One-dimensional phase transitions in a two-dimensional optical lattice
Magnus Rehn, Sara Bergkvist, Anders Rosengren +4
A phase transition for bosonic atoms in a two-dimensional anisotropic optical lattice is considered. If the tunnelling rates in two directions are different, the system can undergo…
Localized spin ordering in Kondo lattice models
I. P. McCulloch, A. Juozapavicius, A. Rosengren +1
Using a non-Abelian density matrix renormalization group method we determine the phase diagram of the Kondo lattice model in one dimension, by directly measuring the magnetization…
Quantum Ising model in a transverse random field: A density-matrix renormalization group analysis
A. Juozapavicius, S. Caprara, A. Rosengren
The spin-1/2 quantum Ising chain in a transverse random magnetic field is studied by means of the density-matrix renormalization group. The system evolves from an ordered to a para…
