How can I construct a canonical infinite-temperature state with fixed total number of fermions ?
Posted: 01 Dec 2023, 13:12
Hello, everyone.
I'm working on the spinful Fermi-Hubbard model. I'd like to construct an infinite-temperature state where number of fermions equals to the lattice sites L (so-called half-filling). The number of spin-up and spin-down fermions are flexible with the total number of fermions conserved. I've found the module "PurificationMPS.from_infiniteT_canonical" but I don't know how to set the charge_sector specifically. Could anyone give an specific example to code that? Thanks a lot.
Best,
Amadeus.
