Urs, can you please send your input files, especially the lattice file. Could you please also check whether the dirloop_sse_v1 code, which is the old code, works on your input?

FQHE: using non-Hermitian operators as constrains for ED
by Zohar Ringel 28 Oct '10

28 Oct '10

Dear ALPS developers, Some background on the problem I have: --------------------------------------------------- I wish to use the exact diag. application for the FQHE effect on a thin-torus. This can be mapped to a 1D problem on a ring which has both total momenta (P) and total center-of-mass conservation (X). In a ring the position (j), is actually ill defined, therefore I need to define X as a non-Hermitian operator $X = \sum_j e^{i 2\pi j/L} \psi^{\dagger}_x \psi_x$ instead. My questions are: ---------------------- 1. Could a non-Hermitian operator such as X, be given as a conserved quantum number to the exact/sparse diagonalization applications ? 2. For a ring geometry and when within an tag: may I use the site's name ("j") as though it is a variable which holds an integer denoting the position (I need this for the last definition of X). Thanks in advance, Zohar.

Problem in ALPS 2.0b4 which does not occur in ALPS 1.3.3
by Urs Gerber ITP 25 Oct '10

25 Oct '10

**I am using ALPS 2.0b4 by simulating bilayer spin-1/2 Heisenberg model in an uniform magnetic field on the square lattice using dirloop_sse. It is strange that some runs are killed automatically without producing any output file. For example, for lattice size L = 12, the run with \beta = 24 goes smoothly to the end, but the run using \beta = 48 is killed. This also happens for other lattice sizes when beta gets too large. I will be grateful if anyone can help me with this. U.G.

Example of how to run ALPS applications from Maple
by Andriy Zhugayevych 25 Oct '10

25 Oct '10

On my web-page http://zhugayevych.me/maple/index.htm you will find a Maple worksheet example of sparse diagonalization in ALPS 2.0 for Windows. The direct links are: http://zhugayevych.me/maple/ALPS_example.mw (Maple worksheet only) and http://zhugayevych.me/maple/ALPS.zip (whole working folder). If you will find an easier or more efficient way to run ALPS applications from Maple, please, let me know. Best regards, Andriy Zhugayevych

ALPS 2 compilation on AIX

Dear Matthias, we've made again some progress with ALPS 2 b 3 compilation. Now it stops on test compilation with the following messages, it looks like a compiler bug similar to the previous one found for examples, so I'm going to turn off building tests, too. Is it OK ? Let me know please if you need the log files.

successful ALPS 2 beta 3 on AIX
by jessica.alfonsi＠unipd.it 21 Oct '10

21 Oct '10

Dear Matthias, I'd like to inform you that we've just had a successful installation of ALPS 2 beta 3 on AIX after turning off examples. At the moment the build of applications is turned off, since I needed a very basic configuration for compiling my code. We're going to try soon with build applications on and I'll let you know if there are any issues again. Then we'll try more recent revisions of ALPS. Thank you very much again for your support. Best regards Jessica
