We address the effects of dissipative defects giving rise to a localizedparticle loss, in one-dimensional non-interacting lattice fermionic gasesconfined within a region of size $\ell$. We consider homogeneous systems withinhard walls and inhomogeneous systems where the particles are trapped byspace-dependent external potentials, such as harmonic traps. We model thedissipative particle-decay mechanism by Lindblad master equations governing thetime evolution of the density matrix. The resulting quantum dynamics isanalyzed in protocols starting from the ground state of the Hamiltonian for$N_0$ particles, then evolving under the effect of one dissipativeparticle-loss defect, for example at the center of the system. We study theinterplay between time, size $\ell$ and the number $N_0$ of initial particles,considering two different situations: (i) fixed number $N_0$ of initialparticles; (ii) fixed ratio $N_0/\ell$, corresponding to the thermodynamiclimit of the initial equilibrium state. We show that the quantum evolutions ofthe particle number and density develop various asymptotic and intermediatedynamic regimes, and nontrivial large-time states when the dissipativemechanism acts at the center of the system.
