One-dimensional extended Bose-Hubbard model with a confining potential: a DMRG analysis
Laura Urba, Emil Lundh, Anders Rosengren
The extended Bose-Hubbard model in a quadratic trap potential is studied using a finite-size density-matrix renormalization group method (DMRG). We compute the boson density profil…

Density matrix renormalization group analysis of the spin 1/2 XXZ chain in an XY symmetric random magnetic field
Laura Urba, Anders Rosengren
The spin 1/2 XXZ chain in a random magnetic field pointing in the Z direction is numerically studied using the Density Matrix Renormalization Group (DMRG) method. The phase diagram…
