Complementary projection defects and decomposition

Journal of High Energy Physics, 2021
As put forward in [1] topological quantum field theories can be projected using so-called projection defects. The projected theory and its correlation functions can be completely realized within the unprojected one.

3 definitions of BF theory on homology 3-spheres

Journal of High Energy Physics, 2023
3-dimensional BF theory with gauge group G (= Chern-Simons theory with non-compact gauge group TG) is a deceptively simple yet subtle topological gauge theory.

How planar superconductors cure their infrared divergences

Journal of High Energy Physics, 2022
Planar superconductors, emerging in thin films with thickness comparable to the superconducting coherence length, differ crucially from their bulk counterparts.

Kink scattering in the presence of geometric constrictions

Journal of High Energy Physics, 2023
We investigate kink-antikink collisions in a model characterized by two scalar fields in the presence of geometric constrictions. The model includes an auxiliary function that modifies the kinematics associated with one of the two fields.

A note on entanglement edge modes in Chern Simons theory

Journal of High Energy Physics, 2018
We elaborate on the extended Hilbert space factorization of Chern Simons theory and show how this arises naturally from a proper regularization of the entangling surface in the Euclidean path integral.

Global 3-group symmetry and ’t Hooft anomalies in axion electrodynamics

Journal of High Energy Physics, 2021
We investigate a higher-group structure of massless axion electrodynamics in (3 + 1) dimensions. By using the background gauging method, we show that the higher-form symmetries necessarily have a global semistrict 3-group (2-crossed module) structure ...

Twisted massive non-compact models

Journal of High Energy Physics, 2018
We study interacting massive N = (2, 2) supersymmetric field theories in two dimensions which arise from deforming conformal field theories with a continuous spectrum.

TBA equations and resurgent Quantum Mechanics

Journal of High Energy Physics, 2019
We derive a system of TBA equations governing the exact WKB periods in one-dimensional Quantum Mechanics with arbitrary polynomial potentials. These equations provide a generalization of the ODE/IM correspondence, and they can be regarded as the solution

Homological classification of topological terms in sigma models on homogeneous spaces

Journal of High Energy Physics, 2018
We classify the topological terms (in a sense to be made precise) that may appear in a non-linear sigma model based on maps from an arbitrary worldvolume manifold to a homogeneous space G/H (where G is an arbitrary Lie group and H ⊂ G).

Effective Quantum Field Theory for the Thermodynamical Bethe Ansatz

Journal of High Energy Physics, 2020
We construct an effective Quantum Field Theory for the wrapping effects in 1+1 dimensional models of factorised scattering. The recently developed graph-theoretical approach to TBA gives the perturbative desctiption of this QFT.
