Nature Physics - Going randomNow, Josh Izaac et al. show that this needn't be the case: by taking advantage of parity–time (PT)-symmetry, which emerges in non-Hermitian systems with gain and ...

Vertices and edges of the same color and shape in a graph are mapped to each other by a symmetry permutation preserving the structure of data.

Research from all publishers Recent investigations have deepened our understanding of Cayley graphs on finite simple groups by focusing on the classification of highly symmetric instances. Studies ...
