transitionphasetransitionThermodynamic conventions suffer from describing dynamical distinctions,especially when the structural and energetic changes induced by rare events are insignificant.By using the ensemble theory in the trajectory space,we present a statistical approach to address this problem.Rather than...

spin-1/2 Ising system under the presence of a time-varying (sinusoidal) external magnetic field within the path probability method (PPM) of Kikuchi and we observe that the PPM gives exactly the same result as with the Glauber-type stochastic dynamics based on the mean-field theory (DMFT). ...
By developing a mean-field theory, which we verify by simulations, we find coupled collective phenomena, including multistability, regions of coexistence, and macroscopic chaos. In interdependent dynamics, in particular, we observe hysteretic behaviours with abrupt (hybrid and explosive) transitions, ...
The concepts of the conventional theory, mode-coupling, scaling, universality, and the renormalization group are introduced and are illustrated in the context of a simple example-the phase separation of a symmetric binary fluid. The renormalization group is then developed in some detail, and applied...
The spin-charge-family theory explains why are the scalar fields (the Higgs) doublets with respect to the weak and the hyper charge One Weyl representation of SO(13+1) contains, if analysed with respect to the charge and the spin groups of the standard model, left handed weak (SU(2)_{...
an inspection of Γ reveals a transition in the key physical ingredients that limit the dynamic mechanical output of muscle as animals get larger. Terrestrial scaling theory has traditionally focussed on the impact of the differential scaling of weight vs. muscle forces: Galileo famously speculated ab...
“troubled families,” the dynamic systems approach offers insights that can suggest more targeted interventions. For example, as discussed earlier, an increase in variability in parent-adolescent interactions and relationship disequilibrium appears to be “normative” preceding a new phase transition. ...
The author studies the qualitative properties of the solutions v of anordinary differential equation of the form (1)v ' +A(t,v)v=F(t,v), where A(t,v) is the infinitesimal generator of an analytic semigroup in a Banach space. Under suitable Hlder continuity assumptions on A and F, ...
The broaden-and-build theory of positive emotion posits that positive affect increases flexible cognitive processing and leads to enhanced integration of multi-featural information33,34. Furthermore, a growing body of literature has linked positive affect to enhanced associative memory28, possibly via ...
