Coherent Control of Population Transfer via Linear Chirp in Liquid Solution: The Role of Motional Narrowing.

The journal of physical chemistry. A

McRobbie PL, Geva E.
PMID: 26595412
J Phys Chem A. 2016 May 19;120(19):3015-22. doi: 10.1021/acs.jpca.5b09736. Epub 2015 Dec 07.

The conditions under which linear chirp can be used to control population transfer between the electronic states of a chromophore dissolved in liquid solution are investigated. To this end, we model the chromophore as a two-state system with shifted...

Sci Rep. 2018 May 22;8(1):8011. doi: 10.1038/s41598-018-25363-2.

Motivated by multi-hop communication in unreliable wireless networks, we present a percolation theory for time-varying networks. We develop a renormalization group theory for a prototypical network on a regular grid, where individual links switch stochastically between active and inactive...

Flattening helices while keeping the handedness: On-surface cyclodehydrogenation of bishelicene enantiomers leads stereospecifically to (M,M) and (P,P) chiral planar polyaromatic hydrocarbons. This is followed by their homochiral aggregation into a 2D conglomerate. Thermally induced cyclodehydrogenation proceeds stereospecifically to chiral,...

Diastereoselective self-assembly of bisheptahelicene on Cu(111).

Stereochemical effects during two-dimensional crystallization of bisheptahelicene diastereomers on a Cu(111) surface have been studied with scanning tunnelling microscopy. The (M,M)- and (P,P)-enantiomers crystallize into a monolayer racemate lattice, whereas the (M,P)-diastereomers aggregate into their own monolayer phase.

Crystallization is still an important means for separating chiral molecules into their two different mirror-image isomers (enantiomers), yet remains poorly...
