Topological Field Theory and Nonlinear $\sigma$-Models on Symmetric Spaces

, 1995
We show that the classical non-abelian pure Chern-Simons action is related to nonrelativistic models in (2+1)-dimensions, via reductions of the gauge connection in Hermitian symmetric spaces.

Topological Valley Photonic Waveguides: Scattering Matrix Evaluation for Linear Computing

Advanced Photonics Research, Volume 6, Issue 11, November 2025.
This research is focused on the design of a 6‐port junction via valley photonic crystal waveguides to achieve equal power splitting of an incident signal towards three other ports. An in‐depth study is carried out to extract its corresponding scattering matrix.

Sign Competing Sources of Berry Curvature and Anomalous Hall Conductance Humps in Topological Ferromagnets

Advanced Electronic Materials, Volume 11, Issue 18, November 4, 2025.
Mechanism proposed for the humps in topological ferromagnet. a) Hysteresis loops of σxy in external uniaxial magnetic field Hz and b) Anomalous Hall conductivity σxy as a function of polar angle θ. Data for |h⃗|$|\vec{h}|$ = 3t and λR/t = 0.08. A, B, and C are the states of the 2D topological ferromagnets.

Narain CFTs from quantum codes and their $${\mathbb{Z}}_{2}$$ gauging

Journal of High Energy Physics
We investigate the gauging of a $${\mathbb{Z}}_{2}$$ symmetry in Narain conformal field theories (CFTs) constructed from qudit stabilizer codes. Considering both orbifold and fermionization, we establish a connection between $${\mathbb{Z}}_{2}$$ gauging ...
