Out-of-equilibrium phase re-entrance(s) in long-range interacting systems
No full textSystems with long-range interactions display a short-time relaxation toward quasistationary states (QSSs) whose lifetime increases with system size. The application of Lynden-Bell’s theory of “violent relaxation” to the Hamiltonian Mean Field model leads to the prediction of out-of-equilibrium first- and second-order phase transitions between homogeneous (zero magnetization) and inhomogeneous (nonzero magnetization) QSSs, as well as an interesting phenomenon of phase re-entrances. We compare these theoretical predictions with direct N-body numerical simulations. We confirm the existence of phase re-entrance in the typical parameter range predicted from Lynden-Bell’s theory, but also show that the picture is more complicated than initially thought. In particular, we exhibit the existence of secondary re-entrant phases: we find unmagnetized states in the theoretically magnetized region as well as persisting magnetized states in the theoretically unmagnetized region. We also report the existence of a region with negative specific heats for QSSs both in the numerical and analytical caloric curves
The Poem of Memory. "Triumphi"
No full textWriting of the "Triumphi" Fabio Finotti finds that its author undercuts a medieval idea of ascent to God in the structural progression from Love to Chastity, Death, Fame, Time, and Eternity. Here Petrarch programmatically counters Dante, transforming a universal, eschatological vision into a subjective, cultural and psychological experience

Prof. Tronchetti’s scholarly is primarily in the areas of international space law and public international law. His publications include two books and more than 20 articles in internationally peer-reviewed space law and policy journals, such as Space Policy, the German Journal of Air and Space Law, the Journal of Space Law, etc.
He holds a PhD in International Space Law (Leiden University) and an Advanced LL.M in International Relations (Bologna University, Italy). He is Member of the International Institute of Space Law (IISL), European Centre for Space Law (ECSL), and the Asian Society of International Law (ASIL). He is the recipient of the 2007 Diederiks-Verschoor award for the best paper submitted by an author not older than 40 years to the International Institute of Space Law (IISL) during the 58th International Astronautical Congress of the International Astronautical Federation (IAF).https://commons.erau.edu/stm-images/1076/thumbnail.jp
Negative Specific Heat in the Canonical Statistical Ensemble
No full textAccording to thermodynamics, the specific heat of Boltzmannian short-range interacting systems is a positive quantity. Less intuitive properties are instead displayed by systems characterized by long-range interactions. In that case, the sign of specific heat depends on the considered statistical ensemble: Negative specific heat can be found in isolated systems, which are studied in the framework of the microcanonical ensemble; on the other hand, it is generally recognized that a positive specific heat should always be measured in systems in contact with a thermal bath, for which the canonical ensemble is the appropriate one. We demonstrate that the latter assumption is not generally true: One can, in principle, measure negative specific heat also in the canonical ensemble if the system under scrutiny is non-Boltzmannian and/or out-of-equilibrium
Per un ritratto di André Tosel
No full textIn memory of André Tosel, who passed away last March 14th in his hometown Nice, «Gramsciana» publishes an article on Gramsci in France that he had sent to this journal as a contribution to the section «My Gramsci». The editor, Fabio Frosini, prefaces the text with a quick portrait of Tosel as a philosophy professor, an influential Marxist intellectual, a critic of contemporary capitalism, as well as the author of landmark books on Spinoza, Kant and Marx and, above all, one of the most important Gramsci scholars of the last 50 years

La visión científica del Dr. Fabio Castillo Figueroa
No full textHaving as main source the memories of the hours he spent with Fabio Castillo, the author of this article analyzes the components of the scientific vision of the illustrious former rector of the University of El Salvador. The thought of Fabio Castillo can be divided into his historical, agrarian, political-educational ideas, as well as those referring to the university institution. His project, still in force, transcends the university classrooms, his main aspiration was to transform the unjust Salvadoran reality.Teniendo como principal fuente las memorias de las horas que pasó con Fabio Castillo, el autor de este artículo analiza las componentes de la visión científica del ilustre ex rector de la Universidad de El Salvador.
