The effect of sodium ordering on rattling modes in sodium cobaltate
NaxCoO2 has exceptional thermoelectric properties, including low thermal conductivity, and it is currently under consideration for use in power recovery applications and as a... -
Zero field splitting and quasiparticle breakdown in the two-dimensional quant...
In our recent NRSE experiment on the quasi two-dimensional quantum spin liquid PHCC at TRISP at FRM-II, we have found a zero field splitting (ZFS) of the magnon line of about 50... -
Magnetic Excitations of a Model Quantum Spin Ladder
(C5H12N)2CuBr4 is the best realisation found to date of an antiferromagnetic quantum spin ladder in the strong coupling limit. This system displays an extremely rich phase...
