Variational Description of Gibbs-Non-Gibbs Dynamical Transitions for Spin-Flip Systems with a Kac-Type Interaction
(Springer, 2014-07)
We continue our study of Gibbs-non-Gibbs dynamical transitions. In the present paper we consider a system of Ising spins on a large discrete torus with a Kac-type interaction subject to an independent spin-flip dynamics ...
Density-Profile Processes Describing Biological Signaling Networks: Almost Sure Convergence to Deterministic Trajectories
(SPRINGER, 2009)
We introduce jump processes in R(k), called density-profile processes, to model biological signaling networks. Our modeling setup describes the macroscopic evolution of a finite-size spin-flip model with k types of spins ...
Dynamics of chiral oscillations: a comparative analysis with spin flipping

Orbital and spin dynamics of intraband electrons in quantum rings driven by twisted light
(Optical Society of America, 2011-11)
We theoretically investigate the effect that twisted light has on the orbital and spin dynamics of electrons in quantum rings possessing sizable Rashba spin-orbit interaction. The system Hamiltonian for such a strongly ...

Nonequilibrium dynamics of the three-dimensional Edwards-Anderson spin-glass model with Gaussian couplings: strong heterogeneities and the backbone picture
(Springer, 2016-11)
We numerically study the three-dimensional Edwards-Anderson model with Gaussian couplings, focusing on the heterogeneities arising in its nonequilibrium dynamics. Results are analyzed in terms of the backbone picture, ...
RVB signatures in the spin dynamics of the square-lattice Heisenberg antiferromagnet
(IOP Publishing, 2016-03)
We investigate the spin dynamics of the square-lattice spin- 1/2 Heisenberg antiferromagnet by means of an improved mean-field Schwinger boson calculation. By identifying both, the long-range Neel and the RVB-like components ...
Experimental and theoretical evidences for the ice regime in planar artificial spin ices

Charge Ordering in a Pure Spin Model: Dipolar Spin Ice
(Amer Physical Soc, 2013-10-04)
We study the dipolar spin-ice model at fixed density of single excitations, rho, using a Monte Carlo algorithm where processes of creation and annihilation of such excitations are banned. In the limit of rho going to zero, ...
