Collective modes of coupled phase oscillators with delayed coupling
(American Physical Society, 2012-04)
We study the effects of delayed coupling on timing and pattern formation in spatially extended systems of dynamic oscillators. Starting from a discrete lattice of coupled oscillators, we derive a generic continuum theory ...
Large long-range F-F indirect spin-spin coupling constants. Prediction of measurable F-F couplings over a few nanometers
(American Chemical Society, 2004-05)
Large long-range indirect nuclear spin coupling constants are of great interest for quantum computers. But they are rarely observed and are usually considered very small, unless the coupled nuclear spins are proximate in ...
Evolutionary coupling range varies widely among enzymes depending on selection pressure
(Cell Press, 2021-10-19)
Recent studies proposed that enzyme-active sites induce evolutionary constraints at long distances. The physical origin of such long-range evolutionary coupling is unknown. Here, I use a recent biophysical model of evolution ...
Correspondence between atomic levels in LS and jj couplings
(Taylor & Francis, 2019-04)
This work aims at determining the correspondence between LS and jj couplings for some typical configurations without explicitly calculating level energies. To understand this article, an introductory course on quantum ...
A Cooperation between Fluctuations and Spatial Coupling for Two Symmetry-Breakings in a Gradient System
(American Physical Society, 2015-12)
A zero-dimensional system that is affected by the field´s dependent fluctuations evolves toward field´s values in which the fluctuations´ effect is minimized. For a high enough noise intensity, it causes an exchange of ...
Chemical event chain model of coupled genetic oscillators
(American Physical Society, 2018-03)
We introduce a stochastic model of coupled genetic oscillators in which chains of chemical events involved in gene regulation and expression are represented as sequences of Poisson processes. We characterize steady states ...
Enhancing energy harvesting by coupling monostable oscillators
(Springer, 2017-02-15)
The performance of a ring of linearly coupled, monostable nonlinear oscillators is optimized towards its goal of acting as energy harvester – through piezoelectric transduction – of mesoscopic fluctuations, which are modeled ...
Strain energy change to the insertion of inclusions associated to a thermo-mechanical semi-coupled system
(Elsevier, 2013-01)
The topological derivative measures the sensitivity of a given shape functional with respect to an infinitesimal singular domain perturbation. According to the literature, the topological derivative has been fully developed ...
Comment on "Nonadiabatic couplings from the Kohn-Sham derivative matrix: Formulation by time-dependent density-functional theory and evaluation in the pseudopotential framework"
(American Physical Society, 2013-11)
The issue of the ab initio evaluation of the first-order nonadiabatic couplings (NAC's) is re-examined. In particular, a recent derivation in Phys. Rev. A 82, 062508 (2010) of the NAC's is corrected by performing an extension ...
Dynamics of mobile coupled phase oscillators
(American Physical Society, 2013-03-21)
We study the transient synchronization dynamics of locally coupled phase oscillators moving on a one-dimensional lattice. Analysis of spatial phase correlation shows that mobility speeds up relaxation of spatial modes and ...
