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…
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…
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…
Non-Compact Calabi-Yau Spaces and Other Non-Trivial Backgrounds for 4-D Superstrings
E. Kiritsis, C. Kounnas, D. Lust
A large class of new 4-D superstring vacua with non-trivial/singular geometries, spacetime supersymmetry and other background fields (axion, dilaton) are found. Killing symmetries…
The Dual Faces of String Theory
E. Kiritsis
Duality symmetries for strings moving in non-trivial spacetime backgrounds are analysed. It is shown that, for backgrounds generated from compact WZW and coset models, such duality…
