Phase transitions in single neurons and neural populations: Critical slowing, anesthesia, and sleep cycles [PDF]
The firing of an action potential by a biological neuron represents a dramatic transition from small-scale linear stochastics (subthreshold voltage fluctuations) to gross-scale nonlinear dynamics (birth of a 1-ms voltage spike). In populations of neurons

Molecular screening for solid–solid phase transition by machine learning [PDF]
Solid–solid phase transition is a mechanism manifesting and regulating functionalities in molecular crystals. The phase transitions are generally found by chance empirically, and screening molecules theoretically to predict their existence is challenging.

Modelling general anaesthesia as a first-order phase transition in the cortex [PDF]
Since 1997 we have been developing a theoretical foundation for general anaesthesia. We have been able to demonstrate that the abrupt change in brain state broughton by anaesthetic drugs can be characterized as a first-order phase transition in the ...

On the Douglas-Kazakov phase transition
We give a rigorous proof of the fact that a phase transition discovered by Douglas and Kazakov in 1993 in the context of two-dimensional gauge theories occurs. This phase transition can be formulated in terms of the Brownian bridge on

Complexity, scaling, and a phase transition
We investigate the holographic complexity of CFTs compactified on a circle with a Wilson line, dual to magnetized solitons in AdS4 and AdS5. These theories have a confinement-deconfinement phase transition as a function of the Wilson line, and the ...

Phase Transitions in Phase Retrieval [PDF]
Consider a scenario in which an unknown signal is transformed by a known linear operator, and then the pointwise absolute value of the unknown output function is reported. This scenario appears in several applications, and the goal is to recover the unknown signal -- this is called phase retrieval. Phase retrieval has been a popular subject of research

Axiogenesis from SU(2) R phase transition
The baryon asymmetry of the universe may be explained by rotations of the QCD axion in field space and baryon number violating processes. We consider the minimal extension of the Standard Model by a non-Abelian gauge interaction, SU(2) R , whose ...

Bifurcations of transition states : morse bifurcations [PDF]
A transition state for a Hamiltonian system is a closed, invariant, oriented, codimension-2 submanifold of an energy level that can be spanned by two compact codimension-1 surfaces of unidirectional flux whose union, called a dividing surface, locally ...
