Dynamic Multistability Effect in SQUID Metamaterials
QCN researchers have investigated numerically a two-dimensional SQUID metamaterial with and without quenched disorder and they have predicted multistability, which is a purely dynamic effect not related to the multistability known from hysteretic SQUIDs. These results show that SQUIDs can be used as fast, intrinsically switchable meta-atoms, for the construction of metamaterials with many potential applications, such as, for example, all-optical metamaterial switch.
G.D. Barmparis and G.P. Tsironis estimate the infection horizon of COVID-19 in eight countries, and predict successfully both the expected number of daily infections per country and the duration of the epidemic in each country.
