A stochastic epidemiological model and a deterministic limit for BitTorrent-like peer-to-peer file-sharing networks
George Kesidis, Takis Konstantopoulos, Perla Sousi
In this paper, we propose a stochastic model for a file-sharing peer-to-peer network which resembles the popular BitTorrent system: large files are split into chunks and a peer can…
Ultrafast pump-probe dynamics in ZnSe-based semiconductor quantum-wells
Henni Ouerdane, George Papageorgiou, Ian Galbraith +2
Pump-probe experiments are used as a controllable way to investigate the properties of photoexcited semiconductors, in particular, the absorption saturation. We present an experime…
SU(3)-Equivariant Quiver Gauge Theories and Nonabelian Vortices
Olaf Lechtenfeld, Alexander D. Popov, Richard J. Szabo
We consider SU(3)-equivariant dimensional reduction of Yang-Mills theory on Kaehler manifolds of the form M x SU(3)/H, with H = SU(2) x U(1) or H = U(1) x U(1). The induced rank tw…
Generalised Chern-Simons actions for 3d gravity and kappa-Poincare symmetry
Catherine Meusburger, Bernd Schroers
We consider Chern-Simons theories for the Poincare, de Sitter and anti-de Sitter groups in three dimensions which generalise the Chern-Simons formulation of 3d gravity. We determin…
Instantons and Donaldson-Thomas Invariants
Michele Cirafici, Annamaria Sinkovics, Richard J. Szabo
We review some recent progress in understanding the relation between a six dimensional topological Yang-Mills theory and the enumerative geometry of Calabi-Yau threefolds. The gaug…
Magnetic Charge Lattices, Moduli Spaces and Fusion Rules
L. Kampmeijer, J. K. Slingerland, B. J. Schroers +1
We analyze the set of magnetic charges carried by smooth BPS monopoles in Yang-Mills-Higgs theory with arbitrary gauge group G spontaneously broken to a subgroup H. The charges are…
