Re: [ALPS-users] Conserving up and down spins in TEBD

Hi Deepak, At present, the only way to fix the magnetization in the TEBD code for the Hubbard model is to add a magnetic field. Otherwise, the magnetization is set as you described. -Michael On Mon, Feb 10, 2014 at 2:44 PM, Deepak Iyer <deepak.g.iyer@gmail.com>wrote:

Hi

Is there any way to fix the no. of up and down spins in the TEBD code for the fermion hubbard model? It seems like I'm only allowed to conserve total N and the up and down are randomly assigned and varies from run to run.

Thanks! Deepak
