Finite volume form factors in integrable theories

Journal of High Energy Physics
We develop a new method to calculate finite size corrections for form factors in two-dimensional integrable quantum field theories. We extract these corrections from the excited state expectation value of bilocal operators in the limit when the operators

An inverse mass expansion for the mutual information in free scalar QFT at finite temperature

Journal of High Energy Physics, 2020
We study the entanglement entropy and the mutual information in coupled harmonic systems at finite temperature. Interestingly, we find that the mutual information does not vanish at infinite temperature, but it rather reaches a specific finite value ...

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.

Odd dimensional nonlocal Liouville conformal field theories

Journal of High Energy Physics, 2022
We construct Euclidean Liouville conformal field theories in odd number of dimensions. The theories are nonlocal and non-unitary with a log-correlated Liouville field, a Q $$ \mathcal{Q} $$ -curvature background, and an exponential Liouville-type ...
