Coherence, decoherence, and memory effects in the problems of quantum surface diffusion
V. V. Ignatyuk
We consider surface diffusion of a single particle, which performs site-to-site under-barrier hopping, fulfils intrasite motion between the ground and the first excited states with…
Analysis of the 3d massive renormalization group perturbative expansions: a delicate case
B. Delamotte, M. Dudka, Yu. Holovatch +1
The effectiveness of the perturbative renormalization group approach at fixed space dimension d in the theory of critical phenomena is analyzed. Three models are considered: the O(…
About the relevance of the fixed dimension perturbative approach to frustrated magnets in two and three dimensions
B. Delamotte, M. Dudka, Yu. Holovatch +1
We show that the critical behaviour of two- and three-dimensional frustrated magnets cannot reliably be described from the known five- and six-loops perturbative renormalization gr…
Nonequilibrium statistical operator method in the Renyi statistics
B. Markiv, R. Tokarchuk, P. Kostrobij +1
The generalization of the Zubarev nonequilibrium statistical operator method for the case of Renyi statistics is proposed when the relevant statistical operator (or distribution fu…
Biconical critical dynamics
R. Folk, Yu. Holovatch, G. Moser
A complete two loop renormalization group calculation of the multicritical dynamics at a tetracritical or bicritical point in anisotropic antiferromagnets in an external magnetic f…
The equation of state of the n-vector model: collective variables method
P. R. Kozak, M. P. Kozlovskii, Z. Usatenko
The critical behavior of the three-dimensional n-vector model in the presence of an external field is investigated. Mathematical description is performed with the collective variab…
On conjectured local generalizations of anisotropic scale invariance and their implications
S. Rutkevich, H. W. Diehl, M. A. Shpot
The theory of generalized local scale invariance of strongly anisotropic scale invariant systems proposed some time ago by Henkel [Nucl. Phys. B \textbf{641}, 405 (2002)] is examin…
Critical phenomena on scale-free networks: logarithmic corrections and scaling functions
V. Palchykov, C. von Ferber, R. Folk +2
In this paper, we address the logarithmic corrections to the leading power laws that govern thermodynamic quantities as a second-order phase transition point is approached. For pha…
Spin vortices and vacancies: interactions and pinning on a square lattice
Oleksandr Kapikranian, Yurij Holovatch
The study gives a decisive answer to the recently risen question about the type and origin of interaction between spin vortices and spin vacancies in 2D spin models. The approach i…
Hydrogen transport in superionic system Rb3H(SeO4)2: a revised cooperative migration mechanism
N. Pavlenko, A. Pietraszko, A. Pawlowski +3
We performed density functional studies of electronic properties and mechanisms of hydrogen transport in Rb3H(SeO4)2 crystal which represents technologically promising class M3H(XO…
