Decay and coherence of two-photon excited yellow ortho-excitons in Cu2O
K. Karpinska, M. Mostovoy, M. A. van der Vegte +2
Photoluminescence excitation spectroscopy has revealed a novel, highly efficient two-photon excitation method to produce a cold, uniformly distributed high density excitonic gas in…
Charge and sodium ordering in beta-Na_0.33V_2O_5
P. H. M. van Loosdrecht, C. N. Presura, M. Popinciuc +7
Polarized Raman and optical spectra for the quasi one-dimensional metallic vanadate beta-Na0.33V2O3 are reported for various temperatures. The spectra are discussed in the light of…
Charge kinks as Raman scatterers in quarter-filled ladders
E. Ya. Sherman, C. Ambrosch-Draxl, P. Lemmens +2
Charge kinks are considered as fundamental excitations in quarter-filled charge-ordered ladders. The strength of the coupling of the kinks to the three-dimensional lattice depends…
Quantum Spin Systems: From Spin Gaps to Pseudo Gaps
P. Lemmens, M. Fischer, M. Grove +5
Many low dimensional spin systems with a dimerized or ladder-like antiferromagnetic exchange coupling have a gapped excitation spectrum with magnetic bound states within the spin g…
Low Dimensional Correlated Systems: Cugeo_3 and Nav_2O_5
P. H. M. Van Loosdrecht, J. Zeman, G. Martinez +3
Some of the properties of the low-dimensional electronically correlated materials \cgo and \nvo are discussed. The emphasis lies on recent results obtained using Raman scattering a…
