A matrix model for WZW
Dorey, Nicholas; Tong, David; Turner, Carl (SpringerJournal of High Energy Physics, 2016-08-01)We study a U($\small N$) gauged matrix quantum mechanics which, in the large $\small N$ limit, is closely related to the chiral WZW conformal field theory. This manifests itself in two ways. First, we construct the left-moving ...

ADHM and the 4d quantum Hall effect
Barns-Graham, A; Dorey, Nicholas; Lohitsiri, N; Tong, David; Turner, Carl (Journal of High Energy Physics, 2018-04-01)© 2018, The Author(s). Yang-Mills instantons are solitonic particles in d = 4 + 1 dimensional gauge theories. We construct and analyse the quantum Hall states that arise when these particles are restricted to the lowest ...

Matrix model for non-Abelian quantum Hall states
Dorey, Nicholas; Tong, David; Turner, Carl (American Physical SocietyPhysical Review B, 2016-08-09)We propose a matrix quantum mechanics for a class of non-Abelian quantum Hall states. The model describes electrons which carry an internal SU($p$) spin. The ground states of the matrix model include spin-singlet generalizations ...

Spiky strings and the AdS/CFT correspondence
Losi, Manuel (University of CambridgeDepartment of Applied Mathematics and Theoretical Physics, 2011-10-11)In this dissertation, we explore some aspects of semiclassical type IIB string theory on AdS3 × S1 and on pure AdS3 in the limit of large angular momentum S. We first focus on the integrability technique known as ...
