  • Long-Time Asymptotics for the Toda Shock Problem: Non-Overlapping Spectra 
    Egorova, I.; Michor, J.; Teschl, G. (Журнал математической физики, анализа, геометрии, 2018)
    We derive the long-time asymptotics for the Toda shock problem using the nonlinear steepest descent analysis for oscillatory Riemann-Hilbert factorization problems. We show that the half-plane of space/time variables splits ...

  • Long-wave light sensitivity of a thin film system based on PbI₂ and Cu 
    Sopinskyy, M.V.; Mynko, V.I.; Olkhovik, G.P. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2015)
    Photostimulated interaction in a sandwich-like thin film system based on PbI₂ and Cu (photodoping effect) makes it possible to use the system as a recording medium. On the other hand, since the layer consisting of copper ...
  • Long-wave spin excitations of crystalline s − d models

    Long-wave spin excitations in the perfect s-d model are studied. The Hamiltonian of the model includes, apart from usually treated spin-electron processes, the Heisenberg exchange interaction of atomic spins and the ...
  • Looking Back the Most Beautiful Molecule C60 after Quarter Century of Discovery Insert 
    Ōsawa, Eiji (Вісник НАН України, 2012)
    On the occasion of silver anniversary of the C60 discovery, the present situation of C60 research is briefly analyzed from three distinct angles: molecule, solid and nanoparticle. With regard to molecular angle, the long ...
  • Loop Quantum Gravity Phenomenology: Linking Loops to Observational Physics 
    Girelli, F.; Hinterleitner, F.; Major, S.A. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    Research during the last decade demonstrates that effects originating on the Planck scale are currently being tested in multiple observational contexts. In this review we discuss quantum gravity phenomenological models and ...
  • Loop Quantum Gravity Vacuum with Nondegenerate Geometry 
    Koslowski, T.; Sahlmann, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2012)
    In loop quantum gravity, states of the gravitational field turn out to be excitations over a vacuum state that is sharply peaked on a degenerate spatial geometry. While this vacuum is singled out as fundamental due to its ...
  • Loops in SU(2), Riemann Surfaces, and Factorization, I 
    Basor, E.; Pickrell, D. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    In previous work we showed that a loop g:S¹→SU(2) has a triangular factorization if and only if the loop g has a root subgroup factorization. In this paper we present generalizations in which the unit disk and its double, ...
  • Loosing thermodynamic stability in amorphous materials 
    Kokshenev, V.B. (Физика низких температур, 2011)
    The primary relaxation dynamics near the glass transformation temperature T g exhibits universal features in all glass formers, when showing two-level tunneling states (Low Temp. Phys. 35, 282 (2009)). Researchers have ...
