D-branes in the WZW model
A. Yu. Alekseev, V. Schomerus
It is stated in the literature that D-branes in the WZW-model associated with the gluing condition J = - \bar{J} along the boundary correspond to branes filling out the whole group…
Vacua, Propagators, and Holographic Probes in AdS/CFT
Ulf H. Danielsson, Esko Keski-Vakkuri, Martin Kruczenski
In this paper we investigate the relation between the bulk and boundary in AdS/CFT. We first discuss the relation between the Poincare and the global vacua, and then study various…
Generalized Calogero models through reductions by discrete symmetries
Alexios P. Polychronakos
We construct generalizations of the Calogero-Sutherland-Moser system by appropriately reducing a classical Calogero model by a subset of its discrete symmetries. Such reductions re…
Bulk and Boundary Dynamics in BTZ Black Holes
Esko Keski-Vakkuri
Recently, the AdS/CFT conjecture of Maldacena has been investigated in Lorentzian signature by Balasubramanian et. al. We extend this investigation to Lorentzian BTZ black hole spa…
Partially Dual variables in SU(2) Yang-Mills Theory
Ludvig Faddeev, Antti J. Niemi
We propose a reformulation of SU(2) Yang-Mills theory in terms of new variables. These variables are appropriate for describing the theory in its infrared limit, and indicate that…
(Meta)stable closed vortices in 3+1 dimensional gauge theories with an extended Higgs sector
Antti J. Niemi, Kaupo Palo, Sami Virtanen
In gauge theories with an extended Higgs sector the classical equations of motion can have solutions that describe stable, closed finite energy vortices. Such vortices separate two…
Graviton scattering in an M-orientifold background
Ulf H. Danielsson, Par Stjernberg, Martin Kruczenski
In this paper we study the scattering of gravitons off a five orientifold in eleven dimensions. We compare the supergravity result with a two loop M(atrix) model calculation and fi…
Generalized Calogero-Sutherland systems from many-matrix models
Alexios P. Polychronakos
We construct generalizations of the Calogero-Sutherland-Moser system by appropriately reducing a model involving many unitary matrices. The resulting systems consist of particles o…
Quarks, monopoles and dyons at large N
Ulf H. Danielsson, Alexios P. Polychronakos
We study a system of external particles of various charges in N =4 super Yang-Mills in the large N limit at finite temperature. We demonstrate that at high enough temperature parti…
