  • Deformed N= 8 mechanics of (8, 8, 0) multiplets 
    Ivanov, Evgeny; Lechtenfeld, Olaf; Sidorov, Stepan (Heidelberg : Springer Verlag, 2018)
    We construct new models of “curved” SU(4|1) supersymmetric mechanics based on two versions of the off-shell multiplet (8, 8, 0) which are “mirror” to each other. The worldline realizations of the supergroup SU(4|1) are ...
  • Is the Nicolai map unique? 
    Lechtenfeld, Olaf; Rupprecht, Maximilian (Berlin, Heidelberg : Springer, 2022)
    The Nicolai map is a field transformation that relates supersymmetric theories at finite couplings g with the free theory at g = 0. It is obtained via an ordered exponential of the coupling flow operator integrated from 0 ...
  • Nahm equations in supersymmetric mechanics 
    Fedoruk, Sergey; Ivanov, Evgeny; Lechtenfeld, Olaf (Heidelberg : Springer Verlag, 2012)
    We elaborate on a novel model of N=4 supersymmetric mechanics with extra spin variables. A dynamical linear (1,4,3) multiplet is coupled to a "semi-dynamical" linear (3,4,1) multiplet representing spin degrees of freedom ...
  • New actions for modified gravity and supergravity 
    Ketov, Sergey V.; Terada, T. (Heidelberg : Springer Verlag, 2013)
    We extend the f (R) gravity action by including a generic dependence upon the Weyl tensor, and further generalize it to supergravity by using the super-curvature R and super-Weyl W chiral superfields in N = 1 chiral curved ...
  • New D( 2, 1; alpha) mechanics with spin variables 
    Fedoruk, Sergey; Ivanov, Evgeny; Lechtenfeld, Olaf (New York, NY : Springer International Publishing, 2010)
    We elaborate on a novel superconformal mechanics model possessing D(2, 1; alpha) symmetry and involving extra U(2) spin variables. It is the one-particle case of the N=4 superconformal matrix model recently proposed in ...
  • New N = 2 superspace Calogero models 
    Krivonos, Sergey; Lechtenfeld, Olaf; Sutulin, Anton (Berlin ; Heidelberg : Springer, 2020)
    Starting from the Hamiltonian formulation of N = 2 supersymmetric Calogero models associated with the classical An, Bn, Cn and Dn series and their hyperbolic/trigonometric cousins, we provide their superspace description. ...
  • Quantum SU(2|1) supersymmetric Calogero-Moser spinning systems 
    Fedoruk, Sergey; Ivanov, Evgeny; Lechtenfeld, Olaf; Sidorov, Stepan (Heidelberg : Springer Verlag, 2018)
    SU(2|1) supersymmetric multi-particle quantum mechanics with additional semi-dynamical spin degrees of freedom is considered. In particular, we provide an N= 4 supersymmetrization of the quantum U(2) spin Calogero-Moser ...
  • SU(2|2) supersymmetric mechanics 
    Ivanov, Evgeny; Lechtenfeld, Olaf; Sidorov, Stepan (Heidelberg : Springer Verlag, 2016)
    We introduce a new kind of non-relativistic N = 8 supersymmetric mechanics, associated with worldline realizations of the supergroup SU(2|2) treated as a deformation of flat N = 8, d=1 supersymmetry. Various worldline ...
