Gas-liquid critical parameters of asymmetric models of ionic fluids
O. V. Patsahan, T. M. Patsahan
The effects of size and charge asymmetry on the gas-liquid critical parameters of a primitive model (PM) of ionic fluids are studied within the framework of the statistical field t…
Low-temperature properties of the Hubbard model on highly frustrated one-dimensional lattices
O. Derzhko, J. Richter, A. Honecker +2
We consider the repulsive Hubbard model on three highly frustrated one-dimensional lattices -- sawtooth chain and two kagomé chains -- with completely dispersionless (flat) lowest…
Liquid-gas phase behavior of polydisperse dipolar hard-sphere fluid: Extended thermodynamic perturbation theory for central force associating potential
Yu. V. Kalyuzhnyi, S. Hlushak, P. T. Cummings
The liquid-gas phase diagram for polydisperse dipolar hard-sphere fluid with polydispersity in the hard-sphere size and dipolar moment is calculated using extension of the recently…
Confinement interaction in nonlinear generalizations of the Wick-Cutkosky model
Jurij W. Darewych, Askold Duviryak
We consider nonlinear-mediating-field generalizations of the Wick-Cutkosky model. Using an iterative approach and eliminating the mediating field by means of the covariant Green fu…
Exact evidence for the spontaneous antiferromagnetic long-range order in the two-dimensional hybrid model of localized Ising spins and itinerant electrons
Jozef Strecka, Akinori Tanaka, Lucia Canova +1
The generalized decoration-iteration transformation is adopted to treat exactly a hybrid model of doubly decorated two-dimensional lattices, which have localized Ising spins at the…
Radiation reaction, renormalization and conservation laws in six-dimensional classical electrodynamics
Yurij Yaremko
A self-action problem for a point-like charged particle arbitrarily moving in flat space-time of six dimensions is considered. A consistent regularization procedure is proposed whi…
Radiation reaction in 2+1 electrodynamics
Yurij Yaremko
A self-action problem for a pointlike charged particle arbitrarily moving in flat spacetime of three dimensions is considered. Outgoing waves carry energy-momentum and angular mome…
Self force in 2+1 electrodynamics
Yurij Yaremko
The radiation reaction problem for an electric charge moving in flat space-time of three dimensions is discussed. The divergences stemming from the pointness of the particle are st…
Polymers in crowded environment under stretching force: globule-coil transitions
V. Blavatska, W. Janke
We study flexible polymer macromolecules in a crowded (porous) environment, modelling them as self-attracting self-avoiding walks (SASAW) on site-diluted percolative lattices in sp…
Total electronic Raman scattering in the charge-density-wave phase of the spinless Falicov-Kimball model
O. P. Matveev, A. M. Shvaika, J. K. Freericks
The total electronic Raman scattering spectrum, including the nonresonant, mixed and resonant components, is determined for the charge-density-wave (CDW) phase of the spinless Fali…
Interference in the radiation of two point-like charges
Yurij Yaremko
Energy-momentum and angular momentum carried by electromagnetic field of two point-like charged particles arbitrarily moving in flat spacetime are presented. Apart from usual contr…
Two-dimensional electron liquid state at LaAlO3-SrTiO3 interfaces
M. Breitschaft, V. Tinkl, N. Pavlenko +8
Using tunneling spectroscopy we have measured the spectral density of states of the mobile, two-dimensional electron system generated at the LaAlO3-SrTiO3 interface. As shown by th…
Concentration and mass dependence of transport coefficients and correlation functions in binary mixtures with high mass-asymmetry
W. Fenz, I. M. Mryglod, O. Prytula +1
Correlation functions and transport coefficients of self-diffusion and shear viscosity of a binary Lennard-Jones mixture with components differing only in their particle mass are s…
Nonlinear relaxation of 0-dimension-trapped microcavity polaritons
Ounsi El Daif, Gael Nardin, Taofiq K. Paraiso +6
We study the emission properties of confined polariton states in shallow zero-dimensional traps under non-resonant excitation. We evidence several relaxation regimes. For slightly…
Polymer chains in confined geometries: Massive field theory approach
D. Romeis, Z. Usatenko
The massive field theory approach in fixed space dimensions is applied to investigate a dilute solution of long-flexible polymer chains in a good solvent between two parallel…
Resilience of public transport networks against attacks
B. Berche, C. von Ferber, T. Holovatch +1
The behavior of complex networks under failure or attack depends strongly on the specific scenario. Of special interest are scale-free networks, which are usually seen as robust un…
A coupled order parameter system on a scale-free network
V. Palchykov, C. von Ferber, R. Folk +1
The system of two scalar order parameters on a complex scale-free network is analyzed in the spirit of Landau theory. To add a microscopic background to the phenomenological approa…
Ground-state degeneracy and low-temperature thermodynamics of correlated electrons on highly frustrated lattices
A. Honecker, O. Derzhko, J. Richter
Highly frustrated lattices yield a completely flat lowest single-electron band. Remarkably, exact many-body ground states can be constructed for the repulsive Hubbard model and the…
Low-temperature thermodynamics of one class of flat-band models
O Derzhko, J Richter, A Honecker
We consider the antiferromagnetic Heisenberg model and the repulsive Hubbard model for a class of frustrated lattices with a completely dispersionless (flat) lowest one-particle (e…
Mechanism of orbital reconstruction at the interfaces of transition metal oxides
Natalia Pavlenko
Orbital reconstruction at interfaces between YBa2Cu3O6 and SrO-terminated SrTiO3 is studied using local spin density approximation (LSDA) with intra-atomic Coulomb repulsion (LSDA+…
