MpCanonical

The mp-canonical program constructs a maximal entangled state, suitable for calculations at finite temperature

 
Matrix Product Toolkit version HEAD-0.7.4.0 (subversion tree rev 824)
Compiled on Jan 16 2008 at 14:20:11
usage: mp-canonical <lattice> <quantum number> <outfile>

To work properly the lattice file has to support the structure needed for the construction of the state, i.e. a exact copy of the system with site index (i,aux). The mp-toolkit already contains a variety of models (e.g. spinchain-canonical-u1), where this is the case. Using such a model, the quantum numbers for the system and the ancillas have to be provided as a tuple x,y and are conserved seperately. This allows for canonical simulations, a grandcanonical version has yet to be added.
