Wave breaking and the generation of undular bores in an integrable shallow-water system
G. A. El, R. H. J. Grimshaw, A. M. Kamchatnov
The generation of an undular bore in the vicinity of a wave-breaking point is considered for the integrable Kaup-Boussinesq shallow water system. In the framework of the Whitham mo…
Change in the Nuclear Moment of Inertia at the Number of Neutrons N = 98 and Isotopic Shift of Atomic Levels
A. M. Kamchatnov, V. G. Nosov
From analysis of experimental data on nuclear rotation, it is found that the so-called rigid-body value of the nuclear moment of inertia and the nuclear-radius values associated wi…
Topological soliton in magnetohydrodynamics
A. M. Kamchatnov
We use the Hopf mapping to construct a magnetic configuration consisting of closed field lines, each of which is linked with all the other ones. We obtain in this way a solution of…
Thermodynamic inequalities for nuclear rotation
V. G. Nosov, A. M. Kamchatnov
The strictly reversible, thermodynamically equilibrium nature of the free rotation of a body makes it possible to obtain a number of bounds on the rotational characteristics within…
Relation between the critical spin and angular velocity of a nucleus immediately after backbending
V. G. Nosov, A. M. Kamchatnov
In nonspherical nuclei at the relationship between the angular momentum and angular velocity immediately after backbending is the same as in the limiting case $J - J_…
Dynamics of Bose-Einstein condensates in cigar-shaped traps
A. M. Kamchatnov, V. S. Shchesnovich
Gross-Pitaevskii equation for Bose-Einstein condensate confined in elongated cigar-shaped trap is reduced to an effective system of nonlinear equations depending on only one space…
