Bootstrapping smooth conformal defects in Chern-Simons-matter theories

Barak Gabai

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 N holographic theories, these fundamental observables are dual to the open-string partition function in Ad ...

Quantum groups as global symmetries

Aleksandr Zhabin, Jiaxin Qiao, Barak Gabai, Victor Gorbenko

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 living at the ends of topological lines. We describe the general constraint ...

Thermal Bootstrap of Matrix Quantum Mechanics

Barak Gabai

We implement a bootstrap method that combines stationary state conditions, thermal inequalities, and semidefinite relaxations of matrix logarithm in the ungauged one-matrix quantum mechanics, at finite rank N as well as in the large N limit, and determine ...

Bootstrapping Smooth Conformal Defects in Chern-simons-matter Theories (Erratum)

Barak Gabai

During the production stage both the original and revised sentences were wrongly retained in the document above equation (4.20), leading to a duplication. The correct sentence is: The same Λ also governs the two-point function of the displacement operator ...
