Instanton Operators in Five-Dimensional Gauge Theories
N. Lambert, C. Papageorgakis, M. Schmidt-Sommerfeld
We discuss instanton operators in five-dimensional gauge theories. These are defined as disorder operators which create a non-vanishing second Chern class on a four-sphere surround…
Deconstructing (2,0) Proposals
N. Lambert, C. Papageorgakis, M. Schmidt-Sommerfeld
We examine the relationships between three proposals for the six-dimensional (2,0) theory: the DLCQ of hep-th/9707079, hep-th/9712117, the deconstruction prescription of hep-th/011…
Universe Explosions
Ram Brustein, Maximilian Schmidt-Sommerfeld
A scenario for a quantum big crunch to big bang transition is proposed. We first clarify the similarities between this transition and the final stages of black hole evaporation. Th…
M5-Branes, D4-Branes and Quantum 5D super-Yang-Mills
Neil Lambert, Constantinos Papageorgakis, Maximilian Schmidt-Sommerfeld
We revisit the relation of the six-dimensional (2,0) M5-brane Conformal Field Theory compactified on a circle to 5D maximally supersymmetric Yang-Mills Gauge Theory. We show that i…
High energy scattering in gravity and supergravity
Steven B. Giddings, Maximilian Schmidt-Sommerfeld, Jeppe R. Andersen
We investigate features of perturbative gravity and supergravity by studying scattering in the ultraplanckian limit, and sharpen arguments that the dynamics is governed by long-dis…
One-loop and D-instanton corrections to the effective action of open string models
Maximilian Schmidt-Sommerfeld
One-loop corrections to the gauge coupling and the gauge kinetic function in certain classes of four-dimensional D-brane models are computed. It is described how to determine D-ins…
