研究了金属栅对相互作用的一维电子液体低能特性的耗散。作为到栅极的距离的函数，或者电线中的电子密度，系统可以经历从Tomonaga-Luttinger液体到两种耗散相的量子相变，其中一种具有有限的空间相关长度。我们还定义了一个双重模型，它描述了一个有吸引力的一维金属与一个肮脏的金属铅的约瑟夫森耦合。
The dissipation induced by a metallic gate on the low-energy properties of interacting 1D electron liquids is studied. As a function of the distance to the gate, or the electron density in the wire, the system can undergo a quantum phase transition from a Tomonaga-Luttinger liquid to two kinds of dissipative phases, one of them with a finite spatial correlation length. We also define a dual model, which describes an attractive one-dimensional metal with a Josephson coupling to a dirty metallic lead.
