Here we find that pressure changes hopping processes within the same Sn-Ba-Sn layer leading to the appearance of a new topological nodal line, without breaking the PT symmetry responsible of the stability of the nodal lines. This is in contrast to the case of ZrSiS, where it has been ...
Recently, we have reported a class of simplified mimics of the eusynstyelamides, where the complex dihydroxybutyrolactam ring is replaced by a barbiturate scaffold16,17. This scaffold is rigid and can easily symmetry be modified with different cationic and no stereogenic centers, which iamnp...
