Manifestly SL(2, R) Duality-Symmetric Forms in ModMax Theory

Journal of High Energy Physics, 2022
In this paper, we will investigate a manifestly SL(2, R)-invariant structure for the energy-momentum tensor of ModMax theory as a nonlinear modification of Maxwell electrodynamics which includes conformal invariance as well. In the context of this theory,

Some Lower Dimensional Quantum Field Theories Reduced from Chern-Simons Gauge Theories

We study symmetry reductions in the context of Euclidean Chern-Simons gauge theories to obtain lower dimensional field theories. Symmetry reduction in certain gauge theories is a common tool for obtaining explicit soliton solutions.

Supersymmetric gauged scale covariance in ten and lower dimensions

, 2004
We present globally supersymmetric models of gauged scale covariance in ten, six, and four dimensions. This is an application of a recent similar gauging in three dimensions for a massive self-dual vector multiplet.

Comments on QCD3 and anomalies with fundamental and adjoint matter

Journal of High Energy Physics, 2022
’t Hooft anomaly matching is powerful for constraining the low energy phases of gauge theories. In 3d one common anomaly is the parity anomaly in a T-symmetric theory where one cannot gauge the global symmetry group without breaking the time-reversal ...

Light scalars on cosmological backgrounds

Journal of High Energy Physics, 2018
We study the behaviour of a light quartically self-interacting scalar field ϕ on curved backgrounds that may be described with the cosmological equation state parameter w.

(Non)-Invertible Topology in Quantum Field Theory [PDF]

, 2023
This thesis aims to highlight aspects of mathematics and physics that arise in topological field theories. We will consider invertible and noninvertible topological theories.

The 1-loop effective potential for the Standard Model in curved spacetime

Journal of High Energy Physics, 2018
The renormalisation group improved Standard Model effective potential in an arbitrary curved spacetime is computed to one loop order in perturbation theory.

Modular Hamiltonian of the scalar in the semi infinite line: dimensional reduction for spherically symmetric regions

Journal of High Energy Physics, 2023
We focus our attention on the one dimensional scalar theories that result from dimensionally reducing the free scalar field theory in arbitrary d dimensions.

On the Inherent Incompleteness of Scientific Theories [PDF]

, 2004
We examine the question of whether scientific theories can ever be complete. For two closely related reasons, we will argue that they cannot. The first reason is the inability to determine what are “valid empirical observations”, a result that is based ...

Nonperturbative bounds on scattering of massive scalar particles in d ≥ 2

Journal of High Energy Physics, 2022
We study two-to-two scattering amplitudes of a scalar particle of mass m. For simplicity, we assume the presence of ℤ2 symmetry and that the particle is ℤ2 odd.
