State Transitions and Decoherence in the Avian Compass

open access: yes, 2015
The radical pair model has been successful in explaining behavioral characteristics of the geomagnetic compass believed to underlie the navigation capability of certain avian species.

Spreading Electron Density Thin: Increasing the Chromophore Size in Polyaromatic Wires Decreases Interchromophoric Electronic Coupling [PDF]

open access: yes, 2018
The development of novel polychromophoric materials using extended polycyclic aromatic hydrocarbons as a single large chromophore holds promise for long-range charge-transfer applications in photovoltaic devices and molecular electronics.

Scheme for Detection of Single-Molecule Radical Pair Reaction Using Spin in Diamond. [PDF]

open access: yesPhysical Review Letters, 2016
The radical pair reaction underlies the magnetic field sensitivity of chemical reactions and is suggested to play an important role in both chemistry and biology.

Statistical Amplification of the Effects of Weak Magnetic Fields in Cellular Translation

open access: yesCells, 2023
We assume that the enzymatic processes of recognition of amino acids and their addition to the synthesized molecule in cellular translation include the formation of intermediate pairs of radicals with spin-correlated electrons.

Coherent chemical kinetics as quantum walks II: Radical-pair reactions in Arabidopsis thaliana

open access: yes, 2015
We apply the quantum-walk approach recently proposed in arXiv:quant-ph-1506.04213 to a radical-pair reaction where realistic estimates for the intermediate transition rates are available.

Avian magnetoreception model realized by coupling a magnetite-based mechanism with a radical-pair-based mechanism [PDF]

open access: yesChinese Physics B, 2013
Many animal species were verified to use geomagnetic field for their navigation, but the biophysical mechanism of magnetoreception has remained enigmatic. This paper presents a special biophysical model that consists of magnetite-based and radical-pair-based mechanisms for avian magnetoreception. The amplitude of the resultant magnetic field around the

Cryptochrome mediates light-dependent magnetosensitivity of Drosophila's circadian clock.

open access: yesPLoS Biology, 2009
Since 1960, magnetic fields have been discussed as Zeitgebers for circadian clocks, but the mechanism by which clocks perceive and process magnetic information has remained unknown.

A combined "electrochemical-frustrated Lewis pair" approach to hydrogen activation: surface catalytic effects at platinum electrodes [PDF]

open access: yes, 2014
Herein, we extend our “combined electrochemical–frustrated Lewis pair” approach to include Pt electrode surfaces for the first time. We found that the voltammetric response of an electrochemical–frustrated Lewis pair (FLP) system involving the B(C6F5)3 ...

Activation of Cryptochrome 4 from Atlantic Herring

open access: yesBiology
Marine fish migrate long distances up to hundreds or even thousands of kilometers for various reasons that include seasonal dependencies, feeding, or reproduction. The ability to perceive the geomagnetic field, called magnetoreception, is one of the many

Sensitive Chemical Compass Assisted by Quantum Criticality

open access: yes, 2011
The radical-pair-based chemical reaction could be used by birds for the navigation via the geomagnetic direction. An inherent physical mechanism is that the quantum coherent transition from a singlet state to triplet states of the radical pair could ...
