Hello, I create my own model in the model.xml file. It works when the MAXSTATES=60, but when I set MAXSTATES=100, the program is interrupted by showing a message "vector::_M_fill_insert". There is no output file and here are all the files I have. Thank you for your reply. Thank you. Best wishes Tianyou

Problems downloading libraries
by Niraj Ghimire 27 Mar '14

27 Mar '14

Dear alps users, I have been trying to build alps package from source on Windows 7 OS. I have been following the outdated instructions on the page https://alps.comp-phys.org/trac/wiki/AlpsOnWindows. I could not find the proper versions of Zlib, SZlib, Lpsolve and SQlite. There are links on this webpage that read "Check out the source code from <>" where <> is, for instance, https://alps.comp-phys.org/svn/alps1/trunk/wistaria/windows/lpsolve for "Lpsolve". I don't know how to download the source codes using these links. I tried to download the source codes from a trusted webpage like sourceforge.net, some of them work while others don't and I keep getting errors. Please help me.

Nearest-neighbor interaction
by Tianyou YI 25 Mar '14

25 Mar '14

Hello, I need to create my own Hamiltonian. I have a term of nearest-neighbor interaction, and I write in the model file </BONDTERM> <BONDTERM source="i" target="j"> -t*bdag(i)*b(j) </BONDTERM> Here in the field of the target should I write target="i+1" or should I write simply target="j". What is the difference between the two cases ? In the second case, the source i will go through all the sites and the target j will go through alll the sites too, I have then interaction of next-nearest-neighbor terms and so on ? Thank you for your reply. Best wishes Tianyou

Using DISORDERSEED in Bose glass worm simulations: Python script
by vvarma＠ictp.it 14 Mar '14

14 Mar '14

Dear ALPS users, I am trying to run a very simple worm simulation with disorder (site-dependent 'mu') for the Bose-Hubbard model using a Python script. If I simply translate a working parameter file (obtained from the ALPS website) into the below Python code, 'random()' is unrecognized (which is not so for the parameter file where the simulation goes through). But if I include 'import random' at the beginning of the Python script then the simulation does go through but a different model gets simulated (i.e. a random 'mu' but equal for all sites). I was wondering, should not the below Python script translated directly from a similar working parameter file run as is for the desired model? /*<SNIP>*/ import pyalps import matplotlib.pyplot as plt import pyalps.plot #prepare the input parameters parms = [] for DISORDERSEED in [34275, 49802, 82529]: parms.append( { 'LATTICE' : "inhomogeneous square lattice periodic", 'MODEL' : "boson Hubbard", 'T' : 0.1, 'L' : 4 , 't' : 1.0 , 'DISORDERSEED' : DISORDERSEED, 'mu' : 5.0*2*(random()-0.5), 'U' : 1.0 , 'NONLOCAL' : 0 , 'Nmax' : 2 , 'THERMALIZATION' : 100, 'SWEEPS' : 5000 } ) /*<SNIP>*/ Thanks, Vipin
