Worldsheet Instantons and the amplitude for string pair production in an external field as a WKB exact functional integral
James Gordon, Gordon W. Semenoff
We revisit the problem of charged string pair creation in a constant external electric field. The string states are massive and creation of pairs from the vacuum is a tunnelling pr…
Antisymmetric Wilson loops in SYM beyond the planar limit
James Gordon
We study the -BPS circular Wilson loop in the totally antisymmetric representation of the gauge group in supersymmetric Yang-Mills. This observable is…
Schwinger pair production: Explicit Localization of the world-line instanton
James Gordon, Gordon W. Semenoff
We present a simple proof that the imaginary part of the world-line path integral which computes the rate of Schwinger pair production of charged particles in a constant electric f…
N=2* Super-Yang-Mills Theory at Strong Coupling
Xinyi Chen-Lin, James Gordon, Konstantin Zarembo
The planar N=2* Super-Yang-Mills (SYM) theory is solved at large 't Hooft coupling using localization on S(4). The solution permits detailed investigation of the resonance phenomen…
World-line instantons and the Schwinger effect as a WKB exact path integral
James Gordon, Gordon W. Semenoff
A detailed study of the semiclassical expansion of the world line path integral for a charged relativistic particle in a constant external electric field is presented. We show that…
