Duality in non-commutative gauge theories as a non-perturbative Seiberg-Witten map
Elias Kiritsis, Corneliu Sochichiu
We study the equivalence/duality between various non-commutative gauge models at the classical and quantum level. The duality is realised by a linear Seiberg-Witten-like map. The i…
Supersymmetry and Duality in Field Theory and String Theory
E. Kiritsis
This is a set of lectures given at the 99' Cargese Summer School: Particle Physics : Ideas and Recent Developments. They contain a pedestrian exposition of recent theoretical progr…
Thermodynamics of D-brane Probes
E. Kiritsis, T. R. Taylor
We discuss the dynamics and thermodynamics of particle and D-brane probes moving in non-extremal black hole/brane backgrounds. When a probe falls from asymptotic infinity to the ho…
Instabilities in Strong Magnetic Fields in String Theory
Elias Kiritsis, Costas Kounnas
We construct groundstates of the string with non-zero mass gap and non-trivial chromo-magnetic fields as well as curvature. The exact spectrum as function of the chromo-magnetic fi…
String Gravity and Cosmology: Some new ideas
Elias Kiritsis, Costas Kounnas
String theory provides the only consistent framework so far that unifies all interactions including gravity. We discuss gravity and cosmology in string theory. Conventional notions…
Gravitational Phenomena from Superstrings in Curved Spacetime
E. Kiritsis, C. Kounnas
The four-dimensional superstring solutions define at low energy effective supergravity theories. A class of them extends successfully the validity of the standard model up to the s…
