Self-duality and F theory
Sergei V. Ketov
The (2,2) world-sheet supersymmetric string theory is discussed from the viewpoint of string/membrane unification. The effective field theory in the closed string target space is k…
Mixed (open/closed) N=(2,2) string theory as an integrable deformation of self-duality
Sergei V. Ketov
The exact effective field equations of motion, corresponding to the perturbative mixed theory of open and closed (2,2) world-sheet supersymmetric strings, are investigated. It is s…
Solitons, monopoles and duality: from sine-Gordon to Seiberg-Witten
Sergei V. Ketov
An elementary introduction into the Seiberg-Witten theory is given. Many efforts are made to get it as pedagogical as possible, within a reasonable size. The selection of the relev…
Path-Integral Quantization of the (2,2) String
Jan Bischoff, Olaf Lechtenfeld
A complete treatment of the (2,2) NSR string in flat (2+2) dimensional space-time is given, from the formal path integral over N=2 super Riemann surfaces to the computational recip…
Scalar Deformations of Schwarzschild Holes and Their Stability
Helge Dennhardt, Olaf Lechtenfeld
We construct two solutions of the minimally coupled Einstein-scalar field equations, representing regular deformations of Schwarzschild black holes by a self-interacting, static, s…
Low Temperature Properties of Quantum Antiferromagnetic Chains with Alternating Spins S=1 and 1/2
S. Brehmer, H. -J. Mikeska, S. Yamamoto
We study the low-temperature properties of S=1 and 1/2 alternating spin chains with antiferromagnetic nearest-neighbor exchange couplings using analytical techniques as well as a q…
