Coherence-Mediated Boundary Control of the Liouvillian Gap in Nonreciprocal Open Quantum Systems

We study a single-particle Lindblad lattice in which nonreciprocal incoherent hopping is combined with a tunable coherent boundary link. The link changes the Hamiltonian boundary condition while the incoherent jump rates are kept fixed, so it does not directly alter the diagonal population generator. Its effect on the...
