Magnetism plays a pivotal role in many biological systems. However, the intensity of the
magnetic forces exerted between magnetic bodies is usually low, which demands the …

Abstract The approach by Ettore Majorana for non-adiabatic transitions between two quasi-
crossing levels is revisited and significantly extended. We rederive the transition probability …

A popular hypothesis ascribes magnetoreception to a magnetosensitive recombination
reaction of a pair of radicals in the protein cryptochrome. Many theoretical studies of this …

Quantum biology is a modern field of research that aims to understand how quantum effects
can affect the chemistry underlying various biological processes. This paper reviews several …

This study explores the impact of thermal motion on the magnetic compass mechanism in
migratory birds, focusing on the radical pair mechanism within cryptochrome photoreceptors …

We realize arbitrary-wave-form-based control of spin-selective recombination reactions of
radical pairs in the low-magnetic-field regime. To this end, we extend the gradient-ascent …

The chemical reactivity of radical pairs is strongly influenced by the interactions of electronic
and nuclear spins. A detailed understanding of these effects requires a quantum description …

Quantum sensing enables the ultimate precision attainable in parameter estimation.
Circumstantial evidence suggests that certain organisms, most notably migratory songbirds …

Magnetoreception, the ability to sense magnetic fields, is widespread in animals but remains
poorly understood. The leading model links this ability in migratory birds to the photo …

Electron spin relaxation is, on many occasions, considered an elephant in the room that
challenges the idea of a radical-pair compass, a leading hypothesis for the navigation of …
