  • 4D supersymmetric gauge theories of spacetime translations 
    Brandt, Friedemann (Berlin, Heidelberg : Springer, 2022)
    The paper addresses the question whether in four spacetime dimensions, besides standard supergravity theories, field theories exist whose symmetries include local spacetime translations and supersymmetries generated by ...
  • Asymptotic symmetries of scalar electrodynamics and of the abelian Higgs model in Hamiltonian formulation 
    Tanzi, Roberto; Giulini, Domenico (Berlin ; Heidelberg : Springer, 2021)
    We investigate the asymptotic symmetry group of a scalar field minimally-coupled to an abelian gauge field using the Hamiltonian formulation. This extends previous work by Henneaux and Troessaert on the pure electromagnetic ...
  • Asymptotic symmetries of Yang-Mills fields in Hamiltonian formulation 
    Tanzi, Roberto; Giulini, Domenico (Berlin ; Heidelberg : Springer, 2020)
    We investigate the asymptotic symmetry group of the free SU(N )-Yang-Mills theory using the Hamiltonian formalism. We closely follow the strategy of Henneaux and Troessaert who successfully applied the Hamiltonian formalism ...
  • 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 ...
  • Minimal realization of ℓ-conformal Galilei algebra, Pais-Uhlenbeck oscillators and their deformation 
    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 ...
  • Nicolai maps with four-fermion interactions 
    Casarin, Lorenzo; Lechtenfeld, Olaf; Rupprecht, Maximilian (Berlin ; Heidelberg : Springer, 2023)
    Nicolai maps offer an alternative description of supersymmetric theories via nonlinear and nonlocal transformations characterized by the so-called ‘free-action’ and ‘determinant-matching’ conditions. The latter expresses ...
  • Regularized degenerate multi-solitons 
    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 ...
  • SU(2|1) supersymmetric mechanics on curved spaces 
    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 ...
