이번 학기 콜로퀴움은 학교의 권고를 따라, 사회적 거리두기 단계와 연계하여 온라인 혹은 오프라인(온라인 방송 병행)으로 운영될 예정입니다.

다섯번째 강연에는 KIAS의 박권 교수님을 모시고 콜로퀴움을 개최하오니, 학과 구성원 여러분의 많은 참여를 부탁 드립니다.

코로나19 확산방지를 위해 다과는 제공하지 않습니다.

 5. Abstract: One of the most important features of quantum mechanics is the formation of standing waves, or energy eigenstates via the constructive interference of wave functions. In fact, this is the underlying principle for the existence of atoms and, for that matter, all matters in the universe. In condensed matter systems, the constructive interference can occur in macroscopic scales, giving rise to various different forms of oscillatory behaviors collectively known as quantum oscillation. In this talk, I would like to talk about a new form of quantum oscillation that can occur in Weyl semimetals under electric fields. Specifically, it is shown that there is a rich structure in the chiral anomaly transport in Weyl semimetals, including the negative magnetoresistance, the non-Ohmic behavior, the Esaki-Tsu peak, and finally the resonant oscillation of the dc electric current as a function of electric fields, called the electric quantum oscillation.
