High-resolution soft x-ray absorption spectra for the C 1s- > pi * transition were measured in C sub 6 H sub 6 and C sub 6 D sub 6 .
The line width of bulk plasmons in a rapid quench Al(6)Mn quasicrystal is found to increase by ~40% as compared with that observed in a thermally annealed crystalline Al(6)Mn sample.
We report an experimental verification of Berry's topological phase for the photon, i.e., the nonintegrable phase factor in quantum mechanics.
To ascertain the role of bromination in the recovery of superconductivity in underdoped YBa2Cu3O6+y (YBCO), we have performed polarized multiple-edge x-ray-absorption fine structure (XAFS) measurem
The Hartree-Fock paradigm of bilayer quantum Hall states with finite tunneling at filling factor nu=1 has full pseudospin ferromagnetic order with all the electrons in the lowest symmetric Landau l
We report inelastic light scattering measurements of dispersive spin and charge density excitations in dilute 2D electron systems reaching densities less than 10 sup (10) cm sup (-2).
Experiments on small superconducting tunnel junctions in a Giaever-Zeller-plus-SQUID geometry clearly show an I(V) feature due to Josephson supercurrent in a regime where single-electron charging e
We have determined the dephasing time for the 2D electron gas on the surface of H sub 2 crystal from low-field magnetoresistance measurements.
We observed unexpectedly narrow peaks (~1-2 meV) in the resonant enhancement of inelastic light scattering by the two dimensional electron gas.
We have measured the ultrafast simultaneous cross-gain and laser mode dynamics in a gain-clamped semiconductor amplifier perturbed by an intense detuned 150 fs pump pulse.
