Simple flexible polymers in a spherical cage

Marenz, M.; Zierenberg, J.; Arkın, H.; Janke, W. (Condensed Matter Physics, 2012)

We report the results of Monte Carlo simulations investigating the effect of a spherical confinement within a simple model for a flexible homopolymer. We use the parallel tempering method combined with multi-histogram ...
Marginal dimensions for multicritical phase transitions

Dudka, M.; Folk, R.; Holovatch, Yu.; Moser, G. (Condensed Matter Physics, 2012)

The field-theoretical model describing multicritical phenomena with two coupled order parameters with n || and n⊥ components and of O(n||) ⊕ O(n⊥) symmetry is considered. Conditions for realization of different types of ...

Ferrimagnetic spin-1/2 chain of alternating Ising and Heisenberg spins in arbitrarily oriented magnetic field

Strečka, J.; Hagiwara, M.; Han, Y.; Kida, T.; Honda, Z.; Ikeda, M. (Condensed Matter Physics, 2012)

The ferrimagnetic spin-1/2 chain composed of alternating Ising and Heisenberg spins in an arbitrarily oriented magnetic field is exactly solved using the spin-rotation transformation and the transfer-matrix method. It is ...
Some statistical aspects of the spinor field Fermi-Bose duality

Simulik, V.M.; Krivsky, I.Yu.; Lamer, I.L. (Condensed Matter Physics, 2012)

The structure of 29-dimensional extended real Clifford-Dirac algebra, which has been introduced in our paper Phys. Lett. A, 2011, 375, 2479, is considered in brief. Using this algebra, the property of Fermi-Bose duality ...
From Brownian motion to power of fluctuations

Berche, B.; Holovko, M.; Trokhymchuk, A.; Vlachy, V. (Condensed Matter Physics, 2012)
Magnetization process in the exactly solved spin-1/2 Ising-Heisenberg model on decorated Bethe lattices

Strečka, J.; Ekiz, C. (Condensed Matter Physics, 2012)

The spin-1/2 Ising-Heisenberg model on diamond-like decorated Bethe lattices is exactly solved in the presence of the longitudinal magnetic field by combining the decoration-iteration mapping transformation with the method ...
Lviv period for Smoluchowski: Science, teaching, and beyond

Rovenchak, A. (Condensed Matter Physics, 2012)

A major part of Marian Smoluchowski's achievements in science corresponds to the period of his work at the University of Lviv. Since this part is well described in the literature, in the paper the emphasis is made on some ...
Entropy production in open quantum systems: exactly solvable qubit models

Morozov, V.G.; Röpke, G. (Condensed Matter Physics, 2012)

We present analytical results for the time-dependent information entropy in exactly solvable two-state (qubit) models. The first model describes dephasing (decoherence) in a qubit coupled to a bath of harmonic oscillators. ...
On the effect of superfluid flows on the interaction of microwaves with He II

Khodusov, V.D.; Naumovets, A.S. (Condensed Matter Physics, 2012)

The paper proposes a possible mechanism of interaction of microwaves with superfluid helium that results in an experimentally observed narrow peak of microwave absorption on the frequencies by the order of the roton ...
Goldstone mode singularities in O(n) models

Kaupužs, J.; Melnik, R.V.N.; Rimšāns, J. (Condensed Matter Physics, 2012)

Monte Carlo (MC) analysis of the Goldstone mode singularities for the transverse and the longitudinal correlation functions, behaving as G⊥ (k) ≅ a k-λ⊥ and G|| (k) ≅ b k-λ|| in the ordered phase at k → 0, is performed in ...
Critical behaviour of a 3D Ising-like system in the ρ⁶ model approximation: Role of the correction for the potential averaging

Pylyuk, I.V.; Ulyak, M.V. (Condensed Matter Physics, 2012)

The critical behaviour of systems belonging to the three-dimensional Ising universality class is studied theoretically using the collective variables (CV) method. The partition function of a one-component spin system is ...
Hydrodynamic states of phonons in insulators

Sokolovsky, S.A. (Condensed Matter Physics, 2012)

The Chapman-Enskog method is generalized for accounting the effect of kinetic modes on hydrodynamic evolution. Hydrodynamic states of phonon system of insulators have been studied in a small drift velocity approximation. ...
Temperature and pH driven association in uranyl aqueous solutions

Druchok, M.; Holovk, M. (Condensed Matter Physics, 2012)

An association behavior of uranyl ions in aqueous solutions is explored. For this purpose a set of all-atom molecular dynamics simulations is performed. During the simulation, the fractions of uranyl ions involved in dimer ...
Exact solution of a variety of X-ray probes in the Falicov-Kimball model with dynamical mean-field theory

Shvaika, A.M.; Freericks, J.K. (Condensed Matter Physics, 2012)

We examine the core-level X-ray photoemission spectroscopy (XPS), X-ray absorption near-edge spectroscopy (XANES) and X-ray emission spectroscopy (XES) in the Falicov-Kimball model by using the exact solution from dynamical ...
Recent developments in classical density functional theory: Internal energy functional and diagrammatic structure of fundamental measure theory

Schmidt, M.; Burgis, M.; Dwandaru, W.S.B.; Leithall, G.; Hopkin, P. (Condensed Matter Physics, 2012)

An overview of several recent developments in density functional theory for classical inhomogeneous liquids is given. We show how Levy's constrained search method can be used to derive the variational principle that underlies ...
Towards frustration of freezing transition in a binary hard-disk mixture

Huerta, A.; Carrasco-Fadanelli, V.; Trokhymchuk, A. (Condensed Matter Physics, 2012)

The freezing mechanism, recently suggested for a monodisperse hard-disk fluid [Huerta et al, Phys. Rev. E, 2006, 74, 061106] is extended here to an equimolar binary hard-disk mixtures. We are showing that for diameter ...
Semiquantitative theory for high-field low-temperature properties of a distorted diamond spin chain

Derzhko, O.; Richter, J.; Krupnitska, O. (Condensed Matter Physics, 2012)

We consider the antiferromagnetic Heisenberg model on a distorted diamond chain and use the localized-magnon picture adapted to a distorted geometry to discuss some of its high-field low-temperature properties. More ...
Spin torque antiferromagnetic nanooscillator in the presence of magnetic noise

Gomonay, H.; Loktev, V. (Condensed Matter Physics, 2012)

Spin-torque effects in antiferromagnetic (AFM) materials are of great interest due to the possible applications as high-speed spintronic devices. In the present paper we analyze the statistical properties of the current-driven ...
