--- res: bibo_abstract: - Organic materials are known to feature long spin-diffusion times, originating in a generally small spin–orbit coupling observed in these systems. From that perspective, chiral molecules acting as efficient spin selectors pose a puzzle that attracted a lot of attention in recent years. Here, we revisit the physical origins of chiral-induced spin selectivity (CISS) and propose a simple analytic minimal model to describe it. The model treats a chiral molecule as an anisotropic wire with molecular dipole moments aligned arbitrarily with respect to the wire’s axes and is therefore quite general. Importantly, it shows that the helical structure of the molecule is not necessary to observe CISS and other chiral nonhelical molecules can also be considered as potential candidates for the CISS effect. We also show that the suggested simple model captures the main characteristics of CISS observed in the experiment, without the need for additional constraints employed in the previous studies. The results pave the way for understanding other related physical phenomena where the CISS effect plays an essential role.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Areg foaf_name: Ghazaryan, Areg foaf_surname: Ghazaryan foaf_workInfoHomepage: http://www.librecat.org/personId=4AF46FD6-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-9666-3543 - foaf_Person: foaf_givenName: Yossi foaf_name: Paltiel, Yossi foaf_surname: Paltiel - foaf_Person: foaf_givenName: Mikhail foaf_name: Lemeshko, Mikhail foaf_surname: Lemeshko foaf_workInfoHomepage: http://www.librecat.org/personId=37CB05FA-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0002-6990-7802 bibo_doi: 10.1021/acs.jpcc.0c02584 bibo_issue: '21' bibo_volume: 124 dct_date: 2020^xs_gYear dct_identifier: - UT:000614616200006 dct_isPartOf: - http://id.crossref.org/issn/1932-7447 - http://id.crossref.org/issn/1932-7455 dct_language: eng dct_publisher: American Chemical Society@ dct_title: Analytic model of chiral-induced spin selectivity@ ...
