Optimal currents of indistinguishable fermions — •Mattia Walschaers^1,2, Andreas Buchleitner², and Mark Fannes¹ — ¹Instituut voor Theoretische Fysica, KU Leuven, Celestijnenlaan 200D, 3001 Leuven, Belgium — ²Physikalisches Institut, Albert-Ludwigs-Universität Freiburg, D-79104 Freiburg, Germany

We study currents of indistinguishable particles, in disordered systems far from equlibrium. Our goal is to identify fundamental bounds to the particle flow, and design principles to saturate these bounds. In the fermionic case, for weak coupling between system and reservoirs, we introduce a symmetry-based mechanism to enhance the flow. This mechanism is broadly applicable provided the inter-particle interactions are small with respect to quantum statistical effects.
