Phonon assisted tunneling in Josephson junctions
E. G. Maksimov, P. I. Arseyev, N. S. Maslova
The expression for additional subgap current in the presence of electron-phonon interaction is derived. We show that the phonon assisted tunneling leads to appearance of peaks on c…
Decoherence and continuous measurements: Phenomenology and models
Michael B. Mensky
Decoherence of a quantum system induced by the interaction with its environment (measuring medium) may be presented phenomenologically as a continuous (or repeated) fuzzy quantum m…
Vacuum amplification of the high-frequency electromagnetic radiation
G. A. Vilkovisky
When an electrically charged source is capable of both emitting the electromagnetic waves and creating charged particles from the vacuum, its radiation gets so much amplified that…
Two-dimensional Cooling of Ion Beams in Storage Rings by Narrow Broad-Band Laser Beams
E. G. Bessonov, K. -J. Kim, F. Willeke
A new scheme for the two-dimensional cooling of ion beams in storage rings is suggested in which ions interact with a counterpropagating broad-band laser beam. The interaction regi…
The Electronics of the H1 Lead/Scintillating-Fibre Calorimeters
H1 SpaCal Group, R. -D. Appuhn et al
The electronic system developed for the SpaCal lead/scintillating-fibre calorimeters of the H1 detector in operation at the HERA ep collider is described in detail and the performa…
Temperature dependence of electric resistance and magnetoresistance of pressed nanocomposites of multilayer nanotubes with the structure of nested cones
V. I. Tsebro, O. E. Omel'yanovskii, E. F. Kukovitskii +3
Bulk samples of carbon multilayer nanotubes with the structure of nested cones (fishbone structure) suitable for transport measurements, were prepared by compressing under high pre…
Field-asymmetric transverse magnetoresistance in a nonmagnetic quantum-size structure
A. A. Gorbatsevich, V. V. Kapaev, Yu. V. Kopaev +3
A new phenomenon is observed experimentally in a heavily doped asymmetric quantum-size structure in a magnetic field parallel to the quantum-well layers - a transverse magnetoresis…
Maximum Metallic Conductivity in Si-MOS Structures
V. M. Pudalov, G. Brunthaler, A. Prinz +1
We found that the conductivity of the two-dimensional electron system in Si-MOS structures is limited to a maximum value, G_{max}, as either density increases or temperature decrea…
Measurement of D* Meson Cross Sections at HERA and Determination of the Gluon Density in the Proton using NLO QCD
C. Adloff
With the H1 detector at the ep collider HERA, D* meson production cross sections have been measured in deep inelastic scattering with four-momentum transfers Q^2>2 GeV2 and in phot…
Open inflation from quantum cosmology with a strong nonminimal coupling
A. O. Barvinsky
We propose the mechanism of quantum creation of the open Universe in the observable range of values of . This mechanism is based on the no-boundary quantum state with the Hawkin…
Conformal Field Theory in Conformal Space
C. R. Preitschopf, M. A. Vasiliev
We present a new framework for a Lagrangian description of conformal field theories in various dimensions based on a local version of d+2-dimensional conformal space. The results i…
Decoherence in quantum cosmology at the onset of inflation
A. Barvinsky, A. Kamenshchik, C. Kiefer +1
We calculate the reduced density matrix for the inflaton field in a model of chaotic inflation by tracing out degrees of freedom corresponding to various bosonic fields. We find a…
The evolution of a supermassive binary caused by an accretion disc
P. B. Ivanov, J. C. B. Papaloizou, A. G. Polnarev
The interaction of a massive binary and a non-self-gravitating circumbinary accretion disc is considered. The shape of the stationary twisted disc produced by the binary is calcula…

H. W. Braden, A. Marshakov, A. Mironov +1
The prepotential and spectral curve are described for a smooth interpolation between an enlarged N=4 SUSY and ordinary N=2 SUSY Yang-Mills theory in four dimensions, obtained by co…

V. V. Alekseev, S. N. Cherepnya, L. V. Fil'kov +1
The possibility of observation of supernarrow dibaryons, decay of which into two nucleons forbidden by the Pauli principle, produced in processes of charged pion photoproduction by…
Angular pattern of minijet transverse energy flow in hadron and nuclear collisions
A. V. Leonidov, D. M. Ostrovsky
The azimuthal asymmetry of minijet system produced at the early stage of nucleon-nucleon and nuclear collisions in a central rapidity window is studied. We show that in pp collisio…
