Resonant inelastic X-ray scattering in a Mott insulator
Nandan Pakhira, J. K. Freericks, A. M. Shvaika
We calculate the resonant inelastic X-ray scattering (RIXS) response in a Mott insulator which is described by the Falicov-Kimball model. The model can be solved exactly within the…
Analysis of inter-quark interactions in classical chromodynamics
Jurij W. Darewych, Askold Duviryak
The QCD gluon equation of motion is solved approximately by means of the Green function. This solution is used to reformulate the Lagrangian of QCD such that the gluon propagator a…
On the problem of a consistent description of kinetic and hydrodynamic processes in dense gases and liquids: Collective excitations spectrum
B. B. Markiv, I. P. Omelyan, M. V. Tokarchuk
Based on the generalized non-Markovian equations obtained earlier for a nonequilibrium one-particle distribution function and potential part of the averaged enthalpy density [Marki…
Coupling of a high-energy excitation to superconducting quasiparticles in a cuprate from Coherent Charge Fluctuation Spectroscopy
B. Mansart, J. Lorenzana, A. Mann +4
Dynamical information on spin degrees of freedom of proteins or solids can be obtained by Nuclear Magnetic Resonance (NMR) and Electron Spin Resonance (ESR). A technique with simil…
Spin-spin correlation function of the 2D XY model with weak site or bond dilution
Oleksandr Kapikranian
The spin-spin correlation function of the 2D XY model decays as a power law at all temperatures below the Berezinskii-Kosterlitz-Thouless transition point with a temperature depend…
Editorial process in scientific journals: analysis and modeling
O. Mryglod, Yu. Holovatch, I. Mryglod
The editorial handling of papers in scientific journals as a human activity process is considered. Using recently proposed approaches of human dynamics theory we examine the probab…
Localized states on triangular traps and low-temperature properties of the antiferromagnetic Heisenberg and repulsive Hubbard models
Mykola Maksymenko, Oleg Derzhko, Johannes Richter
We consider the antiferromagnetic Heisenberg and the repulsive Hubbard model on two -site one-dimensional lattices, which support dispersionless one-particle states correspondin…
Mitsui model with diagonal strains: A unified description of external pressure effect and thermal expansion of Rochelle salt NaKC_4H_4O_6\cdot4H_2O
A. P. Moina, R. R. Levitskii, I. R. Zachek
We elaborate a modification of the deformable two-sublattice Mitsui model of [Levitskii R.R. et al., Phys. Rev. B. 2003, 67, 174112] and [Levitskii R.R. et al., Condens. Matter Phy…
Phase transitions in the Mitsui model
Yu. I. Dublenych
In this paper, phase transitions in the Mitsui model without longitudinal field but with a transverse one are investigated in the mean field approximation. The one-to-one correspon…
Spectral densities and diagrams of states of one-dimensional ionic Pauli conductor
I. V. Stasyuk, O. Vorobyov, R. Ya. Stetsiv
We focus on the features of spectra and diagrams of states obtained via exact diagonalization technique for finite ionic conductor chain in periodic boundary conditions. One dimens…
Proportionate vs disproportionate distribution of wealth of two individuals in a tempered Paretian ensemble
G. Oshanin, Yu. Holovatch, G. Schehr
We study the distribution P(ω) of the random variable ω= x_1/(x_1 + x_2), where x_1 and x_2 are the wealths of two individuals selected at random from the same tempered Paretian en…
Shapes of macromolecules in good solvents: field theoretical renormalization group approach
V. Blavatska, C. von Ferber, Yu. Holovatch
In this paper, we show how the method of field theoretical renormalization group may be used to analyze universal shape properties of long polymer chains in porous environment. So…
Magnetism and superconductivity at LAO/STO-interfaces: the role of Ti 3d interface electrons
N. Pavlenko, T. Kopp, E. Y. Tsymbal +2
Ferromagnetism and superconductivity are in most cases adverse. However, recent experiments reveal that they coexist at interfaces of LaAlO3 and SrTiO3. We analyze the magnetic sta…
Two-state Bose-Hubbard model in the hard-core boson limit
I. V. Stasyuk, O. V. Velychko
Phase transition into the phase with Bose-Einstein (BE) condensate in the two-band Bose-Hubbard model with the particle hopping in the excited band only is investigated. Instabilit…
Quantum Heisenberg antiferromagnet on low-dimensional frustrated lattices
Oleg Derzhko, Taras Krokhmalskii, Johannes Richter
Using a lattice-gas description of the low-energy degrees of freedom of the quantum Heisenberg antiferromagnet on the frustrated two-leg ladder and bilayer lattices we examine the…
Control of polymer gel surface pattern formation and its three dimensional measurement method
T. Mizoue, Y. Aoki, M. Tokita +3
We report the controllability of a gelation surface pattern formation. Recently, we have found and studied a novel kind of pattern formation that occurs during a radical polymeriza…
