Supertraces on the algebra of observables of the rational Calogero model based on the classical root system
S. E. Konstein
A complete set of supertraces on the algebras of observables of the rational Calogero models with harmonic interaction based on the classical root systems of B_N, C_N and D_N types…
Enhanced Correlations and Wide Charge Distributions in Pion Production
I. V. Andreev
Unusual phenomena in pion production are considered.It is argued that pions may be in a squeezed state having enhanced identical pion correlations. Charge distribution in soft chir…
Charge Distribution in Soft Chiral Pion Bremsstrahlung
I. V. Andreev, M. Biyajima, V. A. Nechitailo +1
Bremsstrahlung of soft chiral pions in high-energy processes is considered. The distribution over number of neutral and charged pions is shown to obey the inverse square root law.…
Charge Distribution in Chiral Pion Bremsstrahlung
I. V. Andreev
It is argued that distribution over the number of charged and neutral soft chiral pions are very broad if they are emitted coherently.
Determination of the tunneling electron-phonon spectral function in high-Tc superconductors with energy dependence of the normal density of states
R. S. Gonnelli, G. A. Ummarino, V. A. Stepanov
We discuss the limits and the correct utilization of the standard program for the inversion of Eliashberg equations and the determination of the electron-phonon spectral function a…
Comment on "Dynamical Chern-Simons term generation at finite density" and "Chern-Simons term at finite density"
Vadim Zeitlin
We comment on the calculation of the Chern-Simons coefficient in (2+1)-dimensional gauge theories at finite chemical potential made by A.N.Sissakian, O.Yu.Shevchenko and S.B.Solgan…
Possibility of observation of supernarrow dibaryons with symmetric wave function in reactions
V. M. Alekseyev, S. N. Cherepnya, L. V. Fil'kov +1
The possibility of obsevation of supernarrow dibaryons with symmetric wave function in reactions and is studied. These dibaryons satisfy the c…
Ballistic Transport in Superconducting Weak Links in a Microwave Field
Uwe Gunsenheimer, A. D. Zaikin
Nonequilibrium effects and their impact on a charge transport in superconducting ballistic weak links biased by an ac voltage are investigated within the framework of the Keldysh t…
Evidence for strong electron-phonon coupling and polarons in the optical response of La_{2-x}Sr_xCuO_4
O. V. Dolgov, H. J. Kaufmann, E. K. H. Salje +1
The normal state optical response of La_{2-x}Sr_xCuO_4 is found to be consistent with a simple multi-component model, based on free carriers with strong electron-phonon interaction…
Different Aspects of Relativistic Toda Chain
S. Kharchev, A. Mironov, A. Zhedanov
We demonstrate that the generalization of the relativistic Toda chain (RTC) is a special reduction of two-dimensional Toda Lattice hierarchy (2DTL). We also show that the RTC is ga…
Quantum origin of the early inflationary Universe
A. O. Barvinsky, A. Yu. Kamenshchik, I. V. Mishakov
We give a detailed presentation of a recently proposed mechanism of generating the energy scale of inflation by loop effects in quantum cosmology. We discuss the quantum origin of…
Rigidly Rotating Strings in Stationary Spacetimes
V. Frolov, S. Hendy, J. P. De Villiers
In this paper we study the motion of a rigidly rotating Nambu-Goto test string in a stationary axisymmetric background spacetime. As special examples we consider the rigid rotation…
Factorial and Cumulant Moments in a Simple Cascade Model
A. V. Leonidov, D. M. Ostrovsky
Factorial and cumulant moments in a simple cascade models are considered. Their characteristic features are shown to be similar to those observed in QCD jets.
Properties of Squeezed-State Excitations
Vladimir I. Man'ko, Alfred Wünsche
The photon distribution function of a discrete series of excitations of squeezed coherent states is given explicitly in terms of Hermite polynomials of two variables. The Wigner an…
f-Oscillators and Nonlinear Coherent States
V. I. Man'ko, G. Marmo, E. C. G. Sudarshan +1
The notion of f-oscillators generalizing q-oscillators is introduced. For classical and quantum cases, an interpretation of the f-oscillator is provided as corresponding to a speci…
On Electrostatic Positron Acceleration In The Accretion Flow Onto Neutron Stars
R. Turolla, S. Zane, A. Treves +1
As first shown by Shvartsman (1970), a neutron star accreting close to the Eddington limit must acquire a positive charge in order for electrons and protons to move at the same spe…
Higher-Spin Gauge Theories in Four, Three and Two Dimensions
Mikhail Vasiliev
We review the theory of higher-spin gauge fields in four and three space-time dimensions and present some new results on higher-spin gauge interactions of matter fields in two dime…

A measurement of the inclusive cross section for the deep-inelastic scattering of positrons off protons at HERA is presented at momentum transfers and…
Statistical Tests for CHDM and \LambdaCDM Cosmologies
S. Ghigna, S. Borgani, M. Tucci +3
We apply several statistical estimators to high-resolution N-body simulations of two currently viable cosmological models: a mixed dark matter model, having contributed b…
