The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

uniaxial strain and off-resonant circularly polarized light with tunable incidence angle enable a controllable route to Floquet higher-order topology in graphene... realizing a Floquet second-order topological insulator.

C2weakest assumption

The high-frequency expansion for the effective Floquet Hamiltonian remains valid for the chosen drive frequency and the strained tight-binding model with Peierls coupling accurately captures the light-matter interaction without significant higher-order corrections.

C3one line summary

Uniaxial strain and obliquely incident circularly polarized light stabilize a Floquet second-order topological insulator in graphene featuring gapped edges and robust corner modes.
