Аннотация: <jats:p>In the absence of decoherence and disorder the current of noninteracting fermionic particles across a finite lattice connecting two reservoirs (leads) with different chemical potentials is known to be ballistic. It is also known that decoherence suppresses this ballistic current. However, if decoherence is weak, the change Показать полностьюin the current can be undetectable. In this work we show that the effect of a weak decoherence can be amplified by orders of magnitude if the lattice has edge states. This allows us to use a lattice with edge states as a sensor for measuring the decoherence rate.</jats:p>
