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.
CCQCN member Prof. I. Perakis in collaboration with a group of researchers, published a significant article in Nature Communications, entitled "Ultrafast observation of critical nematic fluctuations and giant magnetoelastic coupling in iron pnictides"
In agreement with theoretical predictions by QCN researchers, a new highly efficient mode of thermal conduction was discovered and presently investigated, namely heat transport by magnetic excitations in quasi one- dimensional (1D) insulating materials ...
