The growth of polycrystalline GaAs thin films by laser introduced photodecomposition is reported. The process involves the mixture of gallium and arsenic metalorganic compounds.
We identify odd and even parity states and measure transient photomodulation spectra of Frenkel excitons in alpha-hexathiophene single crystals.
We have measured the temperature dependence of the fractional quantum Hall effect at filling factors v = 1/3, 2/3, and 2/5 in tetracene in order to determine the associated excitation gaps.
Simulation of the kinetic Alfven wave is performed using a 2-1/2 dimensional macroscale particle [magnetohydrodynamic (MHD) scale kinetic] simulation code.

Communication by means of optical fibers requires that light energy can be coupled into the fiber in an efficient way.
Communications systems using light waves as the carrier of information need some means of signal processing at the end terminals and perhaps also at intermediate repeater points along the transmiss
At the Yang-Lee edge singularity, finite-size scaling behavior is used to measure the low-lying excitation spectrum of the Ising quantum spin chain for free boundary conditions.
This paper studies the Yang-Lee edge singularity of 2-dimensional(2D) Ising model through a quantum spin chain.
We consider spatially localized and time periodic solutions to discrete extended Hamiltonian dynamical systems (coupled systems of infinitely many "oscillations" which conserve total energy).
