what are the applications of computational physics?

Question

EXPLAIN.

Answer 1

The recent and rapid developments in science and engineering have been driven by a dramatic increase in the power and use of computers. Yet too many science and engineering graduates do not have strong enough backgrounds in computation to take advantage of these recent developments, while many computer science graduates do not have the background in mathematics and science needed for technical fields. With a Bachelor’s degree in Computational Physics, you could be bound for a career in:
•high-performance and scientific computing, in the energy and aerospace sectors, with chemical and pharmaceutical companies, with environmental management;
•research in an academic, industrial, or national laboratory;
•Teaching.

Answer 2

Many of the problems we woulde like to solve are to complicated to do by hand. The differential geomentry of general relativity and all of the crazy calculations of quantum physics provide such problems all the time. We can't even solve a system of three bodies for their respecive gravitational effects on each other over a period of time. What we can do is use computers to approximate the system. We can get some very close approximations in this manner.

Answer 3

Computational methods are widely used in solid state physics, fluid mechanics, and lattice field theory/lattice gauge theory (especially lattice quantum chromodynamics), among other areas. Computational solid state physics, for example, uses density functional theory to calculate properties of solids, a method similar to that used by chemists to study molecules. In solid state physics, the electronic band structure, magnetic properties and charge densities can be calculated by several methods, including the Luttinger-Kohn k.p method and ab-initio methods.
