A cosmological bound on mass difference
We demonstrate that CPT-violation due to mass difference generates
a non-zero photon mass. As a result the cosmological bounds on the photon mass
lead to the bounds on mass difference which are at least by 10 orders
of magnitude stronger than the direct experimental bound.Comment: 8 page
New Variational Principles in Classical and Semiclassical Mechanics
We demonstrate that reciprocal Maupertuis' Principle is the classical limit
of Schr\"{o}dinger's Variational Principle in Quantum Mechanics.Comment: To appear in the Michael Marinov Memorial Volume, "Multiple facets of
quantization and supersymmetry", edited by M. Olshanetsky and A. Vainshtein
(World Scientific). We corrected TEX style of the paper so that the names of
both authors can be seen in PS file no
