DEPARTMENT OF PHYSICS, PUSAN NATIONAL UNIVERSITY

PUSAN NATIONAL UNIVERSITY

Founded in 1946, Pusan National University is the first national university of South Korea. Right after independence, with the help of a voluntary petition and fund raising by the citizens of Busan, which is the second largest city in the country, the first official law on the establishment of the university was legislated. Pusan National University pursues to educate world leading generations with emphasis on the values of truth, freedom and service. All those values are based on a humanitarian spirit. In its 70 years, Pusan National University has grown to establish four specialized campuses with 1,185 faculty members and 28,854 students (as of 2017). The university strives to become an academic hub for the region, opening a new corridor for research and education, starting from the northeastern end of the Eurasian continent, Busan.

DEPARTMENT OF PHYSICS

The Department of Physics was launched in 1951 as the Department of Mathematics and Physics in the College of Liberal Arts. The department aims to educate students in fundamental science by providing opportunities to acquire a solid background in a wide range of physics, so that students can contribute to the development of both better national and regional communities by advancing science and technology.

The Department of Physics provides a variety of course work, including condensed matter physics, particle and nuclear physics, astrophysics, statistical physics, and non-linear/atom optics. These courses seek to whet our curiosity about the world and beyond by exposing students to essential questions on nature, ranging from the macroscopic world, the Universe, to the microscopic world of elementary particles. Through internship programs, the department also encourages undergraduate students to participate in active fields of various research groups. Three different types of degree courses are offered, such as a BS degree course for undergraduate students, and MS, PhD, and MS/PhD combined courses for graduate students. In addition, MS/BS and MS/BS/PhD combined courses are also offered to promote consecutive studies in physics.

As of July 2018, there are currently 290 enrolled undergraduate students and 42 graduate students. One third of the undergraduate students is supported by various scholarship programs from the university and non-profit scholarship foundations. Graduate students are fully supported by Brain Korea 21 Plus (BK21+), TA (teaching assistant), and RA (research assistant) programs. There are 21 faculty members (including 2 non-tenure track faculty members), three research professors, and three research associates in the physics department, with annual research funds of 3 million USD yielding more than 150 publications per year, allowing our department to be ranked as one of the top ten physics departments in South Korea.

RESEARCH AREAS

Condensed Matter Physics
There are ten faculty members in the Condensed Matter Physics Group. The main research interests of the condensed matter physics group are the experimental realization and theoretical comprehension of multi- functional materials including multiferroic materials, magnets and superconductors with controlled dimensionality ranging from 3D bulk materials via 3D-2D interfaces to 2D crystals.

Young Cheol KIM explores fundamental electronic and magnetic properties of high-critical temperature superconductors.

Ho-Soon YANG investigates the characteristic physical phenomena that appear in nano-meter scale materials and are controlled via size and surface effects.

Bog Gi KIM studies not only fundamental science, but also industrial applications of transition-metal oxides and carbon nanotubes to organic light-emitting diodes and organic solar cells.

RESEARCH CENTERS

Research Center for Dielectric and Advanced Matter Physics (RCDAMP)
In 1991, Research Center for Dielectric and Advanced Matter Physics (RCDAMP) was launched by Prof. Minsoo CHANG (emeritus professor of the Department of Physics) as part of the Science Research Center (SRC) Project supported by the National Research Foundation (NRF) of Korea with 22 professors from 13 universities and more than 100 graduate students. During the first phase of the program, the ultimate goal of the center has been to create novel phenomena and functionality of dielectric materials, and hence to educate world-leading scientists of the field. Currently, seven faculty members participate in the program with strong collaborations with international institutes such as UC Berkeley (USA), Lawrence Berkeley National Laboratory (USA), J-PARC (Japan), Osaka Univ. (Japan), RIKEN (Japan) and Hokkaido Univ. (Japan).

Extreme Physics Research Center
Established in 2012, 14 faculty members of the physics department participate in the program to understand extreme phenomena in particle physics, nuclear physics, astrophysics, advanced materials, and statistical physics. Currently, the research center is operating with an annual funding of ~2 million USD, funded by various organizations including the NRF, and focuses on the initiation of collaborative work with other academic and industrial institutions.

STUDENT ACTIVITIES

Undergraduate students in the Department of Physics at Pusan National University have organized not only outreach programs, but also non-scientific activities that enrich their school lives.

Open Lab
Since 1997, undergraduate students have organized "Open Lab" as an outreach program for the public, primarily middle/high school students in Busan area. In May, undergraduate students design experimental setups, demonstrate physical phenomena, and encourage the public to participate in the actual demonstration. By doing so, they not only motivate themselves to pursue fundamental physics, but also attract and promote public interest in physics. Every year, thousands of middle/high school students, teachers, and the public participate in and enjoy the Open Lab event.

PaC
Stemming from an intra-department community, PaC has been organized by undergraduate students to study Physics using computers. PaC members also organize study-groups to help non-club members who want to learn computer software and hardware.

Haneul-Bae
Haneul-Bae is a combined word of Haneul and Bae, which mean the sky and a ship, respectively, in Korean, and symbolizes a ship flying the sky. Established by undergraduate student union of the physics department in the late 80s, Haneul-Bae has achieved excellent results in the national rocket launching competition for the last few decades. Recently, they have also expanded their achievements in activities related to observation and comprehension of celestial bodies. In addition, club members also participate in Open Lab as a project team to provide basic astronomical information to the public.

Sports Activities
Dunker and Big-Bang are basketball and soccer clubs, respectively, that have been organized by undergraduate students of physics department. Now they are expanding their members to include students from the College of Natural Sciences. They regularly participate in intramural competitions such as the Hyowon Cup.
