Structure of the 12j and 15j coefficients in the Bargmann approach
(The American Institute of Physics, 1974-09)
Generating functions of the 12j and 15j angular momentum recoupling coefficients are computed explicitly in the Bargmann formalism. Symmetry properties are deduced therefrom. A geometrical Möbius strip representation ...
Pseudomorphic InGaAs base ballistic hot‐electron device
(The American Institute of Physics, 1988-11-14)
We report the first successful incorporation of a pseudomorphic InGaAs base in a ballistic hot‐electron device. The device, with a 28‐nm‐thick In0.15Ga0.85As base, had a collector‐base breakdown voltage of 0.55 V and a ...
Interstellar Pathfinder — A Mission to the Inner Edge of the Interstellar Medium
(The American Institute of Physics, 2003-09-02)
Interstellar Pathfinder (ISP), our first step into the interstellar medium, is a scientific investigation to study the outer boundary of our heliosphere and the interstellar matter that flows into it. A wind of interstellar ...
Growth and properties of quasiperiodic heterostructures
(Elsevier, 1987-02-02)
We have recently demonstrated the MBE growth of heterostructures in which layers of GaAs and AlAs were deposited in a Fibonacci sequence. This yields a quasiperiodic structure with the ratio of incommensurate periods equal ...
Resonant energy transfer in electron-driven proton pumps
(WILEY-VCH Verlag, 2008-01)
We examine proton and electron transport in living cell membranes and show that the Coulomb interaction leads to a resonant energy transfer, from the electrons to protons during their simultaneous tunnelings, which allows ...
Functional clustering in hippocampal cultures: relating network structure and dynamics
(2010-10)
In this work we investigate the relationship between gross anatomic structural network properties, neuronal dynamics and the resultant functional structure in dissociated rat hippocampal cultures. Specifically, we studied ...
Cosmological Magnetohydrodynamic Simulations of Cluster Formation with Anisotropic Thermal Conduction
(IOP Publishing, 2011)
The intracluster medium (ICM) has been suggested to be buoyantly unstable in the presence of magnetic field and anisotropic thermal conduction. We perform first cosmological simulations of galaxy cluster formation that ...
Brane-world Kaluza–Klein reductions and branes on the brane
(The American Institute of Physics, 2001-07)
We present a systematic study of a new type of consistent “brane-world Kaluza–Klein reduction,” which describes fully nonlinear deformations of codimension one objects that arise as solutions of a large class of gauged ...
