Extraordinary resonant transmission in two-terminal fermionic transport

Abstract

We analyze conductance of a two-leg ladder connected with fermionic reservoirs, focusing on the decoherence effect induced by the reservoirs. In the absence of decoherence the system exhibits both bound states in the continuum and Fano resonances. We found that the Fano resonances in transmittance are robust against decoherence, at the same time decoherence prevents collapse of resonances induced by bound states in the continuum.
