Phonon-assisted luminescence by finite atomic displacements

In recent years, several articles have been published with Yambo, who calculated the phonon-assisted luminescence by means of finite atomic displacements[1][2][3][4].
In this tutorial we will show how to use YamboPy in combination with Yambo to perform these kind of calculations. For a general review of finite displacements calculations of vibrational properties we recommend this article.[5].
