'Nonlocal' in the worm QMC
by 郭怀明 13 Jan '19

13 Jan '19

Dear all, I have a problem related to the worm QMC. I find there is a parameter 'nonlocal', which is set to 0 in the examples. I wonder what is the meaning of the parameter. Is it a systematic parameter for the method? Thank you for your reply. Sincerely, Huaiming Guo Beihang Unviersity

Exact diagnalization
by 郭怀明 27 Dec '18

27 Dec '18

Dear all, I use the exact diagonalization in ALPS to perform a calculation. I aim to know the distribution of several low-energy state. So I use the following statements: 'CONSERVED_QUANTUMNUMBERS' : 'N', 'N_total' :4, 'MEASURE_LOCAL[Local Density]':'n', 'NUMBER_EIGENVALUES' :1, My model is a hardcore Bose-Hubbard one. However the output file only gives the eigenvalues in the momentum sector. I wonder why "measure_local" does not work. I appriciate your reply. Sincerely, Huaiming Guo Beihang University

mpich option for alps
by Tadeusz Wasiutyński 21 Dec '18

21 Dec '18

I tried to compile alps-2.3.0 from source with mpi option. From my *cmake* (and *ccmake* as well) output it looks that compilers and libraries are properly recognized. Make and make test goes smoothly. However when it comes to execution there is error: *mpirun -np 12 spinmc --mpi parm7a.in.xml --Tmin 5This program has not been compiled for use with MPIThis program has not been compiled for use with MPI* Is this my mistake in compilation or there is something inside alps that I missed? My system is Centos7 and python 2.7.5 more details in attached files. Regards Tadeusz -- Tadeusz Wasiutyński

After well behaved cmake (output attached) I have smoothly compiled alps-2.3.0, python 2.7 and mpich with all tests passed OK. Unfortunately when job submitted it failed with note: *mpirun -np 12 spinmc --mpi parm7a.in.xml --Tmin 5This program has not been compiled for use with MPI* Where is the problem? -- Tadeusz Wasiutyński

entanglement spectrum of non-real Hamiltonian
by hamid mosadegh 01 Dec '18

01 Dec '18

Dear colleagues We compute entanglement spectrum of Hubbard model with real terms using ALPS easily. When an imaginary term as follow <BONDOPERATOR name="DSO_coupling" source="x" target="y"> I*cdag_up(x)*c_up(y)-I*cdag_down(x)*c_down(y)-I*cdag_up(y)*c_up(x)+I*cdag_down(y)*c_down(x) </BONDOPERATOR> is added to Hamiltonian, the entanglement spectrum is very sensitive to the size of lattice and MAXSTATES. Can ALPS compute the entanglement spectrum of any Hermitian Hamiltonian with non-real terms? Thanks for your attention -- H. Mosadeq Shahr-e-Kord University (SKU), Shahr-e-Kord , Iran

Re: [ALPS-users] compile error alps-2.3.0

Dear Benoit, I do not see a 2.2.b5 in official alps webpage. In fact I did compile without errors on Centos 7 version 2.3.0 with openmpi but when submitted run got the message: it is not compiled with mpi. I thought it might be due to some out dated software and tried another station with archlinux. When compiled under python2.7 gives different error than under python3.7 what makes me even more frustrated.

Re: [ALPS-users] parameter t' does not seem to work
by yulian chen 24 Oct '18

Sorry,the formatting on the page is out of order, so I send the email again. Dear Rongyang, Thank you for your help and sugggestions. I will pay attention to the details when I use ALPS and try to use ALPS MPS library to do DMRG simulation. Though the parameter works, I still have problems. i) The ground state energy is E0= -11.1895. But I have checked it by matlab and quspin using ED method, the results calculated by the two softwares are the same E0=-10.0499. Then I asked my friend to calculate the same model with the same parameters by itensor and he also got E0=-10.0499. I suspect that there is still a problem exist in my XML files. ii) I try to use ALPS MPS. And I will read the paper about ALPS MPS for more details later.When I use open chain lattice, it can run. But when I use 2 band sublattice open chain lattice, it shows --------------------------------------------------- Running task 1. This binary contains symmetries: nu1 MAQUIS repo r4143 Temporary storage is disabled Restoring state. Will start again at site -1 in sweep 30 MPS initialization has finished... Measurements. Measuring n Energy: 1 This task took 0.313551 seconds. Finished with everything. ------------------------------------------------ Why? iii) I want to write the tunneling rate t as a function of the position. -------------------------------------------------- import pyalps import numpy as np parms = [ { #'LATTICE' : "2 band sublattice open chain lattice", 'LATTICE' : "open chain lattice", 'LATTICE_LIBRARY': './lattices.xml', 'MODEL' : "sublattice boson Hubbard", 'MODEL_LIBRARY': './models.xml', 'CONSERVED_QUANTUMNUMBERS' : 'N', 'T' : 0, 't0' : 3-2*np.cos(x*np.pi+np.pi), #'t1' : 1, 'SWEEPS' : 30, 'MAXSTATES' : 300, 'init_state' : "thin" , 'NUMBER_EIGENVALUES' : 1, 'L' : 4, 'Nmax' : 1, 'N_total' : 2, 'MEASURE_LOCAL[n]' : 'n' } ] input_file = pyalps.writeInputFiles('ssh',parms) res = pyalps.runApplication('mps_optim',input_file,writexml=True) ------------------------------- Then I got the error: --------------------------------------------------- Traceback (most recent call last): File "./ssh.py", line 12, in <module> 't0' : 3-2*np.cos(x*np.pi+np.pi), NameError: name 'x' is not defined -------------------------------------------------- So how can I define the parameter when it is changed by site position?
