Aspects of supersymmetric field theories in four and six dimensions [PDF]

, 2011
PhDSupersymmetry is an important concept in modern high energy physics. It has found many applications in theoretical considerations of supersymmetric gauge theories as well as in phenomenological approaches to physics beyond the Standard Model.

Reflected entropy and Markov gap in Lifshitz theories

Journal of High Energy Physics, 2023
We study the reflected entropy in (1+1)-dimensional Lifshitz field theory whose groundstate is described by a quantum mechanical model. Starting from tripartite Lifshitz groundstates, both critical and gapped, we derive explicit formulas for the Rényi ...

T T ¯ $$ T\overline{T} $$ deformations and the width of fundamental particles

Journal of High Energy Physics, 2022
We provide a simple geometric meaning for deformations of so-called T T ¯ $$ T\overline{T} $$ type in relativistic and non-relativistic systems. Deformations by the cross products of energy and momentum currents in integrable quantum field theories are ...

T T ¯ $$ T\overline{T} $$ flow as characteristic flows

Journal of High Energy Physics, 2023
We show that method of characteristics provides a powerful new point of view on T T ¯ $$ T\overline{T} $$ -and related deformations. Previously, the method of characteristics has been applied to T T ¯ $$ T\overline{T} $$ -deformation mainly to solve ...

Quantum quench and thermalization to GGE in arbitrary dimensions and the odd-even effect

Journal of High Energy Physics, 2020
In many quantum quench experiments involving cold atom systems the post-quench phase can be described by a quantum field theory of free scalars or fermions, typically in a box or in an external potential.

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.

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.

Entanglement and confinement in coupled quantum systems

Journal of High Energy Physics, 2021
We study some general properties of coupled quantum systems. We consider simple interactions between two copies of identical Hamiltonians such as the SYK model, Pauli spin chains with random magnetic field and harmonic oscillators.

Metric approach to a T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ -like deformation in arbitrary dimensions

Journal of High Energy Physics, 2022
We consider a one-parameter family of composite fields — bi-linear in the components of the stress-energy tensor — which generalise the T T ¯ $$ \mathrm{T}\overline{\mathrm{T}} $$ operator to arbitrary space-time dimension d ≥ 2. We show that they induce
