Self-dual U(1) lattice field theory with a θ-term
We study U(1) gauge theories with a modified Villain action. Such theories can naturally be coupled to electric and magnetic matter, and display...

Symmetry resolved entanglement of excited states in quantum field theory. Part I. Free theories, twist fields and qubits
The excess entanglement resulting from exciting a finite number of quasiparticles above the ground state of a free integrable quantum field theory...

Dualities between fermionic theories and the Potts model
We show that a large class of fermionic theories are dual to a q → 0 limit of the Potts model in the presence of a magnetic field. These can be...

Study of the Roberge-Weiss phase caused by external uniform classical electric field using lattice QCD approach
The effect of an external electric field on the quark matter is an important question due to the presence of strong electric fields in heavy ion...

On the renormalization of non-polynomial field theories
A class of scalar models with non-polynomial interaction, which naturally admits an analytical resummation of the series of tadpole diagrams is...

New supersymmetric string theories from discrete theta angles
We describe three previously unnoticed components of the moduli space of minimally supersymmetric string theories in d ≥ 7, describing in some detail...

Extrapolation from hypergeometric functions, continued functions and Borel-Leroy transformation; Resummation of perturbative renormalization functions from field theories
Physically relevant field-theoretic quantities are usually derived from perturbation techniques. These quantities are solved in the form of an...

Spectrum of large N glueballs: holography vs lattice
Recently there has been a notable progress in the study of glueball states in lattice gauge theories, in particular extrapolating their spectrum to...

Out-of-Time-Order correlators in driven conformal field theories
We compute Out-of-Time-Order correlators (OTOCs) for conformal field theories (CFTs) subjected to either continuous or discrete periodic drive...

Lattice Gauge Theories
According to present-day knowledge, all fundamental interactions in nature are described by gauge theories. The best known example is electrodynamics...

Finite volume form factors in integrable theories
We develop a new method to calculate finite size corrections for form factors in two-dimensional integrable quantum field theories. We extract these...

Electric field decay without pair production: lattice, bosonization and novel worldline instantons
Electric fields can spontaneously decay via the Schwinger effect, the nucleation of a charged particle-anti particle pair separated by a critical...

Probing non-perturbative supersymmetry breaking through lattice path integrals
We investigate non-perturbative supersymmetry breaking in various models of quantum mechanics, including an interesting class of PT -invariant models,...

Construction of two-dimensional topological field theories with non-invertible symmetries
We construct the defining data of two-dimensional topological field theories (TFTs) enriched by non-invertible symmetries/topological defect lines....

Compactifying 5d superconformal field theories to 3d
Building on recent progress in the study of compactifications of 6 d (1 , 0) superconformal field theories (SCFTs) on Riemann surfaces to 4 d

Entanglement and confinement in lattice gauge theory tensor networks
We develop a transfer operator approach for the calculation of Rényi entanglement entropies in arbitrary (i.e. Abelian and non-Abelian) pure lattice...
