new!: 2019, we (with Plati, Baldassarri, Gnoli and Gradenigo) have published on Phys. Rev. Lett, a numerical study of the full experimental setup for granular rotational diffusion, discovering a strong collective motion that emerges when density is large enough
new!: 2018, we (with Angelani, Baldassarri, Cecconi and Gnoli) have won a funding (150kEuro) for a project (MICROSORT) on the physics of sperm
new!: 2018, we (with Caprini, Bettolo Marconi and Vulpiani) have published on Phys. Rev. Lett a comment to a previous study on thermodynamics of active (living) matter, where we offer a possible solution to a debate about the proper definition of entropy production
new!: 2018, we (with Gnoli, De Arcangelis, Giacco, Lippiello, Pica Ciamarra and Sarracino) have published on Phys. Rev. Lett, a study of viscosity in dense granular media, which decreases abruptly at a thresold vibration frequency and is recovered at a larger vibration frequency
recent: 2017, online a video with a talk given at the ECEA4 conference on stochastic thermodynamics for active particles
recent: 2017, we (with Manacorda) have published on Phys. Rev. Lett, a study of a lattice model for inertial active particles which shows collective swarming, aster-like clusters and underdamped propagating waves
recent: 2017, we (with Sarracino and Vulpiani) have published a review paper on Physics Reports about the definition of temperature in and out of equilibrium in classical statistical mechanics
recent: 2017, we (with Bettolo and Maggi) have published a paper on Scientific Reports where entropy production and heat are connected - as in the Clausius relation - in a model of self-propelled (active) particles, like bacteria or sperm
(we have also compared our Clausius relation with other formula in a more recent paper )
recent: 2017, I am editing (with Sarracino and Vulpiani) a special issue of the "Entropy" journal on the theme "Thermodynamics and Statistical Mechanics of Small Systems"

2016, published on New J. Phys, an experimental and theoretical study of the response velocity of a 3d-printed "walker" moving on a vibrating plate (in collab. with N. Koumakis, A. Gnoli, C. Maggi and R. Di Leonardo)
2016, published on Phys. Rev. Lett, a numerical study of the response of an inertial particle in a "rotating" flow, with very strange nonlinear effects (in collab. with Cecconi, Sarracino and Vulpiani)
2016, published on Phys. Rev. Lett, an experiment on granular thermal convection induced only by dissipative lateral walls (in collab. with Gnoli, Pontuale and Vega-Reyes)
2015: Spring 2015 seminars: during the spring of 2015 we had a lucky sequence of three seminars given by young colleagues who - in the recent past - have worked in our group, and are now exploring new interesting paths in non-equilibrium statistical mechanics; following the above link you can retrieve the titles, abstracts and slides of the three seminars.
