  • Directly comparing GW150914 with numerical solutions of Einstein's equations for binary black hole coalescence 
    Abbott, B.P.; Allen, Bruce; Aufmuth, Peter; Bisht, A.; Danzmann, Karsten; Denker, T.; Heurs, M.; Kaufer, S.; Krueger, C.; Lough, J.D.; Lück, Harald; Sawadsky, A.; Schütte, D.; Steinmeyer, D.; Vahlbruch, H.; Willke, Benno; Wimmer, M.H.; Wittel, H.; et al.; LIGO Scientific Collaboration; Virgo Collaboration (College Park, MD : American Physical Society, 2016)
    We compare GW150914 directly to simulations of coalescing binary black holes in full general relativity, including several performed specifically to reproduce this event. Our calculations go beyond existing semianalytic ...
  • Extreme-ultraviolet frequency combs from high-order harmonic generation with few-cycle pulse trains 
    Tudorovskaya, Maria; Lein, Manfred (College Park, MD : American Physical Society, 2017)
    The spectrum of a high-repetition train of laser pulses consists of many equally spaced lines, forming an optical frequency comb which is useful for high-precision spectroscopy. By exposing atoms to a train of strong pulses, ...
  • 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 ...
  • 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 ...
  • Towards the fast scrambling conjecture 
    Lashkari, Nima; Stanford, Douglas; Hastings, Matthew; Osborne, Tobias J.; Hayden, Patrick (New York, NY : Springer International Publishing, 2013)
    Many proposed quantum mechanical models of black holes include highly non-local interactions. The time required for thermalization to occur in such models should reflect the relaxation times associated with classical black ...
