Dear All, I made a definition of the pyrochlore lattice (lattices.xml) and put it at a repository https://github.com/kadowaki-h/LatticesPyrochloreCubic. A simple example of calculating specific heat C(T, H=0) of the NN Spin Ice model is also given in the repository. Best wishes, Hiroaki Kadowaki Department of Physics, Tokyo Metropolitan University Hachioji-shi, Tokyo 192-0397, Japan kadowaki(a)tmu.ac.jp

mps_overlap
by 杨超 27 Mar '18

27 Mar '18

Dear AllI would like to use application 'mps_overlap' to calculate the overlap of two MPS wavefunctions with the checkpoint files MPS1.task.out.chkp and MPS2.task.out.chkp. However, I do not see any tutorial or document about how to use 'mps_overlap' with python. So how can I get the overlap of these wavefunctions?Best wishes!Yang Chao

Re: [ALPS-users] No output from DWA

By default, it is set false because it will slow down your simulation (very...) drastically. If you want them, please set in your params: MEASURE[Green Function] = 1 http://alps.comp-phys.org/mediawiki/index.php/Documentation:dwa <http://alps.comp-phys.org/mediawiki/index.php/Documentation:dwa> > > > >> On 23 Mar 2018, at 7:42 PM, Oskar Amadeusz Prośniak <oskar.krak(a)gmail.com <mailto:oskar.krak@gmail.com>> wrote: >> >> Hey, >> I am now working with revision 7650 where DWA works fine.

No output from DWA
by Oskar Amadeusz Prośniak 23 Mar '18

Dear all, I have just installed ALPS via conda and faced an unexpected problem with the tutorial dwa-01-bosons. While running the program tutorial1a.py on my laptop after thermalization is finished I get a segmentation fault. I changed the code a bit (see below) to run this tutorial on the bigger machine on which there is ALPS also installed via conda. The segmentation fault does not occur, however the program does not produce any output files and the produced graph is empty. I have also tried to run DWA with these parameters without python - using input file, but this have also ended with a segmentation fault. import pyalps bin_dir = '/net/people/plgprosniak/miniconda2/bin/' parms = [] for t in [0.01, 0.02, 0.03, 0.04, 0.05, 0.06, 0.07, 0.08, 0.09, 0.1]: parms.append( { 'LATTICE' : "square lattice", 'MODEL' : "boson Hubbard", 'T' : 0.1, 'L' : 4 , 't' : t , 'mu' : 0.5, 'U' : 1.0 , 'Nmax' : 2 , 'THERMALIZATION' : 100000, 'SWEEPS' : 2000000, 'SKIP' : 500, 'MEASURE[Winding Number]': 1 } ) input_file = pyalps.writeInputFiles('parm1a', parms) res = pyalps.runApplication(bin_dir+'dwa', input_file, Tmin=5, writexml=True) # Setting graphical output import matplotlib as mpl mpl.use('agg') # Evaluating the simulation and preparing plots using Python import pyalps import matplotlib.pyplot as plt import pyalps.plot as aplt results = pyalps.getResultFiles(prefix='parm1a') print(results) data = pyalps.loadMeasurements(results,'Stiffness') rhos = pyalps.collectXY(data,x='t',y='Stiffness') fig=plt.figure() aplt.plot(rhos) plt.xlabel('Hopping $t/U$') plt.ylabel('Superfluid density $\\rho _s$') fig.savefig('/net/scratch/people/plgprosniak/test/test_dwa.png') Best regards, Oskar A.

Run ALPS within Anaconda on Windows
by jiangzeyunj 05 Mar '18

Dear developers and users: I'm trying to run ALPS with anaconda on Win10. The installation "conda install -c conda-forge alps" has completed, and then I try to run an example "tutorials/intro-01-basics/tutorial-full.py". I load the corresponding python script into "spyder" IDE integrated in anaconda and then run it, but an error comes that : File "E:\Anaconda2\envs\Monte2\lib\site-packages\pyalps\tool.py", line 604, in collectXY if iset.props['observable'] != y and not y in iset.props: "AttributeError: 'list' object has no attribute 'props' ". So, can anyone tell me how to solve this problem? Thank you~ -- 姜泽禹清华大学物理系电话：17888836973 jiangzeyuNJ(a)163.com jzy14(a)mails.tsinghua.edu.cn
