High spatial resolution imaging with THz pulses is implemented on the base of the time domain spectroscopy system.
Biological computers, our brains, solve problems such as recognizing speech with little apparent effort, while electronic computers do this still very poorly.
Raman measurements in the 1.5 - 20 cm -1 energy range were performed on single crystals of Sr14-xCaxCu24O41.
We present a theory of the collective excitation spectrum in a fractional quantum Hall effect regime, in analogy with Feynman's theory for helium.
We consider a semiconductor of arbitrary dimension subject to a strong monochromatic laser beam in the transparency region below the exciton resonance.
We report the observation of sharp plasmon and magnetoplasmon modes in ultra-low density 2D electron systems.
We report inelastic light scattering measurements of dispersive spin and charge density excitations in dilue 2D electron systems reaching densities less than 10 sup (10) cm lsup (-2).
Standard weak-coupling methods are used to calculate the excitation spectrum and the instabilities of the metallic phase of a three- band model for the copper-oxide superconductors with both intra-
We showed in this chapter low temperature Raman data on phononic and magnetic excitations in SrCu2(BO3)2.
A three-band extended Hubbard model for CuO sub 2 planes is explored within a weak-coupling approximation scheme.
