Extended supersymmetric Calogero model
Sergey Krivonos, Olaf Lechtenfeld, Alexander Provorov +1
We present a surprising redefinition of matrix fermions which brings the supercharges of the -extended supersymmetric Calogero model introduced in [1] to the stan…
Dual infrared limits of 6d =(2,0) theory
Olaf Lechtenfeld, Alexander D. Popov
Compactifying type 6d supersymmetric CFT on a product manifold either over or over $\…
Deformed mechanics of multiplets
Evgeny Ivanov, Olaf Lechtenfeld, Stepan Sidorov
We construct new models of `curved' SU supersymmetric mechanics based on two versions of the off-shell multiplet which are `mirror' to each other. The worldli…
Skyrme and Faddeev models in the low-energy limit of 4d Yang-Mills-Higgs theories
Olaf Lechtenfeld, Alexander D. Popov
Firstly, we consider Yang-Mills theory on with an adjoint Higgs field spontaneously breaking a compact gauge group to a subgroup , so that the Higgs vacu…
Yang-Mills solutions on de Sitter space of any dimension
Olaf Lechtenfeld, Gönül Ünal
For gauge groups SO, SU and Sp, we construct equivariant Yang-Mills solutions on de Sitter space in , and spacetime di…
Skyrme-Faddeev model from 5d super-Yang-Mills
Olaf Lechtenfeld, Alexander D. Popov
We consider 5d Yang-Mills-Higgs theory with a compact ADE-type gauge group and one adjoint scalar field on , where …
