Static, non-SUSY p-branes in diverse dimensions
(IOP Publishing Ltd, 2005-02-01)
We give explicit constructions of static, non-supersymmetric p-brane (for p ≤ d−4, where d is the space-time dimensionality and including p = −1 or D-instanton) solutions of type II supergravities in diverse dimensions. ...
High-performance mid-infrared quantum dot infrared photodetectors
(IOP Publishing Ltd, 2005-07-07)
Quantum dot infrared photodetectors (QDIPs) have emerged as attractive devices for sensing long wavelength radiation. Their principle of operation is based on intersublevel transitions in quantum dots (QDs). Three-dimensional ...
A skewed-momenta method to efficiently generate conformational-transition trajectories
(The American Institute of Physics, 2005-08-15)
We present a novel computational method, the skewed-momenta method (Skew’M), which applies a bias to the Maxwell distribution of initial momenta used to generate ensembles of trajectories. As a result, conformational ...
A method for normalization of X-ray absorption spectra

Methanofullerene-coated tetrabenzoporphyrin organic field-effect transistors
(The American Institute of Physics, 2005-10-24)
Organic field-effect transistors (OFETs) using a solution-processable form of the organic semiconductor tetrabenzoporphyrin were fabricated with a top coating of a soluble nn-type organic semiconductor. The top coating was ...
Non-associative gauge theory and higher spin interactions
(IOP Publishing Ltd, 2005-03-01)
We give a framework to describe gauge theory on a certain class of commutative but non-associative fuzzy spaces. Our description is in terms of an abelian gauge connection valued in the algebra of functions on the ...
The extent of quantum critical fluctuations into the heavy-fermion phase: A neutron scattering study of Ce(Ru1−xFex)2Ge2Ce(Ru1−xFex)2Ge2
(The American Institute of Physics, 2005-05-15)
We present inelastic neutron scattering measurements on the heavy-fermion compound Ce(Ru1−xFex)2Ge2Ce(Ru1−xFex)2Ge2 (x = 0.87)(x=0.87). This composition is close to the quantum critical point (QCP) compound (x = 0.76)(x=0.76) ...
The antiferromagnetic/paramagnetic transition in mixed-spin compounds R2BaNiO5
(EDP Sciences; EDP Sciences/Società Italiana di Fisica/Springer-Verlag, 2005-04)
We present an extensive Quantum Monte Carlo study of the magnetic properties ofthe mixed-spin quantum systems R2BaNiO5 (R= magnetic rare earth)which show coexistence of 3-dimensional magnetic long-range orderwith 1-dimensional ...
The dynamical Casimir effect in a periodically changing domain: a dynamical systems approach
(IOP Publishing Ltd, 2005-03-01)
We study the problem of the behaviour of a quantum massless scalar field in the space between two parallel infinite perfectly conducting plates, one of them stationary, the other moving periodically. We reformulate the ...
TOPICAL REVIEW: Microfluidics for flow cytometric analysis of cells and particles
(IOP Publishing Ltd, 2005-06-01)
This review describes recent developments in microfabricated flow cytometers and related microfluidic devices that can detect, analyze, and sort cells or particles. The high-speed analytical capabilities of flow cytometry ...
