Controlling the direction of topological transport in a non-Hermitian time-reversal symmetric Floquet ladder
We propose a one-dimensional Floquet ladder that possesses two distinct topological transport channels with opposite directionality. The transport channels occur due to a Z2 non-Hermitian Floquet topological phase that is protected by time-reversal symmetry. The signatures of this phase are two pair...
