A one-dimensional theory for Higgs branch operators

Journal of High Energy Physics, 2018
We use supersymmetric localization to calculate correlation functions of half-BPS local operators in 3d N = 4 $$ \mathcal{N}=4 $$ superconformal field theories whose Lagrangian descriptions consist of vectormultiplets coupled to hypermultiplets.

Duality and the Equivalence Principle of Quantum Mechanics [PDF]

, 2000
Following a suggestion by Vafa, we present a quantum-mechanical model for S-duality symmetries observed in the quantum theories of fields, strings and branes.

Quantum Gravity as Topological Quantum Field Theory [PDF]

, 1995
The physics of quantum gravity is discussed within the framework of topological quantum field theory. Some of the principles are illustrated with examples taken from theories in which space-time is three dimensional.Comment: 23 pages, amstex, JMP special

Toric geometry and the dual of ℐ-extremization

Journal of High Energy Physics, 2019
We consider d = 3, N = 2 $$ \mathcal{N}=2 $$ gauge theories arising on membranes sitting at the apex of an arbitrary toric Calabi-Yau 4-fold cone singularity that are then further compactified on a Riemann surface, Σ g , with a topological twist that ...

The semi-classical expansion and resurgence in gauge theories: new perturbative, instanton, bion, and renormalon effects [PDF]

, 2012
We study the dynamics of four dimensional gauge theories with adjoint fermions for all gauge groups, both in perturbation theory and non-perturbatively, by using circle compactification with periodic boundary conditions for the fermions.

Is Quantum Field Theory Necessarily “Quantum”?

Quantum Reports
The mathematical universe of the quantum topos, which is formulated on the basis of classical Boolean snapshots, delivers a neo-realist description of quantum mechanics that preserves realism.

Morse Theory in Field Theory

, 2012
We describe correlations functions of topological quantum mechanics (TQM) in terms of Morse theory. We review the basics of topological field theories and discuss geometric and algebraic interpretations of TQM.

Relating Field Theories via Stochastic Quantization [PDF]

, 2009
This note aims to subsume several apparently unrelated models under a common framework. Several examples of well-known quantum field theories are listed which are connected via stochastic quantization.

Localization and Diagonalization: A review of functional integral techniques for low-dimensional gauge theories and topological field theories

, 1995
We review localization techniques for functional integrals which have recently been used to perform calculations in and gain insight into the structure of certain topological field theories and low-dimensional gauge theories.

New observables in topological instantonic field theories

, 2011
Instantonic theories are quantum field theories where all correlators are determined by integrals over the finite-dimensional space (space of generalized instantons).
