Concerning the stability of biexcitons in hybrid HJ aggregates of π-conjugated polymers.
Frenkel excitons are the primary photoexcitations in organic semiconductors and are ultimately responsible for the optical properties of such materials. They are also predicted to form bound exciton…

Quantum Information in Neural Systems
TLDR
The presented results show that fast decoherence timescales could assist cognitive binding through quantum entanglement across extensive neural networks in the brain cortex, and show that quantum coherence of individual subsystems cannot be used for cognitive binding because it is a physical mechanism that leads to separability and non-interaction.

Solitons in alpha-helical proteins.
TLDR
It is argued that thesolitons studied by Scott are hybrid solitons and that the oscillations arise due to the helical symmetry of the system and result from the motion of the soliton along the alpha helix.
Quantum-Mechanical Derivation of the Davydov Equations for Multi-Quanta States
Davydov and Kislukha1 suggested in the 1970’s that nonlinear self-trapping could serve as a method of energy transport along quasi-one-dimensional chains of molecules. The problem was to explain how…

Ratchet effect of Davydov's solitons in nonlinear low-dimensional nanosystems
We study the ratchet behavior of polarons in diatomic molecular chains under the influence of an external electromagnetic field which is periodic in time. We show that in asymmetric chains a harmonic…
Influence of Heat Bath and Disorder on Davydov Solitons
With the help of the so-called /D2> state vector ansatz the dynamics of Davydov solitons is investigated. The soliton remains stable against aperiodicity in the sequences of masses, spring constants,…
Temperature effects on the Davydov soliton.
TLDR
This paper investigates the stability of Davydov solitons at biological temperatures and concludes that the Davydovo soliton is stable at 310 K.
Influence of heat bath and disorder in the sequence of amino acid masses on Davydov solitons
The theory of Davydov solitons for the energy transport in proteins is briefly summarised, using for the dynamics of the solitons the quantum equations of motion. To obtain a more realistic model for…

TLDR
This review looks at four areas of ‘quantum effects in biology’: biosystems that are very diverse in detail but possess some commonality: rates of a signal that can be calculated from a form of the ‘golden rule’, and protein–pigment (or ligand) complex systems, which may contain some degree of quantumeffect.
