Canonical-dissipative limit cycle oscillators with a short-range interaction in phase space

Mongkolsakulvong, S.; Frank, T.D. (Condensed Matter Physics, 2010)

We consider limit cycle oscillators in terms of canonical-dissipative systems that exhibit a short-range interaction in velocity and position space as described by the Dirac delta function. We derive analytical expressions ...
Convenient formulae for some integrals in perturbation theory

Henderson, D. (Condensed Matter Physics, 2010)

The free energy and pressure of a fluid, as given by perturbation theory, involve integrals of the hard sphere correlation functions and their density derivatives. In most applications a straightforward procedure would be ...
Two-loop RG functions of the massive φ4 field theory in general dimensions

Shpot, M.A. (Condensed Matter Physics, 2010)

Two-loop Feynman integrals of the massive φ4d field theory are explicitly obtained for generic space dimensions d. Corresponding renormalization-group functions are expressed in a compact form in terms of Gauss hypergeometric ...
On the critical behaviour of two-dimensional liquid crystals

Fariñas-Sánchez, A.l.; Botet, R.; Berche, B.; Paredes, R. (Condensed Matter Physics, 2010)

The Lebwohl-Lasher (LL) model is the traditional model used to describe the nematic-isotropic transition of real liquid crystals. In this paper, we develop a numerical study of the temperature behaviour and of finite-size ...
Properties of a charge in the nanoheterosystems with quantum wells and barriers

Boichuk, V.I.; Bilynskyi, I.V.; Shakleina, I.O.; Holskyi, V.B. (Condensed Matter Physics, 2010)

In the paper a quasi-one-dimensional three-layer nanowire (NW) with an intermediate layer at the separation boundaries is described by the Kronig-Penney model with δ-function potentials. The distance between the last or ...
Characterization of 1-3 piezoelectric polymer composites -- a numerical and analytical evaluation procedure for thickness mode vibrations

Madhusudhana Rao, C.V.; Prasad, G. (Condensed Matter Physics, 2010)

Biomedical transducers widely employ piezoceramic polymer composites with 1-3 connectivity. The research is aimed at determining the effective material properties of these composites in the micrometer scale by simulation. ...
Polar interface optical phonon states and their dispersive properties of a wurtzite GaN quantum dot: quantum size effect

Zhang, L. (Condensed Matter Physics, 2010)

Based on the macroscopic dielectric continuum model, the interface-optical-propagating (IO-PR) mixing phonon modes of a quasi-zero-dimensional (Q0D) wurtzite cylindrical quantum dot (QD) structure are derived and studied. ...

Phase diagrams of the Bose-Fermi-Hubbard model: Hubbard operator approach

Stasyuk, I.V.; Mysakovych, T.S.; Krasnov, V.O. (Condensed Matter Physics, 2010)

The phase transitions in the Bose-Fermi-Hubbard model are investigated. The boson Green's function is calculated in the random phase approximation (RPA) and the formalism of the Hubbard operators is used. The regions of ...
Entropic solvation force between surfaces modified by grafted chains: a density functional approach

Pizio, S.; Sokołowski, O. (Condensed Matter Physics, 2010)

The behavior of a hard sphere fluid in slit-like pores with walls modified by grafted chain molecules composed of hard sphere segments is studied using density functional theory. The chains are grafted to opposite walls ...
Hole, impurity and exciton states in a spherical quantum dot

Boichuk, V.I.; Bilynskyi, I.V.; Leshko, R.Ya. (Condensed Matter Physics, 2010)

The 3x3 kp hole Hamiltonian for the wave-function envelopes (effective mass Hamiltonian) was used for calculation of discrete states of the hole and acceptor hydrogenic impurity in a spherical Si/SiO2 nanoheterostructure ...
Ferrimagnetism in the Hubbard, dimmer-connector frustrated chain

Rössler, J.; Mainemer, D. (Condensed Matter Physics, 2010)

We study the AB2 "dimmer-connector" chain within a generalized Hubbard model, which contains site-dependent parameters, and different chemical potentials for A and B sites. Considering one electron per atom, we carry out ...
Dynamics of the Rochelle salt NaKC4H4O6·4H2O crystal studied within the Mitsui model extended by piezoelectric interaction and transverse field

Levitskii, R.R.; Andrusyk, A.Ya.; Zachek, I.R. (Condensed Matter Physics, 2010)

We calculated dynamic dielectric permittivity of the Rochelle salt within the Mitsui model, extended by piezoelectric interaction and transverse field. Calculations were based on the parameters derived earlier within the ...
Thermodynamics, dielectric permittivity and phase diagrams of the Rb1-x(NH4)xH2PO4 type proton glasses

Sorokov, S.I.; Levitskii, R.R.; Vdovych, A.S. (Condensed Matter Physics, 2010)

The cluster pseudospin model of proton glasses, which takes into account the energy levels of protons around the PO4 group, the long-range interactions between the hydrogen bonds, and an internal random deformational field ...
