Confinement of fractional quantum number particles in a condensed matter system
B. Lake, A. M. Tsvelik, S. Notbohm +6
The idea of confinement states that in certain systems constituent particles can be discerned only indirectly being bound by an interaction whose strength increases with increasing…
Magnetic heat conductivity in : linear temperature dependence
C. Hess, H. ElHaes, A. Waske +5
We present experimental results for the thermal conductivity of the pseudo 2-leg ladder material . The strong buckling of the ladder rungs renders this material…
X-ray absorption spectroscopy on layered cobaltates Na_xCoO_2
T. Kroll, M. Knupfer, J. Geck +7
Measurements of polarization and temperature dependent soft x-ray absorption have been performed on Na_xCoO_2 single crystals with x=0.4 and x=0.6. They show a deviation of the loc…
Optical study of orbital excitations in transition-metal oxides
R. Rückamp, E. Benckiser, M. W. Haverkort +13
The orbital excitations of a series of transition-metal compounds are studied by means of optical spectroscopy. Our aim was to identify signatures of collective orbital excitations…
