Large scale emergent properties of an autocatalytic reaction-diffusion model subject to noise
David Hochberg, Felipe Lesmes, Federico Moran +1
The non-equilibrium dynamic fluctuations of a stochastic version of the Gray-Scott (GS) model are studied analytically in leading order in perturbation theory by means of the dynam…
Phase diagram and influence of defects in the double perovskites
J. L. Alonso, L. A. Fernandez, F. Guinea +2
The phase diagram of the double perovskites of the type Sr_{2-x} La_x Fe Mo O_6 is analyzed, with and without disorder due to antisites. In addition to an homogeneous half metallic…
A class of chiral fermion models
J. L. Alonso, Ph. Boucaud, F. Lesmes +1
We study the relation between the Roma and Zaragoza proposals for chiral fermions on the lattice. The fermion action in the Roma approach is shown to be equivalent to one of the Za…
Roma versus Zaragoza
J. L. Alonso, Ph. Boucaud, F. Lesmes +1
The Roma and Zaragoza actions for chiral fermions on the lattice are shown to be essentially equivalent. The auxiliary fermion fields in the Roma model can be integrated out, and t…
Phase Diagram of An SU(2)xSU(2) Scalar-Fermion Model with Massless Decoupled Doublers
J. L. Alonso, F. Lesmes, E. Rivas +1
We present the phase structure of the chiral SU(2)xSU(2) scalar-fermion model on the lattice using the Zaragoza proposal for chiral fermions. The numerical result agrees with an an…
Phase Diagram of a Lattice Scalar-Fermion Model Using the Zaragoza Fermions
J. L. Alonso, Ph. Boucaud, F. Lesmes +1
We present a calculation of the phase diagram of a chiral Yukawa model with massless decoupled doublers, using a saddle point approach, both for small and larg…
