Enhanced higher harmonic generation from nodal topology
Ching Hua Lee, Han Hoe Yap, Tommy Tai +3
Among topological materials, nodal loop semimetals (NLSMs) are arguably the most topologically sophisticated, with their valence and conduction bands intersecting along arbitrarily…

Tidal surface states as fingerprints of non-Hermitian nodal knot metals
Xiao Zhang, Guangjie Li, Yuhan Liu +3
Non-Hermitian nodal knot metals (NKMs) contains intricate complex-valued energy bands gives rise to knotted exceptional loops and new topological surface states. We introduce a for…
