Field theory and quantum criticality in lattice systems
My research uses conformal and quantum field theory to understand universal phenomena in quantum many-body systems. My work centers on boundary criticality, quantum-information measures of many-body states, and universal data and dynamics in nonunitary and non-Hermitian systems.
Research Themes
Boundary CFT and quantum criticality
I use boundary conformal field theory and conformal perturbation theory to study boundary conditions and boundary renormalization-group flows in microscopic quantum chains. Numerical results from collaborators provide complementary tests of these analytical predictions. This includes finite-size corrections in gapless one-dimensional systems and boundary criticality in the quantum Ashkin-Teller model. I am also exploring broader applications of boundary field-theoretic ideas to critical systems with modulated structures.
Quantum information and entanglement diagnostics
I study quantum-information and entanglement-based probes of how universal continuum behavior emerges from microscopic many-body states. In collaborative projects, tensor-network calculations performed by collaborators provide complementary numerical tests of field-theoretic predictions. Current work examines connections between generalized quantum measurements and boundary phenomena in critical systems.
Non-Hermitian critical phenomena and dynamics
My recent work develops a boundary-CFT framework for biorthogonal global quenches in interacting non-Hermitian critical systems, in which complex temporal-boundary data organize universal post-quench dynamics. This complements my work on extracting boundary conformal data from periodic non-Hermitian critical chains.
