Report

Modeling evolution of composition patterns in a binary surface alloy

Publikováno v: Modelling and Simulation in Materials Science and Engineering 29, 015002 (2020)

Evolution of composition patterns in the annealed, single-crystal surface alloy film is considered in the presence of the spinodal decomposition, the compositional stress and the diffusion anisotropy. While the former two effects contribute to overal

Is the K-matrix approach adequate for describing overlapping resonances?

Autor: Henner, Victor, Belozerova, Tatyana

The K-matrix method is widely used unitary parametrization for several resonances with the same quantum numbers. But in fact resonances in this approach are separated and do not overlap.

Report

Preserving unitarity for overlapping multichannel states: Breit-Wigner versus K matrix -- comparison, advantages and disadvantages

Autor: Henner, Victor, Belozerova, Tatyana

The K-matrix method is often used to describe overlapping resonances. It guarantees the unitarity of the scattering matrix but its parameters are not resonances masses and widths. It is also unclear how to separate resonant and background contributio

Report

Morphologies, metastability and coarsening of quantum nanoislands on the surfaces of the annealed Ag(110) and Pb(111) thin films

Autor: Price, Donald L., Henner, Victor, Khenner, Mikhail

Publikováno v: Journal of Applied Physics 124, 174302 (2018)

Morphological evolution of heteroepitaxial nanoislands toward equilibrium (coarsening) is computed using the detailed continuum model that incorporates the quantum size effect. Results reveal the metastability of the "magic" heights, show the morphol

Report

The quantum mechanics correspondence principle for spin systems and its application for some magnetic resonance problems

Autor: Henner, Victor, Klots, Andrey, Belozerova, Tatyana

Problems of interacting quantum magnetic moments become exponentially complex with increasing number of particles. As a result, classical equations are often used but the validity of reduction of a quantum problem to a classical problem should be jus
