Two-Loop QCD Corrections to the Heavy Quark Form Factors: Anomaly Contributions
, 2005 We present closed analytic expressions for the order $\alpha_s^2$ triangle diagram contributions to the matrix elements of the singlet and non-singlet axial vector currents between the vacuum and a quark-antiquark state.

Design of Small Intramolecular Singlet Fission Chromophore: An Azaborine Candidate and General Small Size Effects [PDF]
, 2016 We report the first attempt to design small intramolecular singlet fission chromophores, with the aid of quantum chemistry and explicitly simulating the time evolution of state populations using quantum dynamics method.

Bioorthogonal Engineering of Cellular Microenvironments Using Isonitrile Ligations
Advanced Functional Materials, EarlyView.Highly selective chemistries are required for fabrication and post‐cross–linking modification of cell‐encapsulating hydrogels used in tissue engineering applications. Isonitrile ligation reactions represent a promising class of bioorthogonal chemistries for engineering hydrogel‐based cellular microenvironments. Isonitrile‐based hydrogels are stable and

Investigation of the spin-forbidden process in thymine [PDF]
Hemijska Industrija, 2012 The intersystem crossing rate from the lowest singlet to the lowest triplet state of thymine was studied by means of the ab initio methods. The rate was calculated employing the time-dependent approach based on the correlation function.

Kondo tunneling through real and artificial molecules
, 2000 When a cerocene molecule is chemisorbed on metallic substrate, or when an asymmetric double dot is hybridized with itinerant electrons, its singlet ground state crosses its lowly excited triplet state, leading to a competition between the Zhang-Rice ...

Photophysical Property of Sanguinarine in the Excited Singlet State [PDF]
Photochemistry and Photobiology, 1992 Abstract—The photophysical property of the alkanolamine form of sanguinarine has been studied in aqueous and organic medium under various environmental conditions from the measurement of absorption, fluorescence and NMR spectroscopy. Alkanolamine fluorescence shows an excitation time dependent fluorescence quenching and the rate of quenching increases ...

Advanced Functional Materials, EarlyView.This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Singlet-Triplet Physics and Shell Filling in Carbon Nanotube Double Quantum Dots
, 2007 An artifcial two-atomic molecule, also called a double quantum dot (DQD), is an ideal system for exploring few electron physics. Spin-entanglement between just two electrons can be explored in such systems where singlet and triplet states are accessible.
