Thermal stability of solitons in protein α-helices
Launching of Davydov solitons in protein α-helix spines
Quantum Information in Neural Systems
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.
The Fourier-Laplace Transform—A Conjugate Link Between the Material Brain and the Conscious Mind
It is shown that an underlying operator algebra facilitates the formulation of the conjugate relationship between energy-time and momentum-space, and implications from augmented general dilation analytic operator families provide novel information-based representations and yield a thermo-qubit syntax for communication, which are required to support the quantum Darwinian view of life.
Quantum information theoretic approach to the mind-brain problem.


Quantum tunneling of Davydov solitons through massive barriers
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
Energy transport in α-helical protein models: One-strand versus three-strand systems
We study the transport of vibrational energy in α-helix forms of proteins within the frame of a steric Davydov model. Our main objective is the comparison of the localization and transport properties
On the quantum dynamics of Davydov solitons in proteinα-helices
Quantum entanglement shared in hydrogen bonds and its usage as a resource in molecular recognition
Quantum tunneling events occurring through biochemical bonds are capable of generating quantum correlations between bonded systems, which in turn makes the conventional second law of thermodynamics
Proton tunnelling in hydrogen bonds and its implications in an induced-fit model of enzyme catalysis
The role of proton tunnelling in biological catalysis is investigated here within the frameworks of quantum information theory and thermodynamics and it is found that in this scenario the enzyme lowers the activation energy so much that there is no energy barrier left in the tautomerization, even if the quantum correlations quickly decay.
Solitons in alpha-helical proteins.
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.

Role of Backbone Dipole Interactions in the Formation of Secondary and Supersecondary Structures of Proteins
A generic solvated coarse-grained protein model that can be used to characterize the driving forces behind protein folding and the role of dipole–dipole and dipole-charge interactions in shaping the secondary and supersecondary structure of proteins is characterized.
