아래와 같이 세미나를 개최하오니 많이 참석해 주시기 바랍니다. 아 래 1. 제 목: Is Quantum Criticality a Key to Unconventional Superconductivity? 2. 연 사: 박 두 선 박사(미국 Los Alamos National Laboratory 연구원) 3. 일 시: 2006년 8월 17일(목요일)오전10:30 4. 장 소: 물리학과 세미나실 (31355호실) 5. 초 록: The proximity of a magnetic phase to superconductivity, commonly observed in unconventional superconductors, suggests magnetic fluctuations as a source of the binding of electron pairs and unusual normal state behavior. Recently, Curro et al. [1] showed universal scaling of the spin-lattice relaxation rates among disparate classes of unconventional superconductors, where the superconducting transition temperatures (Tc) differ by two orders of magnitude, indicating a common pairing mechanism among them. In this talk, I will show a striking similarity between the heavy fermion compound CeRhIn5 and high-Tc cuprates not only in the generic temperature-pressure (or doping in the cuprates) phase diagram, but also in specific aspects of unconventional superconductivity, such as the field-induced magnetic ordering deep in the superconducting state [2]. These observations bring new perspective of quantum criticality in unconventional superconductors. [1] N. J. Curro et al. Nature 434, 622 (2005) [2] Tuson Park et al., Nature 440, 65 (2006)
