Aharonov-Bohm-Type Oscillations of Thermopower in a Quantum Dot Ring Geometry
We investigate Aharonov-Bohm-type oscillations of the thermopower of a
quantum dot embedded in a ring for the case when the interaction between
electrons can be neglected. The thermopower is shown to be strongly flux
dependent, and typically the amplitude of oscillations exceeds the background
value. It is also shown to be essentially dependent on the phase of the
scattering matrix which is determined by the experimental geometry and is not
known in the given experiment. Two procedures to compare theory and experiment
are proposed.Comment: Revtex, 5 figures include
Local Density of States in a Dirty Normal Metal connected to a Superconductor
A superconductor in contact with a normal metal not only induces
superconducting correlations, known as proximity effect, but also modifies the
density of states at some distance from the interface. These modifications can
be resolved experimentally in microstructured systems. We, therefore, study the
local density of states of a superconductor - normal metal
heterostructure. We find a suppression of at small energies, which
persists to large distances. If the normal metal forms a thin layer of
thickness , a minigap in the density of states appears which is of the
order of the Thouless energy . A magnetic field suppresses
the features. We find good agreement with recent experiments of Gu\'eron {\it
et al.}Comment: 5 pages, RevTeX, 7 Figures (included), Submitted to PRB. Revised

Frequency Dependence of Magnetopolarizability of Mesoscopic Grains
We calculate average magnetopolarizability of an isolated metallic sample at
frequency comparable to the mean level spacing . The frequency
dependence of the magnetopolarizability is described by a universal function of
