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…
OSp(4|2) Superconformal Mechanics
Sergey Fedoruk, Evgeny Ivanov, Olaf Lechtenfeld
A new superconformal mechanics with OSp(4|2) symmetry is obtained by gauging the U(1) isometry of a superfield model. It is the one-particle case of the new N=4 super Calogero mode…
Instantons and Yang-Mills Flows on Coset Spaces
Tatiana A. Ivanova, Olaf Lechtenfeld, Alexander D. Popov +1
We consider the Yang-Mills flow equations on a reductive coset space G/H and the Yang-Mills equations on the manifold R x G/H. On nonsymmetric coset spaces G/H one can introduce ge…
