  • Classical capillary turbulence on the surface of quantum liquid He-II 
    Abdurakhimov, L.V.; Brazhnikov, M.Yu.; Remizov, I.A.; Levchenko, A.A. (Физика низких температур, 2011)
    Superfluid helium-4 is a unique liquid for experimental study of capillary wave turbulence due to its very low viscosity. We have studied the influence of amplitude and spectral characteristics of the excitation force on ...
  • Extraction of charges from beneath the surface of liquid hydrogen 
    Levchenko, A.A.; Mezhov-Deglin, L.P. (Физика низких температур, 1996)
    Experimental results are presented which confirm the existence of electron bubbles in liquid hydrogen. The effective values of the barrier preventing the glectron to escape from the liquid into the gas and the electron ...
  • Nanotube-based source of charges for experiments with solid helium at low temperatures 
    Borisenko, D.N.; Walmsley, P.M.; Golov, A.I.; Kolesnikov, N.N.; Kotov, Yu.V.; Levchenko, A.A.; Mezhov-Deglin, L.P.; Fear, M.J. (Физика низких температур, 2015)
    Methods of preparation of the field-emission sources of charges from carbon nanotubes suitable for study of injected charges in solid helium at low temperatures T < 1 K are presented. The sources have been prepared by ...
  • Observation of dynamic maximum in a turbulent cascade on the surface of liquid hydrogen 
    Remizov, I.A.; Brazhnikov, M.Yu.; Levchenko, A.A. (Физика низких температур, 2016)
    We report on the experimental observation of energy accumulation near the high frequency boundary of the inertial range in the spectrum of turbulence in a system of capillary waves on the surface of liquid hydrogen driven ...
  • Reconstruction of the charged surface of liquid hydrogen 
    Kolmakov, G.V.; Levchenko, A.A.; Mezhov-Deglin, L.P.; Trusov, A.B. (Физика низких температур, 1998)
    The evolution of shape of the surface of equipotentially charged liquid hydrogen film condensed on the lower or upper plate of a horizontally placed diode in external electric fields has been studied experimentally under ...
  • Shielding characteristics of water 
    Levchenko, A.A.; Likhter, A.M.; Khramov, D.A.; Gryaznova, V.A.; Shikin, V.B. (Физика низких температур, 2015)
    In this article we demonstrate that a relatively small density of intrinsic ions in pure water has a significant impact on the development of the instability of the liquid–vapor boundary in an external electric field ...
  • Stationary nonlinear waves at the surface of a thin liquid layer under inverted gravitation conditions 
    Kolmakov, G.V.; Lebedeva, E.V.; Levchenko, A.A.; Mezhov-Deglin, L.P.; Trusov, A.B.; Shikin, V.B. (Физика низких температур, 2004)
    Instability of the flat surface of a thin liquid layer wetting a solid substrate under inverted gravitation conditions is discovered. The development of this instability leads to formation of a new stationary nonuniform ...
  • Turbulence of second sound waves in superfluid He II 
    Brazhnikov, M.Yu.; Efimov, V.B.; Kolmakov, G.V.; Levchenko, A.A.; Lebedeva, E.V.; Mezhov-Deglin, L.P. (Физика низких температур, 2004)
    We communicate the results of numerical studies of acoustic turbulence in a system of slightly dissipating, nonlinear second sound waves in superfluid He II. It is shown that at sufficiently high amplitude of the external ...
  • Wave turbulence on the surface of liquid hydrogen in restricted geometry: the influence of the boundary conditions 
    Brazhnikov, M.Yu.; Levchenko, A.A.; Mezhov-Deglin, L.P.; Remizov, I.A. (Физика низких температур, 2015)
    Formation of low frequency harmonics on turbulent distribution in the system of waves on the surface of liquid hydrogen has been studied in the frequency range 1–100 Hz (capillary-gravity waves). It is shown that the geometry ...
