Frequency depending permittivity of the Coulomb system with Bose-Einstein condensate
V. B. Bobrov, S. A. Trigger
The second-order singularity is found in the low-frequency region of the permittivity of a homogeneous and isotropic system of charged particles consisting of electrons and boson n…
Universality of phonon-roton spectrum in liquids and superfluidity of He II
V. B. Bobrov, S. A. Trigger, D. I. Litinski
Based on numerous experimental data on inelastic neutron and X-ray scattering in liquids, we assert that the phonon-roton spectrum of elementary excitations, predicted by Landau fo…
Universality of rotons in liquids, generalized superfluidity criterion and helons in helium II
V. B. Bobrov, S. A. Trigger
An analysis of experimental data shows that, in addition to phonon--roton excitations in superfluid helium, there necessarily exist at least one branch of elementary excitations wh…
Elementary excitations and heat capacity singularity in superfluid helium
V. B. Bobrov, S. A. Trigger
We proceed from the premise that the spectrum of elementary excitations in the normal component in Landau's theory of superfluidity should depend on the superfluid helium temperatu…
Diffusion in a Time-dependent External Field
S. A. Trigger, G. J. F. van Heijst, O. F. Petrov +1
The problem of diffusion in a time-dependent (and generally inhomogeneous) external field is considered on the basis of a generalized master equation with two times, introduced in…
Anomalous Transport in Velocity Space, from Fokker-Planck to General Equation
S. A. Trigger
The problem of anomalous diffusion in momentum (velocity) space is considered based on the master equation and the appropriate probability transition function (PTF). The approach r…
