The Half-Filled One-Dimensional Extended Hubbard Model: Phase diagram and Thermodynamics
S. Glocke, A. Klümper, J. Sirker
We study the thermodynamics of the one-dimensional extended Hubbard model at half-filling using a density-matrix renormalization group method applied to transfer matrices. We show…
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…
The density-matrix renormalization group applied to transfer matrices: Static and dynamical properties of one-dimensional quantum systems at finite temperature
S. Glocke, A. Klümper, J. Sirker
The density-matrix renormalization group (DMRG) applied to transfer matrices allows it to calculate static as well as dynamical properties of one-dimensional quantum systems at fin…
S=1/2 antiferromagnetic Heisenberg chain with staggered fields: Copper pyrimidine and copper benzoate using the density matrix renormalization group for transfer matrices
S. Glocke, A. Klümper, H. Rakoto +3
We consider the spin-1/2 antiferromagnetic Heisenberg chain in a staggered magnetic field describing materials such as copper benzoate and copper pyrimidine dinitrate. Using the de…
