<p>Dear ALPS users,</p>
<p><br>
</p>
<p>When I follow the ALPS TEBD tutorial about hard-core boson model(<a href="http://alps.comp-phys.org/mediawiki/index.php/ALPS_2_Tutorials:TEBD-01_bhquench" class="OWAAutoLink" id="LPlnk305156" previewremoved="true">http://alps.comp-phys.org/mediawiki/index.php/ALPS_2_Tutorials:TEBD-01_bhquench</a>)
by Python, I measured the average particle number for each site, i.e. 'Avg Number' except the
<span style="font-size: 12pt;">'Loschmidt Echo' and 'V' by the following python code:</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p>data = pyalps.load.loadTimeEvolution(pyalps.getResultFiles(prefix='1D_HardcoreBosonModel'), measurements=['Loschmidt Echo', 'V', 'Avg Number'])<span style="font-size: 12pt;"><br>
</span></p>
<p><br>
</p>
<p>Then I found the <span style="font-size: 12pt;">'Avg Number' equals 0.3! This means that the total particle number is 0.3*10=3, not 5. In the tutorial, the conserved quantum number is 'N_total': 5. When I change the 'N_total' to 1 and 10, I got the same
'Avg Number'=0.3</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p>Can any one give me some help? Thanks a lot!</p>
<p><br>
</p>
<p>Best regards,</p>
