Computational physics topics
Computational physics is the study and implementation of numerical analysis to solve problems in physics.
Historically, computational physics was the first application of modern computers in science, and is now a subset of computational science..

What do you like most about numerical methods in physics with Python?
'In Numerical Methods in Physics with Python by Gezerlis, one finds a resource that has been sorely missing! As the usage of Python has become widespread, it is too often the case that students take libraries, functions, and codes and apply them without a solid understanding of what is truly being done ‘under the hood’ and why
×Computational physics is an approach to physics that uses computers to solve problems where a precise theory exists but the resulting equations are intractable to traditional analytical approaches. The essential point in computational physics is not the use of machines, but the systematic application of numerical techniques and algorithms that approximate physical description of complicated systems. Some examples of computational methods used in physics include root finding, system of linear equations, ordinary differential equations, integration, and partial differential equations.
Computational chemical methods in solid-state physics follow the same approach as they do for molecules, but with two differences.
First, the translational symmetry of the solid has to be utilised, and second, it is possible to use completely delocalised basis functions such as plane waves as an alternative to the molecular atom-centered basis functions.
The electronic structure of a crystal is in general described by a band structure, which defines the energies of electron orbitals for each point in the Brillouin zone.
Ab initio and semi-empirical calculations yield orbital energies, therefore they can be applied to band structure calculations.
Since it is time-consuming to calculate the energy for a molecule, it is even more time-consuming to calculate them for the entire list of points in the Brillouin zone.
