  • A new ripplon branch in He II 
    Tanatarov, I.V.; Adamenko, I.N.; Nemchenko, K.E.; Wyatt, A.F.G. (Физика низких температур, 2010)
    We analyse the dispersion relation of ripplons, on the surface of superfluid helium, using the dispersive hydrodynamics approach and find a new ripplon branch. We obtain analytical equation for the dispersion relation and ...
  • Creation of superfluid helium rotons by a solid’s phonons incident normal to the interface 
    Adamenko, I.N.; Nemchenko, K.E; Tanatarov, I.V. (Вопросы атомной науки и техники, 2007)
    We solve the one-dimensional problem of quasiparticles’ transfer through the interface between a solid and superfluid helium. Superfluid helium is treated as a continuous medium with correlations. When a solid’s phonon is ...
  • Normal transmission of phonons with anomalous dispersion through the interface of two continuous media 
    Adamenko, I.M.; Nemchenko, K.E.; Tanatarov, I.V. (Физика низких температур, 2006)
    In this work the problem is solved of normal transmission of quasiparticles through the interface of two continuous media, one of which is quantum fluid. The quantum fluid is described as a continuous medium with ...
  • Phonons, rotons and ripplons at interfaces 
    Tanatarov, I.V.; Adamenko, I.N.; Nemchenko, K.E.; Wyatt, A.F.G. (Вопросы атомной науки и техники, 2012)
    We use dispersive hydrodynamics to describe thermal excitations of superfluid helium 4. Dispersion relation of the bulk quasiparticles, phonons and rotons, acts as an input parameter of the theory. Wiener and Hopf method ...
