4. 제목: 토토 사이트 순위 current, chirality, topological excitations, and broken symmetries in nanostructures

토토 사이트 순위 current acts as a key player in quantum 토토 사이트 순위tronics attracting enormous attention from chemistry and even biology as well as other communities of condensed matter physics these days.  Since 토토 사이트 순위 is a relativistic quantum mechanical attribute, it can be coupled to a transverse electric field through 토토 사이트 순위-orbit interaction thus acquiring chirality in various broken symmetry systems.  As the chiral 토토 사이트 순위 travels through chiral nanostructures that have broken inversion or mirror symmetry, the moving 토토 사이트 순위 gets polarized.  This is called chiral induced 토토 사이트 순위 selectivity (CISS) [1] that serves as an underlying mechanism in chiral molecule 토토 사이트 순위tronics exhibiting numerous intriguing phenomena and potential applications [2].  On the other hand, the 토토 사이트 순위 current can actively influence topological chiral excitations like magnetic domain walls in inversion symmetry broken magnetic nanostructures in the form of emergent torque and phenomena such as chiral 토토 사이트 순위-orbit torque [3], exchange coupling torque [4], and chiral exchange drag [5].  Note that the 토토 사이트 순위 current gets effectively relaxed through various dissipation channels, particularly, 토토 사이트 순위-pumping at the interfaces with heavy metals or even superconductors in an exotic manner [6].  In this seminar, I will talk about the recent advances in the vibrant studies on “토토 사이트 순위 Current” from broken mirror/inversion and time-reversal symmetries providing the outlook of potential applications with new functionalities.  In the end of the talk, I will present my detailed research topics, plans, roadmaps, and vision.
