Waterlike thermodynamic anomalies in a repulsive-step potential system
N. V. Gribova, Yu. D. Fomin, Daan Frenkel +1
We report a computer-simulation study of the equilibrium phase diagram of a three-dimensional system of particles with a repulsive step potential. The phase diagram is obtained usi…
Selected problems of baryons spectroscopy: chiral soliton versus quark models
Vladimir B. Kopeliovich
Inconsistency between rigid rotator and bound state models at arbitrary number of colors, rigid rotator -- soft rotator dilemma and some other problems of baryon spectroscopy are d…
System Theoretic Viewpoint on Modeling of Complex Systems: Design, Synthesis, Simulation, and Control
Armen Bagdasaryan
We consider the basic features of complex dynamic and control systems, including systems having hierarchical structure. Special attention is paid to the problems of design and synt…
Masses of light tetraquarks and scalar mesons in the relativistic quark model
D. Ebert, R. N. Faustov, V. O. Galkin
Masses of the ground state light tetraquarks are dynamically calculated in the framework of the relativistic diquark-antidiquark picture. The internal structure of the diquark is t…
Double Pair Production by Ultra High Energy Cosmic Ray Photons
S. V. Demidov, O. E. Kalashev
With use of CompHEP package we've made the detailed estimate of the influence of double e+e- pair production by photons (DPP) on the propagation of ultra high energy electromagneti…
Shape parameters of Galactic open clusters
N. V. Kharchenko, P. Berczik, M. I. Petrov +4
(abridged) In this paper we derive observed and modelled shape parameters (apparent ellipticity and orientation of the ellipse) of 650 Galactic open clusters identified in the ASCC…
Resonant optical electron transfer in one-dimensional multiwell structures
A. V. Tsukanov
We consider coherent single-electron dynamics in the one-dimensional nanostructure under resonant electromagnetic pulse. The structure is composed of two deep quantum wells positio…
Baryon resonances in the mean field approach and a simple explanation of the Theta+ pentaquark
Dmitri Diakonov
We suggest to classify baryon resonances as single-quark states in a mean field, and/or as its collective excitations. Identifying the Roper resonance N(1440), the nucleon resonanc…
Ultimate synchrotron cutoff in gamma-ray spectra of blazars as a signature of the converter mechanism
Boris E. Stern, Yana Y. Tikhomirov
There is a robust upper limit on the energy of synchrotron radiation in high-energy astrophysics: , where is the fine structure constant and the…
HeII->HeI Recombination of Primordial Helium Plasma Including the Effect of Neutral Hydrogen
E. E. Kholupenko, A. V. Ivanchik, D. A. Varshalovich
The HeII->HeI recombination of primordial helium plasma (z = 1500 - 3000) is considered in terms of the standard cosmological model. This process affects the formation of cosmic mi…
Discovery of very low amplitude 9-minute multiperiodic pulsations in the magnetic Ap star HD 75445
O. Kochukhov, S. Bagnulo, G. Lo Curto +1
We present our discovery of pulsational radial-velocity variations in the cool Ap star HD 75445, an object spectroscopically similar to the bright, rapidly-oscillating Ap (roAp) st…
String Functions for Affine Lie Algebras Integrable Modules
Petr Kulish, Vladimir Lyakhovsky
The recursion relations of branching coefficients for a module reduced to a Cartan subalgebra are transformed in order to…
Star-forming cores embedded in a massive cold clump: Fragmentation, collapse and energetic outflows
Martin Hennemann, Stephan M. Birkmann, Oliver Krause +4
The fate of massive cold clumps, their internal structure and collapse need to be characterised to understand the initial conditions for the formation of high-mass stars, stellar s…
Strong-Coupling Constant at Three Loops in Momentum Subtraction Scheme
K. G. Chetyrkin, B. A. Kniehl, M. Steinhauser
In this paper we compute the three-loop corrections to the function in a momentum subtraction (MOM) scheme with a massive quark. The calculation is performed in the background…
Feedback Differential Invariants
Valentin Lychagin
The problem of feedback equivalence for control systems is considered. An algebra of differential invariants and criteria for the feedback equivalence for regular control systems a…
Evidence for two-gap nodeless superconductivity in SmFeAsOF from point-contact Andreev-reflection spectroscopy
D. Daghero, M. Tortello, R. S. Gonnelli +3
Point-contact Andreev-reflection measurements were performed in SmFeAsO_{0.8}F_{0.2} polycrystals with T_c \simeq 53 K. The experimental conductance curves reproducibly exhibit pea…
Toward mode selection in Delta Scuti stars: Regularities in observed and theoretical frequency spectra
M. Breger, P. Lenz, A. A. Pamyatnykh
Only a fraction of the theoretically predicted nonradial pulsation modes have so far been observed in Delta Scuti stars. Nevertheless, the large number of frequencies detected in r…
