Quantum Electron Correlation & Transport Theory Group
Welcome to QECT lab @ KAIST led by Prof. Heung-Sun Sim!
Broadly speaking, we are theoretical physicists who study exciting quantum phenomena in condensed matter systems, employing diverse analytical and numerical techniques. See Research for more details.
We are collaborating with various theory and experimental groups all over the world, including members of Center for Quantum Coherence in Condensed Matter, also led by Prof. H.-S. Sim.
Open Positions
We are currently looking for highly motivated students who will explore exciting quantum worlds together. Don't hesitate to contact Prof. H.-S. Sim (hs_sim at kaist.ac.kr) if you have any inquiry.
양자세계를 함께 탐험할 동료들을 구하고 있습니다. 관심이 있으신 분들은 교수님(hs_sim at kaist.ac.kr), 혹은 랩장 (윤기범, kbyun97 at kaist.ac.kr)에게 편하게 연락주세요 :)
