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
Energetic disorder at the metal/organic semiconductor interface
The physics of organic semiconductors is dominated by the effects of
energetic disorder. We show that image forces reduce the electrostatic
component of the total energetic disorder near an interface with a metal
electrode. Typically, the variance of energetic disorder is dramatically
reduced at the first few layers of organic semiconductor molecules adjacent to
the metal electrode. Implications for charge injection into organic
semiconductors are discussed.Comment: 9 pages, 2 figure
New global stability estimates for the Gel'fand-Calderon inverse problem
We prove new global stability estimates for the Gel'fand-Calderon inverse
problem in 3D. For sufficiently regular potentials this result of the present
work is a principal improvement of the result of [G. Alessandrini, Stable
determination of conductivity by boundary measurements, Appl. Anal. 27 (1988),
153-172]
