Plasma physics focuses on core researches on high temperature nuclear fusion energy and some applications regarding active particles at plasma state.
Accelerator physics research is conducted by constructing/ managing the 3rd and 4th generation accelerators in Pohang, and experimenting with electronic and protonic acceleration.

The military service exempted technical research personnel is a special program that is run by the government to encourage industrial development at a national scale by allowing students to
POSTECH is one of the research centers that runs the technical research personnel program designated by the government, and recruits research personnels based on the regional(Daegu, Kyeongbuk) quota. Many percentage of POSTECH students have succeeded in being in the quota, and almost every student at the physics department who applied have been selected at the research personnel. Research personnels are recruited based on English comprehension abilities, and the acquisition of a certificate on Korean history.

Although many constituents are quite busy working on their world-leading research, they also spare some time to hang out together. For example, many professors and students team up to win at the physics department annual futsal-league, with a winning prize of 500,000 won! Also, there is a “physicists’ night” every year, where every faculty and students gather to eat delicious meals together. All constituents of the department study and research under such cozy and encouraging environment.

All graduate students at the physics department are fully funded in terms of their tuition and living expenses.
The actual funding amount can differ laboratory by laboratory, or depending on how many external scholarships a student receives. However, all students receive at least 1,520,000 won (for a 2nd year student, 2019) based on the government BK 21+ funding. As this is the least amount, you have other possibilities of receiving more money from other types of funds (e.g. government, companies, etc.).

POSTECH has many state-of-the-art facilities such as the 3rd & 4th generation accelerators (PAL), the Max-Planck Institute (MPK), the Institute for Basic Science (IBS), SRC research center for topological matter, Asia-Pacific Center for Theoretical Physics (APCTP), Basic research center for quantum optics (BRL), Global research center for DNA recovery (GRL), and the National Institute for Nanomaterials Technology (NINT).
If you wish to major in experimental condensed matter physics, you can work at 3rd & 4th generation accelerators (PAL), the Max-Planck Institute (MPK), the Institute for Basic Science (IBS), SRC research center for topological matter.
If you wish to major in particle physics or theoretical condensed matter physics, you can work at the Institute for Basic Science CALDES (IBS CALDES), SRC research center for topological matter, Asia-Pacific Center for Theoretical Physics(APCTP).
If you wish to major in optics, you can work at the Max-Planck Institute (MPK), Basic research center for quantum optics (BRL), and the National Institute for Nanomaterials Technology (NINT).
If you wish to major in biophysics or complex systems, you can experiment at the Global research center for DNA recovery (GRL), or do theoretical research at the Asia-Pacific Center for Theoretical Physics (APCTP).
If you wish to major in plasma/ accelerator physics, you can cowork with the KSTAR research institute.

Research in particle physics involves studying various quantum gravity phenomena such as black holes using symmetries, and ideas from the string theory.

Biophysics is an interdisciplinary field that studies biological phenomena from molecular scale to macroscopic scale via the eyes of physics and mathematics.
Complex systems is a new rising field of statistical physics. It can serve as a novel comprehensive tool for other fields by extending the physical tools of the conventional statistical physics.

Quantum optics research is about the realization of a basic unit called QUBITs, and applying related concepts to quantum computing, quantum communication, and quantum circuits.
Ultrafast optics is about scrutinizing various dynamics and physical phenomena happening during a millionth of a second using atto-second laser pulses.

In the field of condensed matter physics, much studies are made on the topics of topological matter, strongly correlated materials, and nano-devices.

The POSTECH physics department is achieving world-class results in the following research fields: experimental/theoretical condensed matter physics, quantum optics/ultrafast optics, biophysics/complex systems, plasma/accelerator physics, and particle physics.
