J1-J2-model in Alps - Comp-phys-alps-users

27 Jul 2020


      Dear Alps users
I am trying to do a QMC simulation of the J1-J2-model on the s=1
rectangular lattice using the "dirloop_sse" app. I am fairly new to using
Alps, so I was wondering if someone would verify that my input parameters
are correct. My parameter files contains:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="ALPS.xsl"?>
<SIMULATION xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://xml.comp-phys.org/2003/8/QMCXML.xsd">
  <PARAMETERS>
<PARAMETER name="local_S">1</PARAMETER>
<PARAMETER name="L">20</PARAMETER>
<PARAMETER name="SWEEPS">10000</PARAMETER>
<PARAMETER name="LATTICE">anisotropic square lattice</PARAMETER>
<PARAMETER name="SEED">1261183832</PARAMETER>
<PARAMETER name="T">2</PARAMETER>
<PARAMETER name="W">6</PARAMETER>
<PARAMETER name="MODEL">spin</PARAMETER>
<PARAMETER name="a">1</PARAMETER>
<PARAMETER name="b">1.7446285117511835</PARAMETER>
<PARAMETER name="THERMALIZATION">100000</PARAMETER>
<PARAMETER name="J0">1</PARAMETER>
<PARAMETER name="J1">0.25</PARAMETER>
<PARAMETER name="h">0</PARAMETER>
  </PARAMETERS>
</SIMULATION>
Kind regards,
