Statistical Mechanics of Assemblies of Coupled Oscillators
(The American Institute of Physics, 1965-04)
It is shown that a system of coupled harmonic oscillators can be made a model of a heat bath. Thus a particle coupled harmonically to the bath and by an arbitrary force to a fixed center will (in an appropriate limit) ...
Conductivity of a system of metallic particles dispersed in an insulating medium
(The American Institute of Physics, 1973-06)
The variation of the conductivity of metal‐particle—insulator systems with the volume percent of metal is explained in terms of an ``effective medium'' theory.
Momentum, heat and mass transfer in logarithmic spiral flows of incompressible viscous fluids
(Elsevier, 1964-10)
This paper presents a theoretical investigation of the transfer of momentum, heat and mass in incompressible viscous flow through a logarithmic spiral channel. The velocity, temperature and concentration profiles are ...
Synthesis and regional mouse brain distribution of [11C]Nisoxetine, a norepinephrine uptake inhibitor
(Elsevier, 1989)
Nisoxetine, a selective and high affinity (IC50 = 1 nM) inhibitor of NE reuptake, has been radiolabeled in high specific activity (> 600 Ci/mmol) by the alkylation of the nor-methyl precursor with [11C]CH3I. Synthetic ...
Theory of photoluminescence in quantum wells in the presence of transverse electric field: Monte Carlo approach
(The American Institute of Physics, 1986-04-15)
The Monte Carlo approach is used to study the quasibound electron and hole ground‐state levels in a quantum well in the presence of a transverse electric field. A criteria is developed to ensure that the ground state is a ...
Quantum phase transition and sliding Luttinger liquid in coupled t–J chains
(IOP Publishing Ltd, 2006-05-01)
Using a recently proposed perturbative numerical renormalization-group algorithm, we explore the connection between quantum criticality and the emergence of Luttinger liquid physics in t–J chains coupled by frustrated ...
Jet production by a gluon source in QCD
(Elsevier, 1978-12-25)
The properties of jets produced by a gluon source are examined in QCD. We give a simple derivation of the jet opening angle (up to an undetermined constant) using arguments of general applicability. At asymptotic energies, ...
The influences of roughness on film thickness measurements by Mueller matrix ellipsometry
(The American Institute of Physics, 1994-09)
The accuracy of measurement of the thickness of uniform thin films on solid substrates by null ellipsometry is severely limited when the substrate is rough. It is impossible to separate these two effects experimentally ...
Chlorite control of correlations between strain and anisotropy of magnetic susceptibility
(Elsevier, 1990)
Anisotropy of magnetic susceptibility (AMS) has in the past been used as an indicator of finite strain; mathematical relationships between the measured AMS ellipsoid and the finite strain ellipsoid in slates are numerous. ...
Cosmic string in the van Stockum cylinder
(IOP Publishing Ltd, 2003-05-07)
The low density van Stockum dust solution is extended by including an angular deficit factor. The resulting model describes a rotating Gott–Hiscock string surrounded by an annular dust atmosphere. The interior spacetime ...
