Spin-Phonon Chains with Bond Coupling
Carsten Raas, Ute Löw, Götz S. Uhrig +1
We investigate the antiadiabatic limit of an antiferromagnetic S=1/2 Heisenberg chain coupled to Einstein phonons via a bond coupling. The flow equation method is used to decouple…

Thermodynamic Properties of the Dimerised and Frustrated S=1/2 Chain
Alexander Bühler, Ute Löw, Götz S. Uhrig
By high temperature series expansion, exact diagonalisation and temperature density-matrix renormalisation the magnetic susceptibility and the specific heat of dimeri…
