$SO/Sp$ Chern-Simons Gauge Theories At Large $N$, $SO/Sp$ Penner Models And The Gauge Group Volumes
, 2012 We construct a deformed $SO/Sp$ Penner generating function responsible for the close connection between $SO/Sp$ Chern-Simons gauge theories at large $N$ and the $SO/Sp$ Penner models.

Advanced Materials, EarlyView.In this work, nonzero Berry curvature in photonic crystals is induced by breaking unit cell inversion symmetry through spatial shifts rather than geometrical modifications. This enables the design of ultraconfined topological states with subwavelength in‐plane field confinement and out‐of‐plane field isolation.

Fermi gas formalism for D-type quiver Chern-Simons theory with non-uniform ranks
Journal of High Energy PhysicsWe construct the Fermi gas formalism for the partition function of supersymmetric Chern-Simons theories with affine D-type quiver diagrams with non-uniform ranks of the gauge groups and Fayet-Illiopoulos parameters by two different approaches: the open ...

Reconfigurable Magnetotransport in MnBi2Te4 via Gate and Magnetic Field Tuning
Advanced Materials, EarlyView.Gate‐tunable magnetoresistance sign reversal under in‐plane magnetic fields is observed in an ultrathin MnBi2Te4 device, arising from spin reorientation and distinct scattering mechanisms. Moreover, angular‐dependent measurements reveal clear gate‐controlled magnetotransport anisotropy, underscoring the strong coupling between gating, spin ...

Non-Abelian fractional quantum Hall states and chiral coset conformal field theories
, 2000 We propose an effective Lagrangian for the low energy theory of the Pfaffian states of the fractional quantum Hall effect in the bulk in terms of non-Abelian Chern-Simons (CS) actions.

Advanced Optical Materials, EarlyView.This work quantifies chirality through the continuous chirality measure (CCM). The CCM is correlated to a variety of properties: spin‐orbit field, orbital angular momentum, circular dichroism, absorption dissymmetry factor (gCD) and the circular photogalvanic effect.

Fivebranes and 3-manifold homology
Journal of High Energy Physics, 2017 Motivated by physical constructions of homological knot invariants, we study their analogs for closed 3-manifolds. We show that fivebrane compactifications provide a universal description of various old and new homological invariants of 3-manifolds.

Berry Phases, Quantum Phase Transitions and Chern Numbers
, 2007 We study the relation between Chern numbers and Quantum Phase Transitions (QPT) in the XY spin-chain model. By coupling the spin chain to a single spin, it is possible to study topological invariants associated to the coupling Hamiltonian.

Methodology for Topological Interface Engineering in 2D Photonic Crystals
Advanced Photonics Research, EarlyView.This article introduces an automated framework for topological photonic crystal design. It features an iterative band connection method for identifying band crossings, a data‐driven approach for band symmetry recognition, and analysis of how topological mode dispersion trades off with photonic band‐gap size.
