arpes.simulation.SpectralFunctionMFL

class arpes.simulation.SpectralFunctionMFL(k=None, omega=None, temperature=None, a=10.0, b=1.0)

Implements the Marginal Fermi Liquid spectral function, more or less.

__init__(k=None, omega=None, temperature=None, a=10.0, b=1.0)

Initializes from parameters.

Parameters

• k – The momentum axis.

• omega – The energy axis.

• temperature – The temperature to use for the calculation. Defaults to None.

• a – The MFL a parameter. Defaults to 10.0.

• b – The MFL b parameter. Defaults to 1.0.
