Effects of Two Energy Scales in Weakly Dimerized Antiferromagnetic Quantum Spin Chains

A. Brühl, B. Wolf, V. Pashchenko +9

By means of thermal expansion and specific heat measurements on the high-pressure phase of (VO)PO, the effects of two energy scales of the weakly dimerized antiferromag…

Density matrices for finite segments of Heisenberg chains of arbitrary length

Jens Damerau, Frank Göhmann, Nils P. Hasenclever +1

We derive a multiple integral representing the ground state density matrix of a segment of length of the XXZ spin chain on lattice sites, which depends on only parametr…
