quantax.model.UnrestrictedDet

class quantax.model.UnrestrictedDet

Unrestricted determinant wavefunction \(\psi(n) = \mathrm{det}(n_\uparrow \star U_\uparrow) \mathrm{det}(n_\downarrow \star U_\downarrow)\). Only works for spinful systems with specified number of spin-up and spin-down particles

__init__(U: Tuple[Array, Array] | None = None, dtype: dtype | None = None, out_dtype: dtype | None = None)

property U_full: Array

Returns the full orbital matrix U.
