1. Course Description

During the past decays, applied physics has pushed, inspired, and produced major high-tech industries from computing, communication, memory, display, transportation, to energy. Applied physics has played a drastically different role than the conventional paths taken by academic science and traditional industries. Quantum phenomena (and the related theories), new materials/atomic-scale thin films (and their fabrication tools such as molecular beam epitaxy, atomic layer deposition, metal-organic chemical vapor deposition), novel/high-performance devices, and atomic-scale probing tools have been intertwined and generated useful and essential products beneficial to human being, in revolutionizing computing/communication, and even drastically improving medical diagnosis.
Importantly, new physics/application has been discovered, such as transistors, lasers, quantum Hall effect, fiber optics, charge-coupled devices, 2-dimensional quantum materials. Indeed, applied physics has been strongly engaging in materials science, electrical/electronic devices, and high-tech industries.
Therefore, we have designed this new course of advanced applied physics topics related to spin and magnetism in quantum materials in the Spring Semester 2021.

2. Prerequisites

General physics and/or Electromagnetics at the undergraduate level.

Explanation of course format:

The course will consist of lectures discussion and group activities. We will spend 12 weeks in rigorously studying fundamentals of solid-state physics with Blundell “Magnetism in Condensed Matter” (Oxford Master Series) as the textbook, and with Dresselhause “Solid State Properties from bulk to Nano” (Springer) as the textbook.
Topics in Applied Physics strives to provide its readership with a diverse and interdisciplinary collection of some of the most current topics across advancing the quantum frontier, including:

Advanced Materials for spin-based qubits

2D layered crystals/Band structure engineering of 2D materials

Topological insulators/semimetals

Spin torque materials/Magnetic skyrmions

We then spend 4 weeks in researching in the ultimate quantum materials in spintronics and quantum computing. Perspective students (Ph.D., Master) will be assigned topics
for their final reports; the degree/level of the assigned research topics will depend on the perspective students’backgrounds. The reports will be presented in oral. The final-term orals will be given in 15 minutes.
The reports are not collections of information, but are required to be based on rigorous scientific knowledge. They are encouraged to broaden their knowledge in physics to tackle the challenges in the assigned/selected topics. Homework will be given from time to time.

4. Course Objectives

Objectives is to achieve a good understanding of basic concepts of spin related phenomena in new quantum materials and to apply these concepts to their own research projects. Students will acquire skills in theory, scientific method and discussion.
