, local electronic structure, and many-body physics, I aim to discover and understand novel correlated phases that could form the basis for new paradigms in quantum magnetism.
