### 3. Core Courses and Introduction

**Advanced Quantum Mechanics**

This course is designed for the first-year graduate students and senior undergraduate students who have finished an undergraduate quantum mechanics course. The goal of this course is to teach several important tools and techniques for practical applications of quantum mechanics, and prepare the students for further studies of quantum many-body theory.

The course introduces the Hilbert space and the operators, the observables and measurements, the uncertainty principle, the density matrix, identical particles, scattering theory, relativistic quantum mechanics, etc.

**Group Theory**

Group theory studies the algebraic structures known as groups. The concept of a group is central to abstract algebra. Various physical systems, such as crystals and the hydrogen atom, may be modeled by symmetry groups. Group theory and the closely related representation theory have many important applications in physics. The course focus on the applications in physics, especially in particle physics and condensed matter physics.

**Astrophysics Radiation Theory**

Astronomy is the oldest of all of the natural sciences, and its origins are bound up in ancient religious, mythological, and astrological practices. Astrophysics radiation theory is the definition of terms to be applied to astronomical radiation phenomena. In essence, it is the theory of the science of biological, chemical, physical, and logical laws with respect to any natural radiation source in the sky especially at night. Study astrophysics radiation theory may lead us to explore and understand the universe better.

**Quantum Statistics**

The Quantum statistics is an indispensable theoretical tool in modern condensed matter physics. The primary goal of the course is intended to be two-folded: one is to get used to the field-theoretical method of quantum many-particle systems and the other is to study macroscopic quantum phenomena such as the superconductivity and the super-fluidity by using the field theory.

Green's function approaches to quantum many-particle systems are introduced, where standard Feynman-Dyson perturbation theory in terms of diagrams are developed. The method is applied to several condensed matter systems, such as the electron-phonon systems, superconductors and super-fluid Helium. The electromagnetic and thermodynamic properties of conventional superconductors will also be studied.

**Computational Physics**

This course is designed for graduate or senior undergraduate students. It contains basics of computational physics and also introduces some currently used simulation techniques and some of the applications in the field of physics and material science. In order to make the course easy to digest and also to show some practical aspects of the materials introduced in the course, quite a few excises with different levels of difficulty are selected, which will certainly benefit students to fill in the gaps between physics and numerical physics. It will also benefit the students who are going to do research in computational science.

**Particle Physics**

Particle physic is the branch of physics that studies the nature of the particles that constitute matter and radiation.

Modern particle physics research focuses mainly on the subatomic particles, including atomic constituents such as the electrons, protons, and neutrons, and those produced by radioactive and scattering processes such as the photons, neutrinos and muons, as well as a wide range of exotic particles. The dynamics of the particle physics is also governed by the quantum field theory; they exhibit the wave–particle duality, displaying particle-like behavior under certain experimental conditions and wave-like behavior in others. Following the convention of particle physicists, the term elementary particles is applied to those particles that are, according to current understanding, presumed to be indivisible and not composed of other particles.

**Green's Functions**

The course is related to the course Quantum Statistics. Under many-body theory, Green's Function is used, specifically in quantum field theory, electrodynamics and statistical field theory, to refer to various types of correlation functions, even those that do not fit the mathematical definition. In quantum field theory, Green's functions take the roles of propagators which the course focuses on.
