My research focuses on strongly correlated quantum many-body systems, particularly highly frustrated magnets such as quantum spin liquids (QSLs). During my Ph.D., I theoretically investigated lattice defects in Kitaev spin liquids as experimentally accessible probes of spin fractionalization and explored novel phenomena driven by exotic fractional quasiparticles. I am now extending this research toward near-term quantum simulation, including the state preparation and dynamical evolution of QSLs on quantum computers, as well as HPC-based studies of spin systems using two-dimensional tensor-network methods.
