The orientations of galaxy groups and formation of the Local Supercluster
Wlodzimierz Godlowski, Piotr Flin
We analysed the orientation of galaxy groups in the Local Supercluster (LSC). It is strongly correlated with the distribution of neighbouring groups in the scale till about 20 Mpc.…
Microstructure reconstruction using entropic descriptors
R. Piasecki
A multi-scale approach to the inverse reconstruction of a pattern's microstructure is reported. Instead of a correlation function, a pair of entropic descriptors (EDs) is proposed…
Schur Multipliers and Spherical Functions on Homogeneous Trees
Uffe Haagerup, Troels Steenstrup, Ryszard Szwarc
Let X be a homogeneous tree of degree q+1 (for q between 2 and infinity) and let f be a complex function on X times X for which f(x,y) only depend on the distance between x and y i…
Lévy flights in inhomogeneous environments
Piotr Garbaczewski, Vladimir Stephanovich
We study the long time asymptotics of probability density functions (pdfs) of Lévy flights in different confining potentials. For that we use two models: Langevin - driven and (Lév…
The smallest eigenvalue of Hankel matrices
Christian Berg, Ryszard Szwarc
Let H_N=(s_{n+m}),n,m\le N denote the Hankel matrix of moments of a positive measure with moments of any order. We study the large N behaviour of the smallest eigenvalue lambda_N o…
Levy flights in confining potentials
Piotr Garbaczewski, Vladimir Stephanovich
We analyze confining mechanisms for Lévy flights. When they evolve in suitable external potentials their variance may exist and show signatures of a superdiffusive transport. Two c…
Statistical mechanics characterization of spatio-compositional inhomogeneity
Ryszard Piasecki
On the basis of a model system of pillars built of unit cubes, a two-component entropic measure for the multiscale analysis of spatio-compositional inhomogeneity is proposed. It qu…
The Suslinian number and other cardinal invariants of continua
T. Banakh, V. V. Fedorchuk, J. Nikiel +1
By the {\em Suslinian number} $\Sln(X)$ of a continuum we understand the smallest cardinal number such that contains no disjoint family $\C$ of non-degenerate subcontin…
Quantum critical point in high-temperature superconductors
V. R. Shaginyan, M. Ya. Amusia, K. G. Popov +1
Recently, in high-T_c superconductors (HTSC), exciting measurements have been performed revealing their physics in superconducting and pseudogap states and in normal one induced by…
Energy scales and magnetoresistance at a quantum critical point
V. R. Shaginyan, M. Ya. Amusia, A. Z. Msezane +2
The magnetoresistance (MR) of CeCoIn_5 is notably different from that in many conventional metals. We show that a pronounced crossover from negative to positive MR at elevated temp…
Magnetic-field-induced reentrance of Fermi-liquid behavior and spin-lattice relaxation rates in YbCu_{5-x}Au_x
V. R. Shaginyan, A. Z. Msezane, K. G. Popov +1
A strong departure from Landau-Fermi liquid (LFL) behavior have been recently revealed in observed anomalies in both the magnetic susceptibility and the muon and …
Levy flights and Levy -Schroedinger semigroups
Piotr Garbaczewski
We analyze two different confining mechanisms for Lévy flights in the presence of external potentials. One of them is due to a conservative force in the corresponding Langevin equa…
Entropic descriptor of a complex behaviour
R. Piasecki, A. Plastino
We propose a new type of entropic descriptor that is able to quantify the statistical complexity (a measure of complex behaviour) by taking simultaneously into account the average…
Stable topological textures in a classical 2D Heisenberg model
E. G. Galkina, E. V. Kirichenko, B. A. Ivanov +1
We show that stable localized topological soliton textures (skyrmions) with topological charge exist in a classical 2D Heisenberg model of a ferromagnet with uniaxi…
