Effect of anisotropy on the field induced quantum critical properties of the three dimensional s=1/2 Heisenberg model
Effect of anisotropy field induced quantum critical properties
2010/11/18
The field induced quantum critical properties of the three dimensional spin-1/2 anisotropic antifer-romagnetic Heisenberg model has been studied. We have investigated the quantum phase transition betw...
Perturbative correction to the ground state properties of one-dimensional strongly interacting bosons in a harmonic trap
Perturbative correction ground state properties harmonic trap

We calculate the rst order perturbation correction to the ground state energy and chemical
potential of a harmonically trapped boson gas with contact interactions about the in nite repulsion Tonks-G...
