A short introduction of the research activities present at the University of Seoul.

Condensed Matter

Condensed matter physics is a branch of physics that deals with the physical properties of condensed phases of matter, where particles adhere to each other. Condensed matter physicists seek to understand the behavior of these phases by using physical laws. In particular, they include the laws of quantum mechanics, electromagnetism and statistical mechanics.

Nanophysics

Nanoscience and nanotechnology are all about relating and exploiting phenomena for materials having one, two or three dimensions reduced to the nanoscale.

Particle and Fields

Particle physics or high energy physics or subatomic physics is the study the most fundamental particles and their interactions with the forces (strong, weak and electromagnetic). We are involved in the CMS experiment at CERN. Particle_and_Fields| Click here for more information.

Smart Film Lab

Smart film, also called Switchable film, is a product that is capable of adjusting light transmission between transparent and opaque using AC power. Due to moisture sensitivity, earlier versions of the film were used only to make smart glass by lamination on glass. With continual improvement in moisture resistance, the new (3rd) generation of the film can be directly installed on existing windows with special glue or self-adhesive. It combines many functions, such as light adjustment, UV and infrared blocking, advertising and security.

Statistical Physics

Statistical physics is a branch of physics that uses methods of probability theory and statistics, and particularly the mathematical tools for dealing with large populations and approximations, in solving physical problems. It can describe a wide variety of fields with an inherently stochastic nature. Its applications include many problems in the fields of physics, biology, chemistry, neurology, and even some social sciences, such as sociology. Its main purpose is to clarify the properties of matter in aggregate, in terms of physical laws governing atomic motion.

Terahertz Biophotonics

Most of the biomolecules, including proteins, RNA, and DNA have vibrational or torsional modes and hydrogen bonding mode corresponding to collective molecular oscillations, the relative motion of molecular secondary structure, and, specifically in DNA molecules, twisting and deformation of the double helix structure with frequencies in the 0.1 THz – 5 THz range. Moreover, terahertz wave has measured water molecules with a high sensitivity. Therefore, terahertz radiation can be used to study in terms of a physical and biological phenomenon for them. We focus on the invention of new techniques and applications for medical imaging in biophotonics.
