Ising thin films with modulations and surface defects
W. Selke, M. Pleimling, I. Peschel +3
Properties of magnetic films are studied in the framework of Ising models. In particular, we discuss critical phenomena of ferromagnetic Ising films with straight lines of magnetic…
A Spin-1/2 Model for CsCuCl_3 in an External Magnetic Field
A. Honecker, M. Kaulke, K. D. Schotte
CsCuCl_3 is a ferromagnetically stacked triangular spin-1/2 antiferromagnet. We discuss models for its zero-temperature magnetization process. The models range from three antiferro…
Density-matrix spectra for integrable models
I. Peschel, M. Kaulke, Ö. Legeza
The spectra which occur in numerical density-matrix renormalization group (DMRG) calculations for quantum chains can be obtained analytically for integrable models via corner trans…
A DMRG study of the q-symmetric Heisenberg chain
M. Kaulke, I. Peschel
The spin one-half Heisenberg chain with symmetry is studied via density-matrix renormalization. Ground-state energy and -symmetric correlation functions are calcula…
