Hello, In the tutorial on the alps web page line: import pyalps.pyplot should be rather: import pyalps.plot as it is in the files stored in distribution. Regards Tadeusz Wasiutynski

multi-site terms support in hamiltonian
by Oles Zaburannyi 02 May '11

02 May '11

Hello, I have question about multi-site terms support in hamiltonian definition. I found some mention about that in ALPS workshop (2006) In recent wiki announced that `Extensions to more complex terms, such as 3- and 4-site terms are in preparation and will be included here as soon as the ALPS libraries support such terms.` There is possibility to include now such terms? Will arise huge problems in DMRG methods after including such milti-site terms? Thanks, Oles

Simulation of O(N) models

Hi ALPS community, first of all sorry for my English and sorry if the questions that I'm going to make are trivial but I'm not a real expert in programming and using web libraries. I'm interested in doing classical MC simulations of O(N) models. I saw on the ALPS page Documentation:ClassicalMCSimulations and in particular ALPS application: spinmc that is possible to extend the application to additional O(N) models "...by editing the file mc/spins/spinmc_factory.C " I need to run a simulation for a O(4) model so I tried to edit the file spinmc_factory.C to this purpose in the following way /***************************************************************************** * * ALPS Project Applications * * Copyright (C) 2009 by Matthias Troyer <troyer(a)comp-phys.org>, * Synge Todo <wistaria(a)comp-phys.org> * * This software is part of the ALPS Applications, published under the ALPS * Application License; you can use, redistribute it and/or modify it under * the terms of the license, either version 1 or (at your option) any later * version. * * You should have received a copy of the ALPS Application License along with * the ALPS Applications; see the file LICENSE.txt.

evaluating simulation results in python in ALPS 2

Or, more to the point, how do I load the simulation results into python? Thanks in advance, Zhenya

boost_filesystem causes exception
by Andreas Herrmann 24 Apr '11

24 Apr '11

Dear Alps users, there is a bug in the boost library that is shipped with alps. On some systems, any program that is linked to boost_filesystem or alps aborts with the following error message. terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid Aborted This bug is known and a patch exists [1]. I tried the patch and it worked for me. Another quick workaround is setting LC_ALL="C". I'm currently using Ubuntu 10.10. The bug appears both in the deb-package and also when compiling from source. deb-version: alps 2.0.0-4, boost 1.45.0-1 source package: alps-2.0.0-r5363-src-with-boost Best regards, Andreas Herrmann [1] https://svn.boost.org/trac/boost/ticket/4688

QMC Worm Algorithm / Bose-Hubbard model
by Peter Schauß 24 Apr '11

24 Apr '11

Hello, the Bose-Hubbard QMC example runs nicely after i got all the installation stuff done. We are interested in the full single shot density distribution for a qmc simulation of small bose-hubbard-systems (<100sites). This would enable us to run the same evaluation code on the simulation which we use for our data. Is there a simple way to add this (or other observables like the parity projected density) to the observables which are written to the output files? Best regards, Peter Schauß -- Peter Schauß Max-Planck-Institut für Quantenoptik Hans-Kopfermann-Str. 1 D-85748 Garching Germany Tel: +49-(0)89-32905-294 peter.schauss(a)mpq.mpg.de
