Synopses of the Lectures

1. Classical vs Quantum Mechanics, Transformation Function (2 hours)
2. Feynman Path Integral Formula (2 hours)
3. Examples (free particle, harmonic oscillator, Aharonov-Bohm effect, etc.) (2 hours)
4. Semiclassical approximation (2 hours)

This lecture is to introduce recent results on observational cosmology to junior/senior students in physics.

1. Formation and Evolution of Galaxies (2hours)
   

   to cover from stars to galaxies.

2. Large Scale Structure and Dynamics of the Universe (2 hours)

   to cover extragalactic distance scale, large scale structure, cosmological parameters, new standard model, the accelerating universe.

The aim of this theoretical review is to help understanding the current expansion of universe from the most elementary viewpoint. I will introduce underlying assumptions, and "derive" the evolution equations using a simple toy model. Newtonian dynamics will be used to motivate the equation.

Solutions to the equation tells us how our universe have been evolving, and are categorized into three possible types. The simplest consequence of this exercise is a prediction for the age of the universe, which we discuss in some detail. Finally we motivate a new ingredient in standard cosmology, namely cosmological constant. We discuss how its introduction changes the evolution and why it became necessary.

Magnetism: Physics and Applications I
By Prof. Doochul Kim (SNU)

1. Magnetic Susceptibility, Localized Moments and Paramagnetism
2. Exchange Interactions, Heisenberg and other models and Magnetic Orderings
3. Spin Waves, Magnetic Phase Transitions and Critical Phenomena

In this lecture, as a follow-up of the previous one by Prof. Doochul Kim, I will give a brief introduction to a quantum mechanical view on magnetism in real materials, especially, consisting of transition metal elements and their compounds, and the physical principles for the applications of magnetic materials as magnetic sensors and memory devices. Further, I will discuss the connection between magnetism and superconductivity in high T_c superconductors, for a example.

1. A quantum mechanical view of magnets: Pauli exclusion principle and Coulomb interactions
2. Ferromagnetic and antiferromagnetic exchange interactions
3. Giant magnetoresistance (GMR) and magnetic sensors
4. MRAM (magnetic random access memory)
5. Magnetism and superconductivity: High T_c superconductivity
