Saddle scars: Existence and applications
A quantum scar is a wave function which displays an high intensity in the region of a classical unstable periodic orbit. Saddle scar are states related to the unstable harmonic motions along the stable manifold of a saddle point of the potential. Using a semiclassical method it is shown that, independently of the overall structure of the potential, the local dynamics of the saddle point is suff...
متن کاملHypertrophic scars and Keloids
The available treatment modalities for hypertrophic scars and keloids have very little success. Surgical treatment of these lesions without adjuvant therapy is also associated with high recurrence rate. Hypertrophic scars and keloids are the results of a series of cellular and molecular changes which their identification can guide us toward new treatment modalities which may decrease the ...

متن کاملValidated Saddle-Node Bifurcations and Applications to Lattice Dynamical Systems
The use of rigorous verification methods is a powerful tool which permits progress in the analysis of dynamical processes that is not possible using purely analytical techniques. In this paper we develop a set of tools for branch validation, which allows for the rigorous verification of branch behavior, bifurcation, and solution index on branches generated through a saddle-node bifurcation. Whi...
متن کاملShrinking Dimer Dynamics and Its Applications to Saddle Point Search
Saddle point search on an energy surface has broad applications in fields like materials science, physics, chemistry, and biology. In this paper, we present the shrinking dimer dynamics (SDD), a dynamic system which can be applied to locate a transition state on an energy surface corresponding to an index-1 saddle point where the Hessian has a negative eigenvalue. By searching for the saddle po...
