Chiral gauge theories and their applications [PDF]

, 1998
This thesis is concerned with so called chiral gauge theories, also known as self dual gauge theories. In particular, the aim of this thesis to investigate the role that chiral gauge theories play in duality symmetries in lower dimensions through ...

A note on non-Lorentzian duality symmetries

Journal of High Energy Physics
We work out non-Lorentzian dual actions for electromagnetism and linearised gravity, both in the Carrollian and Galilean cases. This is done in the same way as for Lorentzian theories, by first constructing a parent action that reduces to a pair of dual ...

Extra dimensions and inflation

, 1999
It has been proposed that, without invoking supersymmetry, it is possible to solve the hierarchy problem provided the fundamental scale in the higher dimensional theory is at a much lower scale than the Planck scale. In this paper we consider a toy model

Canonical coordinates for Yang-Mills-Chern-Simons theory

Journal of High Energy Physics
We consider the classical field theory of 2+1-dimensional Yang-Mills-Chern-Simons theory on an arbitrary spatial manifold. We first define a gauge covariant transverse electric field strength, which together with the gauge covariant scalar magnetic field

Non-local tails in radiation in odd dimensions

, 2023
Huygens principle violation in a spacetime of odd dimensions leads to the fact that the retarded massless fields of localised sources depend on their history of motion preceding the retarded time. This non-local character of retarded fields should result

Vanishing Dimensions in Four Dimensional Cosmology with Nonminimal Derivative Coupling of Scalar Field

, 2014
We discussed a mechanism that allows the universe to start from lower dimension (d < 4) in its very early era and evolves to four dimension at the end of the process.

Lower-Form Symmetries

, 2022
When gauging a $(d-1)$-form symmetry in $d$ spacetime dimensions, one formally expects the gauged theory to carry a dual $-1$-form symmetry. This work focuses on the study of such symmetries, in particular via the spacetime-filling topological operators ...

Extended duality symmetries in theories of gravity

This thesis aims to shed a bit more light on the hidden duality symmetries in theories of gravity. It is well-known that these symmetries are manifest upon compactification to lower dimensions, and in low enough dimensions they are described by infinite ...

Modular Hamiltonian in the semi infinite line. Part II. Dimensional reduction of Dirac fermions in spherically symmetric regions

Journal of High Energy Physics
In this article, we extend our study on a new class of modular Hamiltonians on an interval attached to the origin on the semi-infinite line, introduced in a recent work dedicated to scalar fields. Here, we shift our attention to fermions and similarly to
