Interaction of phonons at superfluid helium-solid interfaces
I. N. Adamenko, E. K. Nemchenko
A new method of obtaining the interaction Hamiltonian of phonons at superfluid helium-solid interface is proposed in the work. Equations of hydrodynamic variables are obtained in t…
Transmission and reflection of phonons and rotons at the superfluid helium-solid interface
I. N. Adamenko, K. E. Nemchenko, I. V. Tanatarov
We solve the problem of the transmission and reflection of phonons and rotons at the interface between superfluid helium and a solid, for all angles of incidence and in both direct…
Pressure of thermal excitations in superfluid helium
I. N. Adamenko, K. E. Nemchenko, I. V. Tanatarov +1
We find the pressure, due to the thermal excitations of superfluid helium, at the interface with a solid. The separate contributions of phonons, rotons and rotons are d…
Interactions of Phonons and Rotons with Interfaces in Superfluid Helium
I. V. Tanatarov, I. N. Adamenko, K. E. Nemchenko +1
We solve the problem of beams of phonons and rotons incident on, and interacting with, solid surfaces. Phonons and rotons are the quasiparticles of superfluid helium and have a uni…
A new ripplon branch in He II
I. V. Tanatarov, I. N. Adamenko, K. E. Nemchenko +1
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…
Formation of a mesa shaped phonon pulse in superfluid He
I. N. Adamenko, K. E. Nemchenko, V. A. Slipko
We present a theory for the formation of a mesa shaped phonon pulse in superfluid He. Starting from the hydrodynamic equations of superfluid helium, we obtain the system of equ…
