非相対論的量子力学の復習後、相対論的な運動をする粒子に対する量子力学を構成する。特に電子が従うディラック方程式などについて深く考察する。前半ではディラック方程式を波動関数の方程式として考え、その成功と問題点を見る。後半では場の量子化の概念を導入し、場の量子論への入門的事項を学ぶ。
After reviewing the non-relativistic quantum mechanics, I will construct the quantum mechanics describing a particle with relativistic motion. A particular emphasis is given to the Dirac equation describing the motion of electrons. In the first half of the lectures, I describe the Dirac equation as an equation for wave functions,and see its success and failure. In the second half of the lectures,the notion of quantization of fields is explained as an introduction to quantum field theory.

To understand modern physics ranging from elementary particle physics to condensed matter physics and cosmology, the concept of quantum mechanics, which describes the law of Nature in the microscopic scale, is an indispensable ingredient. In this lecture we learn the basic concept of quantum mechanics continuing the lecture course of Quantum Mechanics I.
Electromagnetic phenomena are abundant in our daily lives from electricity (volts, amperes, watts, etc) we use every day, magnets on our refrigerator, to all lights surrounding us. The vastness and complexity of this interesting subject results from only four equations, Maxwell's equations. In this course, they shall be the starting and ending point. Our goal is to appreciate and understand various manifestations of these four equations by studying electric and magnetic forces and interactions between them.
現代物理学における重要な概念のひとつである対称性について、その数学的基礎である群論について学ぶ。ここでは、特に、量子力学を理解する上で強力な道具となりうる群の表現論を学ぶことで、対称性に立脚した物理の見方と量子系への応用力を身につける。線形代数などの数学と量子力学Iの内容を習得していることを前提とする。
Symmetry is one of the most essential concepts in modern physics. Here, we will study the mathematical basics of group theory. In particular, we will learn the representation theory of groups, which can be a powerful tool in understanding quantum mechanics and acquiring perspectives on physics and applications to quantum systems using group theory. We assume that the students have enough knowledge of linear algebra and the contents of Quantum Mechanics I.
This is a course introducing recent topics in various areas of science including quantum mechanics and quantum technology. Lectures are given by 13 faculty members from all the departments (Mathematics, Physics, Astronomy, Geophysics, Chemistry, and Earth Science) in Graduate School of Science. Each faculty member discusses up-to-date topics in his/her specialty. The lectures are prepared for non-experts and thus this course is an outstanding opportunity to obtain familiarity with areas other than the students' specialties. The class meets every Wednesday, 4:20-5:50 pm.

本講義では磁性を中心とした固体中の電子相関に関する基本的な事項について、局在・遍歴の両視点から解説する。具体的な物質群としてd電子系、f電子系を取り上げるが、あえてd電子系を局在の立場から、f電子系を遍歴の立場から眺めることで、これら強相関電子系の理解を深める。
This course provides a basic understanding of electron correlation in solids, focusing on magnetism. The lecture explains the subject from both localized and itinerant perspectives. Specific material groups such as d-electron and f-electron systems are discussed, with d-electron systems viewed from a localized perspective and f-electron systems from an itinerant perspective. This approach enhances the understanding of these strongly correlated electron systems.
