  • Infrared light interaction with impurity gels in superfluid helium 
    Izotov, A.N.; Efimov, V.B. (Физика низких температур, 2011)
    The quick cooling of impurity–helium mixture into superfluid helium formats a distinctive soft matter — impurity–helium gel, clusters of which conglutinate into nanoparticles. The sizes of the particles and its mutual ...
  • Mutual interactions between objects oscillating in isotopically pure superfluid ⁴He in the T → 0 limit 
    Garg, D.; Efimov, V.B.; Giltrow, M.; McClintock, P.V.E.; Skrbek, L. (Физика низких температур, 2012)
    We report the results of experiments to explore interactions between physically separated oscillating objects in isotopically pure superfluid ⁴He at T ∼ 10 mK. The investigations focused mainly on 32 kHz quartz tuning forks, ...
  • Nonlinear and shock waves in superfluid He II 
    Kolmakov, G.V.; Efimov, V.B.; Ganshin, A.N.; McClintock, P.V.E.; Lebedeva, E.V.; Mezhov-Deglin, L.P. (Физика низких температур, 2006)
    We review studies of the generation and propagation of nonlinear and shock sound waves in He II (the superfluid phase of ⁴He), both under the saturated vapor pressure (SVP) and at elevated pressures. The evolution in ...
  • Observation of acoustic turbulence in a system of nonlinear second sound waves in superfluid ⁴He 
    Ganshin, A.N.; Efimov, V.B.; Kolmakov, G.V.; McClintock, P.V.E.; Mezhov-Deglin, L.P. (Физика низких температур, 2008)
    We discuss the results of recent studies of acoustic turbulence in a system of nonlinear second sound waves in a high-quality resonator filled with superfluid ⁴He. It was found that, when the driving amplitude was ...
  • Propagation of short, nonlinear, second-sound pulses through He-II in one- and three-dimensional geometry 
    Efimov, V.B.; Kolmakov, G.V.; Kuliev, A.S.; Mezhov-Deglin, L.P. (Физика низких температур, 1998)
    The results or an experimental study ot the evolution ot the shape ot nonlinear second-sound pulses in superfluid He-II are reported The pulses propagate in the bulk (3D geometry) and along a cryoacoustic waveguide tilled ...
  • 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 ...
