# Quantum physics functions (plasmapy.formulary.quantum)¶

Functions for quantum parameters, including electron degenerate gases and warm dense matter.

## Functions¶

 deBroglie_wavelength(V, particle) Calculates the de Broglie wavelength. thermal_deBroglie_wavelength(T_e) Calculate the thermal deBroglie wavelength for electrons. Fermi_energy(n_e) Calculate the kinetic energy in a degenerate electron gas. Thomas_Fermi_length(n_e) Calculate the exponential scale length for charge screening for cold and dense plasmas. Wigner_Seitz_radius(n) Calculate the Wigner-Seitz radius, which approximates the inter- particle spacing. chemical_potential(n_e, T) Calculate the ideal chemical potential.
