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 ...

Further evidence for lattice-induced scaling
Horowitz, GT; Santos, Jorge Eduardo; Tong, David (Journal of High Energy Physics, 2012-12-05)

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 ...

More Abelian dualities in 2 + 1 dimensions
Karch, A; Robinson, B; Tong, David (SpringerJournal of High Energy Physics, 2017-01-01)We expand on the recent derivation of 3d dualities using bosonization. We present in some detail a general class of Abelian duals.

Non-abelian 3$D$ bosonization and quantum Hall states
Radičević, Ð; Tong, David; Turner, Carl (SpringerJournal of High Energy Physics, 2016-12-01)Bosonization dualities relate two different Chern-Simons-matter theories, with bosonic matter on one side replaced by fermionic matter on the other. We first describe a more general class of non-Abelian bosonization ...

On superconformal anyons
Doroud, Nima; Tong, David; Turner, Carl (SpringerJournal of High Energy Physics, 2016-01-22)In d = 2+1 dimensions, there exist field theories which are non-relativistic and superconformal. These theories describe two species of anyons, whose spins differ by 1/2, interacting in a harmonic trap. We compute the ...

Particle-Vortex Duality from 3D Bosonization
Karch, Andreas; Tong, David (American Physical SocietyPhysical Review X, 2016-09-19)We show how particle-vortex duality in $d$ = 2 + 1 dimensions arises as part of an intricate web of relationships between different field theories. The starting point is “bosonization,” a conjectured duality that uses flux ...

The Quantum Hall Effect in Supersymmetric Chern-Simons Theories
Tong, David; Turner, Carl (APSPhysical Review B, 2015-12-15)We introduce a supersymmetric Chern-Simons theory whose low energy physics is that of the fractional quantum Hall effect. The supersymmetry allows us to solve the theory analytically. We quantise the vortices and, by ...

Vortices and Monopoles in a Harmonic Trap
Tong, David; Turner, Carl (SpringerJournal of High Energy Physics, 2015-12-15)The Ω-deformation is a harmonic trap, penning certain excitations near the origin in a manner consistent with supersymmetry. Here we explore the dynamics of BPS monopoles and vortices in such a trap. We pay particular ...
