Features of Hopping Integral and Unconventional Orbital Modes for Quantum Skyrmions in Heisenberg Ferromagnet
R. A. Istomin, A. S. Moskvin
We use the coherent state approximation for the skyrmion in the isotropic quantum Heisenberg ferromagnet to obtain analytical expression for skyrmion hopping integral as a function…
Origin of Magnetoresistance Anomalies in Antiferromagnetic YBa_{2}Cu_{3}O_{6+x}
A. S. Moskvin, Yu. D. Panov
Specific d-wave angular dependence of the in-plane magnetoresistence in antiferromagnetic tetragonal YBa_{2}Cu_{3}O_{6+x} (x~0.3) on orientation of the external magnetic field in (…
Large non-adiabatic hole polarons and matrix element effects in the angle-resolved photoemission spectroscopy of dielectric cuprates
A. S. Moskvin, E. N. Kondrashov, V. I. Cherepanov
It has been made an extention of the conventional theory based on the assumption of the well isolated Zhang-Rice singlet to be a first electron-removal state in dielectric copper o…
Non-rigid shell model and novel correlational effects in atomic and molecular systems
Yu. D. Panov, A. S. Moskvin
Direct analytical and numerical calculation show that two-electron atomic configuration can be unstable with respect to a static or dynamic shift of the electron shells. This enabl…
