Squeezed states and quantum chaos

Kirill N. Alekseev, Dima S. Primak

We examine the dynamics of a wave packet that initially corresponds to a coherent state in the model of quantum kicked rotator. This main model of quantum chaos, which allows for a…

Excitons in quantum-ring structures in a magnetic field: Optical properties and persistent currents

A. O. Govorov, A. V. Kalameitsev, R. Warburton +2

We study theoretically the magnetic field effect on a neutral, but polarizable exciton confined in quantum-ring structures. For excitons with a nonzero dipole moment, a novel magne…

Electron-electron interaction in multiwall carbon nanotubes

A. I. Romanenko, A. V. Okotrub, O. B. Anikeeva +4

Magnetic susceptibility of pristine and brominated arc-produced sample of multiwall carbon nanotubes was measured from 4.2 to 400 K. An additional contribution to diama…

Anomalies in heat capacity of YBa_2Cu_3O_{6+x} in normal state

V. N. Naumov, G. I. Frolova, V. V. Nogteva +2

The temperature dependence of heat capacity for the samples of 90 K phase of YBa_2Cu_3O_{6+x} with x = 0.85, 0.90 and 0.95 was investigated above T_c. For separating the heat capac…

Crystal Chemical Estimation of Possible Exceeding of Tc of 77 K in Diborides

L. M. Volkova, S. A. Polyshchuk, S. A. Magarill +1

We establish the empirical correlation between Tc and crystal chemical parameters in diborides. Our results suggest that Tc of diborides can be higher 77K.

A class of integrable lattices and KP hierarchy

A. K. Svinin

We introduce a class of integrable -field first-order lattices together with corresponding Lax equations. These lattices may be represented as consistency condition for auxiliar…

Differential constraints for the Kaup -- Broer system as a reduction of the 1D Toda lattice

A. K. Svinin

It is shown that some special reduction of infinite 1D Toda lattice gives differential constraints compatible with the Kaup -- Broer system. A family of the travelling wave solutio…

Photon-Reggeon Interaction Vertices in the Nla

V. S. Fadin, D. Yu. Ivanov, M. I. Kotsky

We calculate the effective vertices for the quark-antiquark and the quark-antiquark-gluon production in the virtual photon - Reggeized gluon interaction. The last vertex is conside…

Compact vacuum phototriodes for operation in strong magnetic field

M. N. Achasov, B. A. Baryshev, K. I. Beloborodov +8

The results of tests of 1'' vacuum phototriodes in a magnetic field up to 4.5 T are presented. It was found that output amplitude decreases by about 6 % per tesla in the magnetic f…
