Path Group in gauge theory and gravity
Michael B. Mensky
Applications of the Path Group (consisting of classes of continuous curves in Minkowski space-time) to gauge theory and gravity are reviewed. Covariant derivatives are interpreted…
Entanglement in the Process of Stimulated Brillouin Scattering of Light
S. V. Kuznetsov, A. V. Kyusev, O. V. Man'ko +1
The process of stimulated Brillouin scattering is described by the model of two-dimensional oscillator. The phenomenon of entanglement which appears in the photon-phonon modes afte…
Canonical form of Euler-Lagrange equations and gauge symmetries
B. Geyer, D. M. Gitman, I. V. Tyutin
The structure of the Euler-Lagrange equations for a general Lagrangian theory is studied. For these equations we present a reduction procedure to the so-called canonical form. In t…
Detection of Giant Pulses from the Pulsar PSR B1112+50
A. A. Ershov, A. D. Kuzmin
We detected giant pulses from the pulsar PSR B1112+50. A pulse with an intensity that is a factor of 30 or more higher than the intensity of the average pulse is encountered approx…
The Quantum Theory of Conductivity of Spatially - Heterogeneous Systems
I. G. Lang, L. I. Korovin, J. A. de la Cruz Alcaz +1
The quantum theory of conductivity of semiconductor objects, to which the quantum wells, wires and dots concern, is constructed. Average values of current and charge densities, ind…
Quantum continuous measurements, dynamical role of information and restricted path integrals
Michael B. Mensky
The restricted-path-integral (RPI) theory of continuous quantum measurements including the evolution of the measured systems and phenomenon of decoherence is reviewed. The measured…
Current Fluctuations and Electron-Electron Interactions in Coherent Conductors
A. V. Galaktionov, D. S. Golubev, A. D. Zaikin
We analyze current fluctuations in mesoscopic coherent conductors in the presence of electron-electron interactions. In a wide range of parameters we obtain explicit universal depe…
Quantum dissipative systems from theory of continuous measurements
Michael B. Mensky, Stig Stenholm
We apply the restricted-path-integral (RPI) theory of non-minimally disturbing continuous measurements for correct description of frictional Brownian motion. The resulting master e…
Quantum Measurement Problem and Systems Selfdescription in Operators Algebras Formalism
S. Mayburov
Quantum Measurement problem studied in Information Theory approach of systems selfdescription which exploits the information acquisition incompleteness for the arbitrary informatio…
Quantum oscillations in two coupled charge qubits
Yu. A. Pashkin, T. Yamamoto, O. Astafiev +3
Despite an apparent progress in implementing individual solid-state qubits, there have been no experimental reports so far on multi-bit gates required for building a real quantum c…
String Theory or Field Theory?
A. Marshakov
The status of string theory is reviewed, and major recent developments - especially those in going beyond perturbation theory in the string theory and quantum field theory framewor…
Magnetic fields in AGNs and microquasars
A. F. Zakharov, N. S. Kardashev, V. N. Lukash +1
Observations of AGNs and microquasars by ASCA, RXTE, Chandra and XMM-Newton indicate the existence of wide X-ray emission lines of heavy ionized elements in their spectra. The emis…
Quantum control and the Strocchi map
R. Vilela Mendes, V. I. Man'ko
Identifying the real and imaginary parts of wave functions with coordinates and momenta, quantum evolution may be mapped onto a classical Hamiltonian system. In addition to the sym…
Laser Cooling of Nuclear Beams in Storage Rings
E. G. Bessonov, E. V. Tkalya
Laser cooling of nuclear beams in storage rings is discussed. The main properties of nuclei with isomeric levels in the range E<50 keV are presented.
Graviton oscillations in the two-brane world
Andrei Barvinsky, Alexander Kamenshchik, Claus Kiefer +1
We study the braneworld effective action in the two-brane Randall-Sundrum model. In the framework of this essentially-nonlocal action we reveal the origin of an infinite sequence o…

HERMES collaboration, A. Airapetian
Single-spin asymmetries have been measured for semi-inclusive electroproduction of , , and mesons in deep-inelastic scattering off a longitudinally polarised…
Evolution of an open system as a continuous measurement of this system by its environment
Michael B. Mensky
The restricted-path-integral (RPI) description of a continuous quantum measurement is rederived starting from the description of an open system by the Feynman-Vernon influence func…
Proximity-induced screening and its magnetic breakdown in mesoscopic hybrid structures
A. V. Galaktionov, A. D. Zaikin
We derive a general microscopic expression for the non-linear diamagnetic current in a clean superconductor-insulator-normal metal structure with an arbitrary interface transmissio…
Complex Curve of the Two Matrix Model and its Tau-function
Vladimir A. Kazakov, Andrei Marshakov
We study the hermitean and normal two matrix models in planar approximation for an arbitrary number of eigenvalue supports. Its planar graph interpretation is given. The study reve…
