Fluctuation of inverse compressibility for electronic systems with random capacitive matrices
Yshai Avishai, Daniel Berend, Richard Berkovits
This article is concerned with statistics of addition spectra for systems of identical charged particles. A classical model is suggested in order to study fluctuations of Coulomb b…
Anomalous Low Temperature Behavior of Superconducting Nd(1.85)Ce(0.15)CuO(4-y)
L. Alff, S. Meyer, S. Kleefisch +5
We have measured the temperature dependence of the in-plane London penetration depth lambda(T) and the maximum Josephson current Ic(T) using bicrystal grain boundary Josephson junc…
Exact Eigenstates and Magnetic Response of Spin-1 and Spin-2 Vectorial Bose-Einstein Condensates
Masato Koashi, Masahito Ueda
The exact eigenspectra and eigenstates of spin-1 and spin-2 vectorial Bose-Einstein condensates (BECs) are found, and their response to a weak magnetic field is studied and compare…
Contact phenomena in carbon nanotubes
Arkadi A. Odintsov, Yasuhiro Tokura
Poor screening of the long-range Coulomb interaction in one-dimensional carbon nanotubes results in a peculiar picture of contact phenomena. Being brought to a contact with a metal…
Ellipsoidal deformation of vertical quantum dots
D. G. Austing, S. Sasaki, S. Tarucha +3
Addition energy spectra at 0 T of circular and ellipsoidally deformed few-electron vertical quantum dots are measured and compared to results of model calculations within spin-dens…
Phase transitions and the internal noise structure of nonlinear Schrödi nger equation solitons
M. J. Werner, S. R. Friberg
We predict phase-transitions in the quantum noise characteristics of systems described by the quantum nonlinear Schrödinger equation, showing them to be related to the solitonic fi…
