Density Profiles in Random Quantum Spin Chains
F. Igloi, H. Rieger
We consider random transverse-field Ising spin chains and study the magnetization and the energy-density profiles by numerically exact calculations in rather large finite systems (…

Vortex lines in the three-dimensional XY model with random phase shifts
M. S. Li, T. Nattermann, H. Rieger +1
The stability of the ordered phase of the three-dimensional XY-model with random phase shifts is studied by considering the roughening of a single stretched vortex line due to the…

The One-Dimensional ANNNI model in a Transverse Field: Analytic and numerical study of Effective Hamiltonians
H. Rieger, G. Uimin
We consider a spin- chain with competing nearest and next-nearest neighbor interactions within a transverse magnetic field, which is known to be an equiavelent to the…
