## How to Earn a PhD in Mathematical Physics

Individuals who want to earn a PhD degree in mathematical physics will need to meet program admission requirements, such as holding a 3.0 GPA in all prior coursework, completing the GRE exam, submitting letters of recommendation, and writing a statement of purpose before they can start their academic journey. This program will typically take a minimum of four years to complete, and some of the courses that students can take over the course of their education include statistical mechanics, quantum mechanics, theoretical physics, and classical electrodynamics.

### Statistical Mechanics

A course in statistical mechanics will introduce students to a variety of classical theories present in physics and about the development of new theories in the field. Other topics that can be covered in this class include equilibrium statistics, kinetic theories as they relate to liquids, thermodynamics, and equilibrium mechanics. Additionally, this course may also teach students about the Boltzmann equations and how to properly use them.

### Quantum Mechanics

Quantum mechanics focuses on the topics of wave mechanics and the axioms of quantum mechanics. A class like this will introduce relativistic theory, and it may also cover a number of other areas like the hydrogen atom, the theory of angular momentum, and principles of matrix mechanics. Students can also get a better understanding of Schroedinger's wave mechanics and the Hilbert space methods.

### Mathematical Physics

Students in a mathematical physics class can learn about matrix algebra, complex variables, linear vector spaces, and group theory. This course will teach students about the problems that may arise in the field of mathematical physics, and how to handle them. Other areas that could be covered include integration methods and the unbound operators in Hilbert space.

### Classical Electrodynamics

Students are introduced to the field of advanced electromagnetostatistics and time-varying fields. Other topics that can be covered here include electrostatistics, conservation laws, radiation theory, and physical optics. By the conclusion of this course, students will be familiar with Maxwell's equation and Green's functions.

### Nuclear Physics

A course in nuclear physics can touch on current research being done in the field, in addition to covering hadronic physics and nuclear astrophysics. Students will learn about the processes of nuclear reactions and understand nuclear structures.
