阻抗耦合Luttinger液体的精确格林函数和玻色化

Exact Green's functions and Bosonization of a Luttinger liquid coupled to impedances

K-V Pham

摘要:

本文计算了有限尺寸Luttinger液体(LL)在零温和有限温下与阻抗相连的精确格林函数。本文证明了具有阻抗边界条件(IBC)的LL的玻色化是成立的。LL与开放的边界条件(诺依曼和狄利克雷的情况下)明确恢复为一个特殊的限制时,有无穷大的阻抗。此外,当阻抗等于Luttinger液体的特性阻抗时,则有限Luttinger液体被示出为有效地等效于无限Luttinger液体。

英文摘要:

The exact Green's functions of a finite-size Luttinger Liquid (LL) connected to impedances are computed at zero and finite temperature. Bosonization for a LL with Impedance boundary conditions (IBC) is proven to hold. The LL with open boundary conditions (for both Neumann and Dirichlet cases) is explicitly recovered as a special limit when one has infinite impedances. Additionally when the impedances are equal to the characteristic impedance of the Luttinger liquid then the finite Luttinger liquid is shown to be effectively equivalent to an infinite Luttinger liquid.
