[eng] This work focuses on the evaluation of the satisfaction of the Thermodynamic Uncertainty Relation that expresses a trade-off between dissipation and precision of a nonequilibrium current observable for a chiral system. It studies the case of a topological system with a quantum dot impurity acting under the influence of a Maxwell demon and how the influence of the demon can break the time-reversal symmetry of a Markov chain to avoid the lower bound of entropy production and current fluctuation for electrical currents
