The Hubbard chain at finite temperatures: ab initio calculations of Tomonaga-Luttinger liquid properties
G. Juttner, A. Klumper, J. Suzuki
We present a novel treatment of finite temperature properties of the one-dimensional Hubbard model. Our approach is based on a Trotter-Suzuki mapping utilizing Shastry's classical…
From Fusion Hierarchy to Excited State TBA
G. Juettner, A. Kluemper, J. Suzuki
Functional relations among the fusion hierarchy of quantum transfer matrices give a novel derivation of the TBA equations, namely without string hypothesis. This is demonstrated fo…
Reexamination of the microscopic couplings of the quasi one-dimensional antiferromagnet CuGeO_3
K. Fabricius, A. Klümper, U. Löw +2
Experimental data for the magnetic susceptibility and magnetostriction of CuGeO_3 are analyzed within a one-dimensional antiferromagnetic model with nearest ({J_1}) and next-neares…
Quantum phase transition in spin-3/2 systems on the hexagonal lattice - optimum ground state approach
H. Niggemann, A. Klümper, J. Zittartz
Optimum ground states are constructed in two dimensions by using so called vertex state models. These models are graphical generalizations of the well-known matrix product ground s…
