Harmonic N=2 Mechanics
Anton Galajinsky, Olaf Lechtenfeld
N=2 superconformal many-body quantum mechanics in arbitrary dimensions is governed by a single scalar prepotential which determines the bosonic potential and the boson-fermion coup…
Supersymmetric Calogero models by gauging
Sergey Fedoruk, Evgeny Ivanov, Olaf Lechtenfeld
New superconformal extensions of d=1 Calogero-type systems are obtained by gauging the U(n) isometry of matrix superfield models. We consider the cases of N=1, N=2 and N=4 one-dime…
On the N=2 Supersymmetric Camassa-Holm and Hunter-Saxton Equations
Jonatan Lenells, Olaf Lechtenfeld
We consider N=2 supersymmetric extensions of the Camassa-Holm and Hunter-Saxton equations. We show that they admit geometric interpretations as Euler equations on the superconforma…
Yang-Mills Instantons and Dyons on Group Manifolds
Tatiana A. Ivanova, Olaf Lechtenfeld
We consider Euclidean SU(N) Yang-Mills theory on the space GxR, where G is a compact semisimple Lie group, and introduce first-order BPS-type equations which imply the full Yang-Mi…
N=4 mechanics, WDVV equations and roots
Anton Galajinsky, Olaf Lechtenfeld, Kirill Polovnikov
N=4 superconformal multi-particle quantum mechanics on the real line is governed by two prepotentials, U and F, which obey a system of partial differential equations linear in U an…
Quantum Aspects of the Noncommutative Sine-Gordon Model
Seckin Kurkcuoglu, Olaf Lechtenfeld
In this paper, we first use semi-classical methods to study quantum field theoretical aspects of the integrable noncommutative sine-Gordon model proposed in [hep-th/0406065]. In pa…
