Previous work has shown that time-reversal symmetric Weyl semimetals with a quadrupolar arrangement of first-order Weyl nodes exhibit a mixed crystalline-electromagnetic response …
We propose a novel way of modulating exceptional topology by implementing Floquet engineering in non-Hermitian (NH) systems. We introduce Floquet exceptional topological …

We develop non-Hermitian counterpart of a new class of collinear magnets, dubbed altermagnets, delineated by net zero magnetization with momentum-dependent spin …
