On the Theory of Quantum Oscillations of the Elastic Moduli in Layered Conductors
In this paper we study theoretically how the local geometry of the Fermi
surface (FS) of a layered conductor can affect quantum oscillations in the
thermodynamic observables. We introduce a concrete model of the FS of a layered
conductor. The model permits us to analyze the characteristic features of
quantum oscillatory phenomena in these materials which occure due to local
anomalies of the Gaussian curvature of the FS. Our analysis takes into account
strong interaction among quasiparticles and we study the effect of this
interaction within the framework of Fermi-liquid theory. We show that the
Fermi-liquid interaction strongly affects the density of states of
quasiparticles (DOS) on the FS. As a result DOS can have singularities near the
peaks of its oscillations in a strong magnetic field. These singularities can
be significantly strengthened when the FS of the layered conductor is locally
flattened. This can lead to magnetic and lattice instabilities of a special
kind which are considered in the final part of the work.Comment: 11 pages, 2 figures, minor changes in the title are made, published

Decrease of atmospheric neutron counts observed during thunderstorms.
We report here, in brief, some results of the observation and analysis of sporadic variations of atmospheric thermal neutron flux during thunderstorms. The results obtained with unshielded scintillation neutron detectors show a prominent flux decrease correlated with meteorological precipitations after a long dry period. No observations of neutron production during thunderstorms were reported during the three-year period of data recording
