[ALPS-users] QMC of Bose-Hubbard model with NNN interaction

23 Oct 2015

      Dear all,

I want to use QMC in ALPS to simulate Bose-Hubbard model with NNN
interaction, we know for NN interaction V, we can define V as following:
  <BONDTERM source="i" target="j">
    <PARAMETER name="V" default="0"/>
    V*n(i)*n(j)
  </BONDTERM>

Now I want to include NNN interaction, how can I define it? (source="i"
target="*?*")

Best regards,
Tao Ying
