    Melchert, O.; Willms, S.; Morgner, U.; Babushkin, I.; Demircan, A. ([London] : Macmillan Publishers Limited, part of Springer Nature, 2021)
    The nonlinear interaction of copropagating optical solitons enables a large variety of intriguing bound-states of light. We here investigate the interaction dynamics of two initially superimposed fundamental solitons at ...

  • Curvature-induced resolution of anti-brane singularities 
    Junghans, Daniel; Schmidt, Daniel; Zagermann, Marco (New York : Springer, 2014)
    We study AdS(7) vacua of massive type IIA string theory compactified on a 3-sphere with H-3 flux and anti-D6-branes. In such backgrounds, the anti-brane backreaction is known to generate a singularity in the H-3 energy ...

    Kozyrev, N.; Krivonos, S.; Lechtenfeld, O.; Nersessian, A.; Sutulin, A. (Bristol : Institute of Physics Publishing, 2018)

    Campagna, Francesco; Stevenhagen, Peter (Heidelberg : Springer, 2023)
