Michele Dolfi, I am currently using DMRG. Are there any differences between mps_optim, sparsediag and dmrg for measuring String Order Parameters?

Very appreciate your helpful responce, Michele. mps did work. -----Original Messages----- From:"Michele Dolfi" <dolfim@phys.ethz.ch> Sent Time:2016-06-13 20:15:47 (Monday) To: comp-phys-alps-users@lists.phys.ethz.ch Cc: Subject: Re: [ALPS-users] String order parameters measurements Yes. From what I know, I think the mps_optim is the only application supporting “many-body operators". Something similar has already been discussed last year on the mailing list. Now you find an example in the tutorials folder in the repository: https://alps.comp-phys.org/svn/alps1/trunk/alps/tutorials/mps-example-01-str...
