제목:
Chirality, Spin, and Orbital in DNA-type Chiral Materials from a Quantum Perspective

초록:
In chemistry and biochemistry, chirality represents structural asymmetry characterized by non-superimposable mirror images, as in DNA. In physics, however, chirality commonly refers to the spin–momentum locking of a particle or quasiparticle in momentum space. While seemingly unrelated, these notions of chirality can be connected: chiral information can transfer from atomic structures to electronic states by inducing large spin polarization in electrons passing through chiral molecules (e.g., DNA). This phenomenon is known as chirality-induced spin selectivity (CISS).
In this talk, I will introduce our theoretical understanding of CISS, together with recent experimental progress on chiral spintronics and chiral optoelectronics.
