  • 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 ...
  • Krivonos, Sergey; Lechtenfeld, Olaf; Sorin, Alexander (Heidelberg : Springer Verlag, 2016)
    We present the minimal realization of the ℓ-conformal Galilei group in 2+1 dimensions on a single complex field. The simplest Lagrangians yield the complex PaisUhlenbeck oscillator equations. We introduce a minimal deformation ...
  • Correa, Francisco; Fring, Andreas (Heidelberg : Springer Verlag, 2016)
    We report complex PT-symmetric multi-soliton solutions to the Korteweg de-Vries equation that asymptotically contain one-soliton solutions, with each of them possessing the same amount of finite real energy. We demonstrate ...
  • Kozyrev, Nikolay; Krivonos, Sergey; Lechtenfeld, Olaf; Sutulin, Anton (Heidelberg : Springer Verlag, 2018)
    We present SU(2|1) supersymmetric mechanics on n-dimensional Riemannian manifolds within the Hamiltonian approach. The structure functions including prepotentials entering the supercharges and the Hamiltonian obey extended ...
