Probing the Spin-Coherency in Chiral Systems
Chiral molecules exhibit spin-dependent effects such as spin filtering. This effect shows long-distance and long-time processes which could indicate quantum coherency. The question of whether passing through chiral media preserves the phase is still unknown. The answer to that will be utilized to develop applications such as optical parallel computing, logic devices, quantum computing, and more. We are working toward probing the coherency of the CISS effect. In our systems, the coupling is controlled by chiral molecules, and room-temperature quantum states are induced by nanoparticles. We observe oscillations - CISS dynamic, to prove a phase correlation. This could be done by using high resolution time-dependent optical system and low-temperature magnetoresistance measurements.
