You use ccmake to set the variable CMAKE_Fortran_FLAGS to -fopenmp

Hi, all
With kind help of Matthias, I finally compile all functions of ALPS2.1.1
and install it on my Ubuntu 10.02 Lucid. And in my system, it is python
2.6.5, and no VisTrails or ALPS vistrails extensions installed.

But I have got an extra problem:
When I am trying to run python file in tutorials via command line, it
always returns
---------------------------------error----------------------------------
Traceback (most recent call last):
  File "tutorial8a.py", line 28, in <module>
    import pyalps
ImportError: No module named pyalps
---------------------------------END----------------------------------

So, I run the test_py.py, all files in tutorials return the same error
mentioned above.(see attachment) Besides, before runing ALPS, I have
already added lines to /home/jiang/.bashrc as some users in ALPS-users
suggest

---------------------lines added to .bashrc-------------------
# ALPS
release_dir=/home/jiang/opt/alps (I am sure this is where I install the
ALPS)
export LD_LIBRARY_PATH=$release_dir/lib/
export PATH=$PATH:$release_dir/bin/
export PYTHONPATH=$release_dir/lib/
------------------------END-----------------------------------------

Any advice is welcome and helpful.

Please send the result of the following command: ls -lR $release_dir/lib/

Dear all,

I am trying to add the spin-orbit coupling term to the 1D Hubbard model. I
use the standard files
for 1D Hubbard model in the library and add those codes:
-----------------------------------------------------------------------------------
<BONDOPERATOR name="SOC" source="x" target="y">

cdag_up(y)*c_down(x)-cdag_down(y)*c_up(x)+cdag_down(y)*c_up(x)-cdag_up(y)*c_down(x)
</BONDOPERATOR>
-----------------------------------------------------------------------------------
and
-----------------------------------------------------------------------------------
  <BONDTERM source="i" target="j">
    <PARAMETER name="t#" default="0"/>
    <PARAMETER name="alpha" default="0"/>
    -t*fermion_hop(i,j)-*alpha**SOC(i,j)
  </BONDTERM>
-----------------------------------------------------------------------------------
to the model XML file just like before. But it seems it does not work. The
results keep the same
when I change the parameter 'alpha' .

Can you give me some advices ? Thank you very much in advance.

With best wishes,
Ahai Chen

I think archlinux is a good choice. Arch is much more stable than ubuntu, at least in my opinion. And arch has the most powerful wiki than all of the other distribution. If you install yaourt, you could easily compile ALPS with the simple command: yaourt alps.

As usual, without full inputs and scripts nobody will be able to really tell you what is happening. My conjecture is that you have declared Sz as a conserved quantum number, and then this term actually never acts.
