Recently we have predicted a new quasiparticle - the angulon - which is formed when a quantum impurity (such as an electron, atom, or molecule) exchanges its orbital angular momentum with a many-particle environment (such as lattice phonons or a Fermi sea). [mehr]

To thermodynamically address quantum nanoscopic scenarios that involve very small thermal baths and strong system-bath correlation, we suggest a new framework that is based on the principle of passivity. [mehr]
