Simulating multi-node Weyl semimetals in a Mixed Floquet lattice
The episode discusses a paper simulating multi-node Weyl semimetals in a mixed Floquet lattice. The hosts explain how momentum-resolved Chern numbers can detect Weyl nodes, but this method does not fully reproduce the static phase diagram due to a topological obstruction involving gapped pump invariants. This suggests using these invariants to map out where Weyl nodes exist.
