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

네번째 강연에는 성균관대학교 물리학과 최광용 교수님을 모시고 콜로퀴움을 개최하오니, 학과 구성원 여러분의 많은 참여를 부탁 드립니다.

코로나19 확산방지를 위해 다과는 제공하지 않습니다.

1. Title: A tale of quantum magnets


2. Speaker: 최  광  용 교수님 (성균관대학교 물리학과)


3. Date & Time: Mar. 24. (Wed.) 2021.  4:30 PM

 
4. Place: Natural Science 1,  Room No. 31214


 5. Abstract: In everyday life, we experience four states of matter: gas, liquid, solid, and plasma. In extreme conditions, many more exotic states can be observed, for example, BEC of ultra-cold atoms, superconductivity, and neutron-degenerate matters in a neutron state. Quantum magnets are a versatile reservoir for harboring emergent quantum-correlated phenomena, which have no precedent in a particle system. The paradigmatic instances include spin liquid, magnetic monopole, and Majorana fermion. The spin liquid is a long-range quantum entangled state on a quantum level, which breaks neither time-reversal nor spin-rotational symmetry. Recently, the Kitaev honeycomb lattice is envisioned as an ideal host for Majorana quasiparticles that are created out of the spin liquid vacuum and, thereby, holds promise for the implementation of a decoherence-free quantum computer.
 
In this talk, I will introduce spin liquid in the context of topological order and then present our group’s endeavor to search the predicted exotic states of matter in a quantum spin system.
