The infinitely many zeros of stochastic coupled oscillators driven by random forces
(2017)
In this work, previous results concerning the infinitely many zeros of single stochastic oscillators driven by random forces are extended to the general class of coupled stochastic oscillators. We focus on three main ...
The effect of random coupling coefficients on decoherence
(World Scientific, 2010-03)
The aim of this letter is to analyze the effect on decoherence of the randomness of the coupling coefficients involved in the interaction Hamiltonian. By studying the spin-bath model with computer simulations, we show that ...
Pressure response of amide one-bond J-couplings in model peptides and proteins
(SpringerDordrecht, 2014-09)
The pressure dependence of the one-bond indirect spin-spin coupling constants 1 J N-H was studied in the protected tetrapeptides Ac-Gly-Gly-Xxx-Ala-NH2 (with Xxx being one of the 20 proteinogenic amino acids). The response ...
Strong-randomness infinite-coupling phase in a random quantum spin chain
(American Physical Society - APSCollege Park, 2014-01)
We study the ground-state phase diagram of the Ashkin-Teller random quantum spin chain by means of a generalization of the strong-disorder renormalization group. In addition to the conventional paramagnetic and ferromagnetic ...
Localization for a Random Walk in Slowly Decreasing Random Potential

An integro-differential equation for dynamical systems with diffusion-mediated coupling
(Springer, 2020-06-09)
Many systems of biological interest can be modeled as pointlike oscillators whose coupling is mediated by the diffusion of some substance. This coupling occurs because the dynamics of each oscillator is influenced by the ...
