Dynamic probes of quantum spin chains with the Dzyaloshinskii-Moriya interaction
Oleg Derzhko, Taras Verkholyak, Taras Krokhmalskii +1
We consider the spin-1/2 anisotropic XY chain in a transverse (z) field with the Dzyaloshinskii-Moriya interaction directed along z-axis in spin space to examine the effect of the…
Dynamic structure factors of the spin-1/2 XX chain with Dzyaloshinskii-Moriya interaction
Oleg Derzhko, Taras Verkholyak
We consider the spin-1/2 isotropic XY chain in a (z) transverse magnetic field with the Dzyaloshinskii-Moriya interaction directed along the z-axis in spin space and examine the ef…
Star polymers in correlated disorder
V. Blavats'ka, C. von Ferber, Yu. Holovatch
We analyze the impact of a porous medium (structural disorder) on the scaling of the partition function of a star polymer immersed in a good solvent. We show that corresponding sca…
Three-Dimensional Ising-Like System in an External Field: Microscopic Calculation of the Free Energy in the Higher Non-Gaussian Approximation
I. V. Pylyuk
An analytic method for deriving the free energy of a three-dimensional Ising-like system near the critical point in a homogeneous external field is developed in the model app…
A massive Feynman integral and some reduction relations for Appell functions
M. A. Shpot
New explicit expressions are derived for the one-loop two-point Feynman integral with arbitrary external momentum and masses and in D dimensions. The results are gi…
Phase Transitions in the Pseudospin-Electron Model
Ihor Stasyuk
A review of the present state of investigations of the pseudospin-electron model (PEM), which is used in the theory of strongly correlated electron systems, is given. The model is…
Efficient algorithms for rigid body integration using optimized splitting methods and exact free rotational motion
Ramses van Zon, Igor P. Omelyan, Jeremy Schofield
Hamiltonian splitting methods are an established technique to derive stable and accurate integration schemes in molecular dynamics, in which additional accuracy can be gained using…
Optical and dc transport properties of a strongly correlated charge density wave system: exact solution in the ordered phase of the spinless Falicov-Kimball model with dynamical mean-field theory
O. P. Matveev, A. M. Shvaika, J. K. Freericks
We derive the dynamical mean-field theory equations for transport in an ordered charge-density-wave phase on a bipartite lattice. The formalism is applied to the spinless Falicov-K…
CO-activator model for reconstructing Pt(100) surfaces: local microstructures and chemical turbulence
Natalia Pavlenko
We present the results of the modelling of CO adsorption and catalytic CO oxidation on inhomogeneous Pt(100) surfaces which contain structurally different areas. These areas are fo…
Statistical field theory for a multicomponent fluid: The collective variables approach
Oksana Patsahan, Ihor Mryglod, Jean-Michel Caillol
Using the collective variables (CV) method the basic relations of statistical field theory of a multicomponent non-homogeneous fluids are reconsidered. The corresponding CV action…
Phase coexistance in polydisperse mixture of hard-sphere colloidal and flexible chain particles
Y. V. Kalyuzhnyi, P. T. Cummings
A theoretical scheme for the calculation of the full phase diagram (including cloud and shadow curves, binodals and distribution functions of the coexisting phases) for colloid-pol…
Model C critical dynamics of random anisotropy magnets
M. Dudka, R. Folk, Yu. Holovatch +1
We study the relaxational critical dynamics of the three-dimensional random anisotropy magnets with the non-conserved n-component order parameter coupled to a conserved scalar dens…
Crossover behavior in fluids with Coulomb interactions
O. V. Patsahan, J. -M. Caillol, I. M. Mryglod
According to extensive experimental findings, the Ginzburg temperature for ionic fluids differs substantially from that of nonionic fluids [Schröer W., Weigärtner H. 2004 {…
Low-temperature thermodynamics for a flat-band ferromagnet: Rigorous versus numerical results
Oleg Derzhko, Andreas Honecker, Johannes Richter
The repulsive Hubbard model on a sawtooth chain exhibits a lowest single-electron band which is completely dispersionless (flat) for a specific choice of the hopping parameters. We…
