quantax.model.MultiPf

class quantax.model.MultiPf

Multi-Pfaffian wavefunction \(\psi(n) = \sum_i \mathrm{pf}(n \star F_i \star n)\).

__init__(npfs: int = 4, F: Array | None = None, dtype: dtype | None = None, out_dtype: dtype | None = None)

Initialize the MultiPf model.

Parameters:

• npfs – The number of Pfaffians.

• F – The antisymmetric matrices with shape (npfs, Nfmodes, Nfmodes). If None, it will be initialized as paired Fermi sea orbitals.

• dtype – The data type for orbital parameters.

• out_dtype – The data type for computations and outputs. When dtype is real and out_dtype is complex, F stores the real and imaginary parts using real numbers.
