Power-law statistics and stellar rotational velocities in the Pleiades

In this paper we will show that, the non-gaussian statistics framework based on the Kaniadakis statistics is more appropriate to fit the observed distributions of projected rotational velocity measurements of stars in the Pleiades open cluster. To this end, we compare the results from the $\kappa$ and $q$-distributions with the Maxwellian.Comment: 13 pages, 3 figure

Thermodynamic, magnetic and transport properties of the repulsive Hubbard model on the kagome lattice

Over the past decades, magnetic frustration has been under intense debate due to its unusual properties. For instance, frustration in the kagome lattice suppresses long range spin correlations and it is expected to be a candidate for a spin liquid system. Therefore, with the advent of experiments with ultra-cold atoms, the interest for frustrated geometries has increased. Given this, in the present work we investigate the repulsive Hubbard model on the kagome lattice by unbiased quantum Monte Carlo simulations. We examine its thermodynamic properties, as well as the magnetic and transport response of the system at finite temperatures and different values of the repulsive interaction. From these results, we discuss the possible occurrence of adiabatic cooling, a quite important feature in ultra-cold systems, and the presence of a metal-to-insulator transition at a finite interaction strength. Our findings may guide future experiments in ultra-cold fermionic atoms on the kagome lattice.Comment: 8 pages, 11 figure

European transnational cooperation in the making

The European transnational cooperation process, implemented via the ongoing 15 EU INTERREG- B programmes, is integrated in the second objective of EU Cohesion Policy: European Territorial Cooperation. Aiming to promote better cooperation and regional development processes within the European Union by a joint approach to tackle common issues, the EU transnational cooperation programmes are key to tackling transnational development bottlenecks and to better exploring transnational territorial capitals. Currently, there are ongoing discussions within the European Commission to delimit the new EU Cohesion Policy post-2020 INTERREG-B programmes. In this context, this article summarises the main conclusions of four invited speakers of an international conference which took place on 21 June 2019 at the Instituto Universitário de Lisboa. The conference aimed to present some of the key contributions towards territorial development of the EU of EU Cohesion Policy and, in particular, of three INTERREG-B programmes: North West Europe (NWE), South West Europe (SUDOE), and the Atlantic Area.info:eu-repo/semantics/publishedVersio
