Stable and unstable trajectories in a dipolar chain

A small number of XY magnetic dipoles are subject to an external magnetic field for studying the origin of their collective magnetic response.

Time scales in the thermal dynamics of magnetic dipolar clusters

Solution of the Langevin equation for a set of interacting x-y dipoles allows the identification of the time scales and correlation length that reveal how interactions, temperature, damping and inertia may determine the frequency modes of edge and bulk magnetic mesospins in artificial dipolar systems.

Boosted W and Z tagging with jet charge and deep learning

Demostration that the classification of boosted, hadronically decaying, weak gauge bosons can be significantly improved over traditional cut-based and boosted decision tree-based methods using deep learning and the jet charge variable.

Magnetoelectric effect in dipolar clusters

Study about the combination of the anisotropy of magnetic interactions and the point symmetry of finite solids in the study of dipolar clusters as new basic units for multiferroics metamaterials. It is found that the clusters carry spin current and that they manifest the magnetoelectric effect.

TOI-677b: A Warm Jupiter (P = 11.2 days) on an Eccentric Orbit Transiting a Late F-type Star

Discovery of a warm transiting gas giant using the data from the TESS mission and a number of spectrrographs in Chile. Part of a key project of our group to characterize gas giants with long (P>10 d) periods.

Resonant interaction between dispersive gravitational waves and scalar massive particles

The Klein-Gordon equation is solved in the curved background spacetime created by a dispersive gravitational wave. Unlike solutions of perturbed Einstein equations in vacuum, dispersive gravitational waves do not travel exactly at the speed of light. As a consequence, the gravitational wave can resonantly exchange energy with scalar massive particles.
