  • 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 (New York, NY : Springer International Publishing, 2011)
    We overcome the barrier of constructing N - 4 superconformal models in one space dimension for more than three particles. The D(2, 1; alpha) superalgebra of our systems is realized on the coordinates and momenta of the ...
  • Louis, Jan; Triendl, Hagen; Zagermann, Marco (New York : Springer, 2015-10-13)
    We classify the N = 4 supersymmetric AdS(5) backgrounds that arise as solutions of five-dimensional N = 4 gauged supergravity. We express our results in terms of the allowed embedding tensor components and identify the ...
  • 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 ...
  • Correa, Francisco; Lechtenfeld, Olaf; Plyushchay, Mikhail (New York : Springer, 2014)
    It is long known that the rational Calogero model describing n identical particles on a line with inverse-square mutual interaction potential is quantum superintegrable. We review the (nonlinear) algebra of the conserved ...
  • 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 ...
  • Galajinsky, Anton; Lechtenfeld, Olaf (Berlin : Springer, 2019)
    As is known, any realization of SU(2) in the phase space of a dynamical sys- tem can be generalized to accommodate the exceptional supergroup D (2 ; 1;α ), which is the most general N = 4 supersymmetric ...
  • 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 ...
  • 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 ...
  • Galajinsky, Anton; Lechtenfeld, Olaf (Heidelberg : Springer Verlag, 2016)
    Recent years have seen an upsurge of interest in dynamical realizations of the superconformal group SU(1, 1|2) in mechanics. Remarking that SU(1, 1|2) is a particular member of a chain of supergroups SU(1, 1|n) parametrized ...
  • Danckaert, Thomas; Louis, Jan; Martinez-Pedrera, Danny; Spanjaard, Bastiaan; Triendl, Hagen (New York, NY : Springer International Publishing, 2011)
    We study compactifications of type IIA supergravity on six-dimensional manifolds with SU(2) structure and compute the low-energy effective action in terms of the non-trivial intrinsic torsion. The consistency with gauged ...
  • Georgiou, George; Gili, Valeria; Großardt, André; Plefka, Jan (Heidelberg : Springer Verlag, 2012)
    We report on a systematic perturbative study of three-point functions in planar SU(N) N = 4 super Yang-Mills theory at the one-loop level involving scalar field operators up to length five. For this we have computed a ...
