Emergent Time and the M5-Brane
C. M. Hull, N. Lambert
We consider the maximal super-Yang-Mills theory in 5 Euclidean dimensions with SO(5) R-symmetry and 16 supersymmetries. We argue that the strong coupling limit of this theory (with…
Tachyon Dynamics and the Effective Action Approximation
N. D. Lambert, I. Sachs
Recently effective actions have been extensively used to describe tachyon condensation in string theory. While the various effective actions which have appeared in the literature h…
On Higher Derivative Terms in Tachyon Effective Actions
N. D. Lambert, I. Sachs
We reconstruct the tachyon effective action for unstable D-branes in superstring theory by examining its behaviour near exactly marginal deformations, where the ambigous higher der…
Two Loop Renormalization of Massive (p,q) Supersymmetric Sigma Models
N. D. Lambert
We calculate the beta-functions of the general massive (p,q) supersymmetric sigma model to two loop order using (1,0) superfields. The conditions for finiteness are discussed in re…
Quantizing the (0,4) Supersymmetric ADHM Sigma Model
N. D. Lambert
We discuss the quantization of the ADHM sigma model. We show that the only quantum contributions to the effective theory come from the chiral anomalies and compute the first and se…
Topological Massive Sigma Models
N. D. Lambert
In this paper we construct topological sigma models which include a potential and are related to twisted massive supersymmetric sigma models. Contrary to a previous construction th…
