kaldo.phonons.Phonons.heat_capacity_2d

property Phonons.heat_capacity_2d

Calculate the generalized 2d heat capacity for each k point in k_points and each mode. If classical, it returns the Boltzmann constant in W/m/K.

Returns:

heat_capacity_2d – heat capacity in W/m/K for each k point and each modes couple.

Return type:

np.array(n_k_points, n_modes, n_modes)
