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
new!: 2017, online a video with a talk given at the ECEA4 conference on stochastic thermodynamics for active particles
new!: 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
new!: 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
new!: 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 )
new!: 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"
