Quantum Monte Carlo for Ising in transverse field
by zhian asadzadeh 25 Jul '11

25 Jul '11

Dear Matthias, by \Sigma_{i,j}, I mean \sum_{i,j}, for the exact result, we know the model is integrable, so by fermionization and finally diagonalizing the Hamiltonian we will end up to an Hamiltonian with sum over independent modes, H=\sum_{k} E(k) (2 a_{k}^{dagger} a_{k}-1) for the T=0 ground state energy, I have compared with DMRG results which are exactly same, so I am sure up to this point the form of E(k) and my summation over k space is correct. so finally for E(T) simply we have: E(T)=\sum_{k} E(k)(2*n(k,T)-1) in which n(k,T)=1/(exp(E(k)/T)+1) ::with Boltzmann constant=1 Regards, Zhian.

Quantum Monte Carlo for Ising in transverse field

Dear Matthias, my intention is doing finite T QMC for 2D ising in transverse field with the following Hamiltonian: H=-J \Sigma_{i,j} S_{i}^{z} S_{j}^{z}-h \Sigma_{i} S_{i}^{x} but for checking the accuracy of the numeric I did some checks for 1D case which we can have an exact results, probably I am expecting too much accuracy, for example: L=100, T=0.32859 Exact:: E(T)=-105.29789708270407, Mx(T)=0.27030367598168420 looper:: E(T)=-105.61795 (0.00554), M(T)=0.4093185 (0.000138) ( I think it is in z direction) with SWEEPS:6000000, THERMALIZATION=2000000 I have checked also for other sizes and very large SWEEPS. I don't expect to get exact result but I need much more accuracy in the calculated energy. and also other question: that magnetization which looper calculates is in the z direction? can I also measure M_{x} just with declaring it in parm file? Thanks a lot, Zhian.

restarting Lanczos iteration
by jessica.alfonsi＠unipd.it 22 Jul '11

22 Jul '11

Hi all, I'd like to modify the Lanczos *.cpp examples in IETL example folder to be able to restart the iteration from any interruption point during the Lanczos iteration. I suppose first one has to dump some information, for instance the cofficients of T-matrix and the starting vector, however the more difficult part would be the resuming of the iteration. Can somebody give me some hints on how accomplishing this task? Thanks in advance... Best regards, Jessica Alfonsi

Quantum Monte Carlo for Ising in transvers field

Dear All, I am trying to do QMC at finite temperature for calculating the magnetization of *Ising model in transverse field*, but I realized just looper code is working for this model, ( the others codes doesn't work with off diagonal matrix elements) but the result are not so good. I am interested to modify dirloop_sse for this model, is it possible? I appreciate your help, Thanks, zhian.

Re: [ALPS-users] tebd will not be built (Matthias Troyer)
by Cristian Degli Esposti Boschi 03 Jun '11

03 Jun '11

> Did you specify a Fortran-90 compiler? I guess so, at least I installed gfortran (4.4) via the Debian procedure. However, now I am worried about these two things: 1) (from the installation guidelines on the ALPS website) The tebd code requires a fortran compiler and that HDF5 be built with the --enable-fortran configure option. Will this be the case with Debian's gfortran? How to check a posteriori in HDF5 in my machine has been built with the --enable-fortran option? 2) what is the role of the two scripts $ $HOME/src/alps2/script/cmake.sh $HOME/opt $HOME/tmp $ $HOME/src/alps2/script/hdf5.sh $HOME/opt $HOME/tmp if all the dependent libraries are already ok, are these scripts necessary?

Define two-site spin correlation and controll the output in DMRG simulation
by 潘丽华 02 Jun '11

02 Jun '11

Dear ALPS users and developers, I am now studying the properties of the frustated Heisenberg spin chain. And the correlation functions is considered. The calculation result give (N+1)^2 terms of the two-sites' correlation value. Maybe we are interested in the result about C(l)=<Sz(N+2-l/2)Sz(N/2+l/2)>. I'd like to ask for your help. Can we modify the file /ALPS/alps-application/dmrg/dmrg/dmrg.c to get just the <Sz(N+2-l/2)Sz(N/2+l/2)> result? Or if there is another way to do so? The main reason we do not like the available one is that we find hat the output data of a single program is huge. So I'd like to consult you that if there's some other method to reduce the output data of the program? Thank you in advance for your time and effort to response. Best Regards! Your Sincerely, Pan Lihua

Hi shuai cui, your model is correct, and the result for the second run is fair but not so near to exact result, I suggest you increase the number of *maxstates (=300) *, and also your *lattice size*, you will get a better result, just for check point I give you the exact energy (per site) at h=1 (which is critical h in this model) J=-1, h=1 L=100, *E0=-1.2732919* ( This is exact energy not DMRG result) Zhian.
