  • Position-dependent spin-orbit coupling for ultracold atoms 
    Su, S.-W.; Gou, S.-C.; Liu, I.-K.; Spielman, I.B.; Santos, Luis; Acus, A.; Mekys, A.; Ruseckas, J.; Juzeliunas, G. (Bristol : IOP Publishing Ltd., 2015-03-31)
    We theoretically explore atomic Bose-Einstein condensates (BECs) subject to position-dependent spin-orbit coupling (SOC). This SOC can be produced by cyclically laser coupling four internal atomic ground (or metastable) ...
  • Probing Fano resonances with ultrashort pulses 
    Zhao, Jing; Lein, Manfred (Bristol : IOP Publishing Ltd., 2012)
    In this paper, autoionizing states in the one-dimensional helium atom are investigated by numerical solution of the time-dependent two-electron Schrodinger equation. The atom is irradiated by an extreme ultraviolet (XUV) ...
  • Sigma-model limit of Yang–Mills instantons in higher dimensions 
    Deser, Andreas; Lechtenfeld, Olaf; Popov, Alexander D. (Amsterdam : Elsevier Science BV, 2015)
    We consider the Hermitian Yang–Mills (instanton) equations for connections on vector bundles over a 2n-dimensional Kähler manifold Xwhich is a product Y×Zof p-and q-dimensional Riemannian manifold Yand Zwith p+q=2n. We ...
  • Uncertainty estimation of regionalised depth–duration–frequency curves in Germany 
    Shehu, Bora; Haberlandt, Uwe (Munich : EGU, 2023)
    The estimation of rainfall depth–duration–frequency (DDF) curves is necessary for the design of several water systems and protection works. These curves are typically estimated from observed locations, but due to different ...
  • Yang-Mills instantons and dyons on homogeneous G(2)-manifolds 
    Bauer, Irina; Ivanova, Tatiana A.; Lechtenfeld, Olaf; Lubbe, Felix (New York, NY : Springer International Publishing, 2010)
    We consider LieG-valued Yang-Mills fields on the space RxG/H, where G/H is a compact nearly Kahler six-dimensional homogeneous space, and the manifold RxG/H carries a G(2)-structure. After imposing a general G-invariance ...
