Abstract
We show that in a ring-shaped Luttinger Liquid (LL) in contact with an electron reservoir --- the chemical potential in the ring being controlled by a gate voltage --- both the average ring charge and the persistent current in the ring are step-like functions of at low temperatures. The step positions are determined by the LL parameter , which therefore can be directly measured. We study electrons both with and without spin, taking into account long-range interactions in the ring.
