Superstring field theory

open access: yesNuclear Physics B, 1984
Abstract Superstring field theories are formulated in terms of light-cone-gauge superfields that are functionals of string coordinates x ( σ ) and ϑ ( σ ). The formalism used preserves only the manifest SU(4) symmetry that corresponds to rotations among six of the eight transverse directions.

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

open access: yesJournal 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.

Holographic Effective Field Theories [PDF]

open access: yes, 2016
We derive the four-dimensional low-energy effective field theory governing the moduli space of strongly coupled superconformal quiver gauge theories associated with D3-branes at Calabi-Yau conical singularities in the holographic regime of validity.

Detectors in weakly-coupled field theories

open access: yesJournal of High Energy Physics, 2023
We initiate a study of asymptotic detector operators in weakly-coupled field theories. These operators describe measurements that can be performed at future null infinity in a collider experiment.

Chameleon field theories [PDF]

open access: yesClassical and Quantum Gravity, 2013
Chameleons are light scalar fields with remarkable properties. Through the interplay of self-interactions and coupling to matter, chameleon particles have a mass that depends on the ambient matter density. The manifestation of the fifth force mediated by chameleons therefore depends sensitively on their environment, which makes for a rich phenomenology.

Inverse bootstrapping conformal field theories

open access: yesJournal of High Energy Physics, 2018
We propose a novel approach to study conformal field theories (CFTs) in general dimensions. In the conformal bootstrap program, one usually searches for consistent CFT data that satisfy crossing symmetry.

The impact of rule updates on the performance of racewalkers and the classification of countries: An analysis at the Olympic Games

open access: yesSport TK
Numerous controversies arose over the judgment of the racewalking events, and the rules were amended more than once. Before 1995, the rule required constant touch with the ground, and the need for a straight knee was only applied in the upright vertical

Bootstrapping massive quantum field theories

open access: yesJournal of High Energy Physics, 2020
We propose a new non-perturbative method for studying UV complete unitary quantum field theories (QFTs) with a mass gap in general number of spacetime dimensions.

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

open access: yesJournal 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 ...

Relativistic field theories in a magnetic background as noncommutative field theories

open access: yes, 2004
We study the connection of the dynamics in relativistic field theories in a strong magnetic field with the dynamics of noncommutative field theories (NCFT). As an example, the Nambu-Jona-Lasinio models in spatial dimensions $d \geq 2$ are considered.
