  • Heterotic G(2)-manifold compactifications with fluxes and fermionic condensates 
    Gemmer, Karl-Philip; Lechtenfeld, Olaf (New York, NY : Springer International Publishing, 2013)
    We consider flux compactifications of heterotic string theory in the presence of fermionic condensates on M-1,M-2 x X-7 with both factors carrying a Killing spinor. In other words, M-1,M-2 is either de Sitter, anti-de ...
  • 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 ...
  • On hvLif-like solutions in gauged Supergravity 
    Bueno, P.; Chemissany, W.; Shahbazi, C.S (New York : Springer, 2014)
    We perform a thorough investigation of Lifshitz-like metrics with hyperscaling violation (hvLif) in four-dimensional theories of gravity coupled to an arbitrary number of scalars and vector fields, obtaining new solutions, ...
