Orientifold and Integrability: Super-Yang-Mills on
Joao Caetano, Shota Komatsu, Paolo Soresina +1
We study planar super Yang-Mills theory (SYM) on the real projective space using integrability, holography and supersymmetric localization, and disc…
Matrix Theory from Holography
Shota Komatsu, Eunwoo Lee, Chintan Patel
We propose a setup that embeds Matrix Theory for M-theory into the AdS/CFT correspondence, allowing the former to be tested using the latter. The central claim is a triality among…
Time-Dependent Integrability from Gauge Theory, I
Shota Komatsu, Jun-ichi Sakamoto, Anders Wallberg +1
Solvable time-dependent systems provide important settings for studying non-equilibrium physics, where exact results are rare. They are also useful for benchmarking quantum simulat…
Crosscap Defects
Nadav Drukker, Shota Komatsu, Anders Wallberg
We introduce a novel class of defects, termed crosscap defects, in conformal field theory (CFT) in general dimensions. These arise from quotienting the spacetime by a automor…
Continuous Family of Conformal Field Theories and Exactly Marginal Operators
Shota Komatsu, Yuya Kusuki, Marco Meineri +1
Does a conformal manifold imply the existence of exactly marginal operators? We answer this question affirmatively under the assumption that there exists a conformal interface with…
Dressing and Screening in Anti-de Sitter
Ankur, Lorenzo Di Pietro, Victor Gorbenko +2
Motivated by a question of defining gauge-invariant observables in cosmology and by the close connection between perturbation theory in de Sitter (dS) and Anti-de Sitter (AdS), we…
F-theorem for Quantum Field Theories in Anti-de Sitter Space
Davide Bason, Christian Copetti, Lorenzo Di Pietro +2
We introduce a regularized free energy for massive quantum field theories (QFTs) on Anti-de Sitter space (AdS). We conjecture this quantity to be monoton…
Chiral Composite Linear Dilaton as String Dual to Two-Dimensional Yang-Mills
Shota Komatsu, Pronobesh Maity
Two-dimensional Yang-Mills theory (2d YM) is arguably the simplest confining gauge theory and its large expansion has a structure of the genus expansion in string theory. Nev…
Worldsheet for Generalized Veneziano Amplitudes
Shota Komatsu, Pronobesh Maity
We present a worldsheet action that reproduces a class of dual resonance amplitudes discussed in the literature, which generalize the Veneziano amplitude for open strings. Our prop…
String Duals of Two-Dimensional Yang-Mills and Symmetric Product Orbifolds
Shota Komatsu, Pronobesh Maity
We propose a bosonic string dual to large chiral Yang-Mills in two dimensions at finite 't Hooft coupling. The worldsheet theory is a - system deformed by a chiral Polchi…
Coulomb Branch and Integrability
Frank Coronado, Shota Komatsu, Konstantin Zarembo
We study one-point functions of non-BPS single-trace operators on the Coulomb branch of planar supersymmetric Yang-Mills theory. Holography relates them to overlaps…
Exact Three-Point Functions in Superconformal Field Theories: Integrability vs. Localization
Gwenaël Ferrando, Shota Komatsu, Gabriel Lefundes +1
We propose an integrability approach for planar three-point functions at finite coupling in superconformal field theories obtained as orbifolds of $\…
Strings from Feynman Diagrams
Rajesh Gopakumar, Rishabh Kaushik, Shota Komatsu +2
For correlators in Super Yang-Mills preserving half the supersymmetry, we manifestly recast the gauge theory Feynman diagram expansion as a sum over dual closed str…
Einstein gravity from a matrix integral -- Part II
Shota Komatsu, Adrien Martina, Joao Penedones +2
Using supersymmetric localization, we compute the partition function and some protected correlators of the polarized IKKT matrix model. Surprisingly, we find that the original IKKT…
Einstein gravity from a matrix integral -- Part I
Shota Komatsu, Adrien Martina, João Penedones +2
We construct backreacted geometries dual to the supersymmetric mass deformation of the IKKT matrix model. They are Euclidean type IIB supergravity solutions given in terms of an el…
S-Matrix Bootstrap and Non-Invertible Symmetries
Christian Copetti, Lucia Cordova, Shota Komatsu
We initiate the S-matrix bootstrap analysis of theories with non-invertible symmetries in (1+1) dimensions. Our previous work showed that crossing symmetry of S-matrices in such th…
2d QCD and Integrability, Part II: Generalized QCD
Federico Ambrosino, Shota Komatsu
We extend the study of integrable structures and analyticity of the spectrum in large QCD to a broad class of theories called the generalized QCD, which are given by the…
Vacuum Condensates on the Coulomb Branch
Vyacheslav Ivanovskiy, Shota Komatsu, Victor Mishnyakov +3
We study correlation functions on the Coulomb branch of planar super-Yang- Mills theory (SYM), and their relationship with integrability, the operator product exp…
Non-Invertible Symmetries, Anomalies and Scattering Amplitudes
Christian Copetti, Lucia Cordova, Shota Komatsu
We show that crossing symmetry of S-matrices is modified in certain theories with non-invertible symmetries or anomalies. Focusing on integrable flows to gapped phases in two dimen…
Gravity from quantum mechanics of finite matrices
Shota Komatsu, Adrien Martina, João Penedones +3
We revisit the Berenstein-Maldacena-Nastase (BMN) conjecture relating M-theory on a PP-wave background and Matrix Quantum Mechanics (MQM) of matrices. In particular, we…
Cosmological Correlators at Finite Coupling
Lorenzo Di Pietro, Victor Gorbenko, Shota Komatsu
We study finite-coupling effects of QFT on a rigid de Sitter (dS) background taking the vector model at large as a solvable example. Extending standard large techniq…
2d QCD and Integrability, Part I: 't Hooft model
Federico Ambrosino, Shota Komatsu
We study analytic properties and integrable structures of the meson spectrum in large QCD. We show that the integral equation that determines the masses of the mesons, of…
Taming Mass Gap with Anti-de-Sitter Space
Christian Copetti, Lorenzo Di Pietro, Ziming Ji +1
Anti-de-Sitter space acts as an infra-red cut off for asymptotically free theories, allowing interpolation between a weakly-coupled small-sized regime and a strongly-coupled flat-s…
Boundary reparametrizations and six-point functions on the AdS string
Simone Giombi, Shota Komatsu, Bendeguz Offertaler +1
We compute the tree-level connected six-point function of identical scalar fluctuations of the AdS string worldsheet dual to the half-BPS Wilson line in planar Sup…
