Vortragender: Prof. Dr. Peter Rabl von der TU-München

In this talk Professor Rabl will address the dissipative transport of bosonic particles along a 1D lattice with asymmetric hopping rates. Such a setting can be realized with cold atoms, long-lived polaritons in nanophotonic lattices, superconducting circuits and many other systems with incoherent, but number-conserving hopping processes. In spite of its simplicity, this transport model exhibits many surprising features that arise as a direct consequence of the asymmetry in the hopping rates and the bosonic particle statistics. Specifically, he will discuss the appearance of an unconventional Bose-condensation transition, which is induced by a thermal current through the system. In the second part he will then address the universal scaling of current fluctuations, an unexpected similarity between bosonic and fermionic transport and how this is connected to the physics of surface growth.
