Exact gauge fields from anti-de Sitter space
Savan Hirpara, Kaushlendra Kumar, Olaf Lechtenfeld +1
In 1977 Lüscher found a class of SO(4)-symmetric SU(2) Yang-Mills solutions in Minkowski space, which have been rederived 40 years later by employing the isometry $S^3\cong\mathrm…

A hyperbolic Kac-Moody Calogero model
Olaf Lechtenfeld, Don Zagier
A new kind of quantum Calogero model is proposed, based on a hyperbolic Kac-Moody algebra. We formulate nonrelativistic quantum mechanics on the Minkowskian root space of the simpl…
