Distinct Structural Dynamics of the Semiquinone State Define a Signalling Pathway in Avian Cryptochrome
Monika Kish, Suchitra Pradhan, Jessica L. Ramsay +3
The light-dependent magnetic compass of night-migratory songbirds is widely hypothesized to rely on the radical pair mechanism within retinal cryptochrome. However, bridging the me…
Signals too small to sense: Physical and information-theoretic limits to induction-based magnetoreception in birds
Daniel R. Kattnig
A recent study [Science 2025, eaea6425] proposes that magnetoreception in pigeons may arise from electromagnetic induction within the semicircular canals of the inner ear. In this…
Interradical motion can push magnetosensing precision towards quantum limits
Luke D. Smith, Farhan T. Chowdhury, Jonas Glatthard +1
Magnetosensitive spin-correlated radical-pairs (SCRPs) offer a promising platform for noise-robust quantum metrology. However, unavoidable interradical interactions, such as electr…
Engineering the uncontrollable: Steering noisy spin-correlated radical-pairs with coherent and incoherent control
Farhan T. Chowdhury, Luke D. Smith, Daniel R. Kattnig
The quantum control of spin-correlated radical pairs (SCRPs) holds promise for the targeted manipulation of magnetic field effects, with potential applications ranging from the des…
Chirality-bolstered quantum Zeno effect enhances radical pair-based magnetoreception
Luke D. Smith, Sukesh Tallapudi, Matt C. J. Denton +1
Radical pairs in the flavoprotein cryptochrome are central to various magnetically sensitive biological processes, including the proposed mechanism of avian magnetoreception. Crypt…
Fröhlich versus Bose-Einstein Condensation in Pumped Bosonic Systems
Wenhao Xu, Andrey A. Bagrov, Farhan T. Chowdhury +4
Magnon-condensation, which emerges in pumped bosonic systems at room temperature, continues to garner great interest for its long-lived coherence. While traditionally formulated in…
