Yang-Mills Flux Tube in AdS II: Effective String Theory

Barak Gabai, Victor Gorbenko, Bendeguz Offertaler

We continue the study of flux tubes in confining gauge theories placed in a rigid AdS background, focusing on the three-dimensional case. Our analysis is performed in the large-rad…

On the Flux Sectors of Matrix String Theory

Minjae Cho, Barak Gabai, Jaroslav Scheinpflug +1

We analyze the gapped flux vacua of 2D (8,8) SU(N) super-Yang-Mills theory. Based on the matrix string theory duality, we conjecture the spectrum of massive resonances in the gauge…

Bootstrapping Euclidean Two-point Correlators

Minjae Cho, Barak Gabai, Henry W. Lin +2

We develop a bootstrap approach to Euclidean two-point correlators, in the thermal or ground state of quantum mechanical systems. We formulate the problem of bounding the two-point…

Yang-Mills Flux Tube in AdS

Barak Gabai, Victor Gorbenko, Jiaxin Qiao

We initiate the study of flux tubes in confining gauge theories placed in a rigid AdS background, which serves as an infrared regulator. Varying the AdS radius from large to small…

Universal Constraints for Conformal Line Defects

Barak Gabai, Amit Sever, De-liang Zhong

We present a novel framework for deriving integral constraints for correlators on conformal line defects. These constraints emerge from the non-linearly realized ambient-space conf…

Quantum Groups as Global Symmetries II. Coulomb Gas Construction

Barak Gabai, Victor Gorbenko, Jiaxin Qiao +2

We study a conformal field theory that arises in the infinite-volume limit of a spin chain with global symmetry. Most operators in the theory are defect-ending operator…

Quantum Groups as Global Symmetries

Barak Gabai, Victor Gorbenko, Jiaxin Qiao +2

We study quantum field theories which have quantum groups as global internal symmetries. We show that in such theories operators are generically non-local, and should be thought as…

Thermal Bootstrap of Matrix Quantum Mechanics

Minjae Cho, Barak Gabai, Joshua Sandor +1

We implement a bootstrap method that combines stationary state conditions, thermal inequalities, and semidefinite relaxations of matrix logarithm in the ungauged one-matrix quantum…

Bootstrapping Smooth Conformal Defects in Chern-Simons-Matter Theories

Barak Gabai, Amit Sever, De-liang Zhong

The expectation value of a smooth conformal line defect in a CFT is a conformal invariant functional of its path in space-time. For example, in large holographic theories, thes…

Line operators in Chern-Simons-Matter theories and Bosonization in Three Dimensions II -Perturbative Analysis and All-loop Resummation

Barak Gabai, Amit Sever, De-liang Zhong

We study mesonic line operators in Chern-Simons theories with bosonic or fermionic matter in the fundamental representation. In this paper, we elaborate on the classification and p…

Bootstrapping the Ising Model on the Lattice

Minjae Cho, Barak Gabai, Ying-Hsuan Lin +3

We study the statistical Ising model of spins on the infinite lattice using a bootstrap method that combines spin-flip identities with positivity conditions, including reflection p…

Anyon Scattering from Lightcone Hamiltonian: the Singlet Channel

Barak Gabai, Joshua Sandor, Xi Yin

We study Chern-Simons theory coupled to massive fundamental fermions in the lightcone Hamiltonian formalism. Focusing on the planar limit, we introduce a consistent regulari…

Line Operators in Chern-Simons-Matter Theories and Bosonization in Three Dimensions

Barak Gabai, Amit Sever, De-liang Zhong

We study Chern-Simons theories at large with either bosonic or fermionic matter in the fundamental representation. The most fundamental operators in these theories are mesonic…

Exact quantization and analytic continuation

Barak Gabai, Xi Yin

In this paper we give a streamlined derivation of the exact quantization condition (EQC) on the quantum periods of the Schrödinger problem in one dimension with a general polynomia…

On The S-Matrix of Ising Field Theory in Two Dimensions

Barak Gabai, Xi Yin

We explore the analytic structure of the non-perturbative S-matrix in arguably the simplest family of massive non-integrable quantum field theories: the Ising field theory (IFT) in…

No Particle Production in Two Dimensions: Recursion Relations and Multi-Regge Limit

Barak Gabai, Dalimil Mazac, Andrei Shieber +2

We introduce high-energy limits which allow us to derive recursion relations fixing the various couplings of Lagrangians of two-dimensional relativistic quantum field theories with…

Large Gauge Symmetries and Asymptotic States in QED

Barak Gabai, Amit Sever

Large Gauge Transformations (LGT) are gauge transformations that do not vanish at infinity. Instead, they asymptotically approach arbitrary functions on the conformal sphere at inf…
