Fractional exclusion statistics in disordered interacting particle systems
George Alexandru Nemnes, Dragos-Victor Anghel
We develop a model based on the fractional exclusion statistics (FES) applicable to non-homogeneous interacting particle systems. Here the species represent elementary volumes in a…
Scattering of phonons on two-level systems in disordered crystals
Dragoş-Victor Anghel, Dmitry Churochkin
We calculate the scattering rates of phonons on two-level systems in disordered trigonal and hexagonal crystals. We apply a model in which the two-level system, characterized by a…
The tensor of interaction of a two-level system with an arbitrary strain field
D. V. Anghel, T. Kühn, Y. M. Galperin +1
The interaction between two-level systems (TLS) and strain fields in a solid is contained in the diagonal matrix element of the interaction hamiltonian, , which, in general, has…
Interaction of two level systems in amorphous materials with arbitrary phonon fields
D. V. Anghel, T. Kühn, Y. M. Galperin +1
To describe the interaction of the two level systems (TLSs) of an amorphous solid with arbitrary strain fields, we introduce a generalization of the standard interaction Hamiltonia…
