Hi, everyone. I'm working on calculating the infinite temperature correlation function \langle \hat{S}_i^z(t) \hat{S}_0^z\rangle_{\beta=0} . The point is to evolve two states \lvert\psi\rangle and \hat{S}_0^z\lvert\psi\rangle and calculate the expectation value of \hat{S}_i^z . The infinite temperat...

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....
