Ground-State Properties of a Local Sine-Gordon Model with Two Frequencies

Abstract

The local sine-Gordon model with two frequencies is studied by a variational method. The renormalization mass and classical field path are calculated. We find an Ising-like phase transition, which is analogous in the global sine-Gordon model with two frequencies. A full phase diagram is given.

Ground State Properties of a Local Sine-Gordon Model with Two Scatters

Chen Yu-Guang, Chen Hong, Yumei Zhang

We investigate the local sine-Gordon model with two scatters by a variational method. The renormalization mass is calculated. It is found that there is an Ising-like phase transition, which is analogous in the global sine-Gordon model with two frequencies. The renormalization mass can be modulated by the distance between the two scatters.

Variational Gaussian wave functional and the (1+1)-dimensional sine-Gordon model

Yumei Zhang, Bo-Wei Xu, Wen-Fa Lu

The (1+1)-dimensional sine-Gordon model is studied in the framework of the variational Gaussian wave functionals. The renormalized mass depends on two dimensionless parameters. In the phase diagram a first-order phase transition will replace the second-order phase transition for large bare mass. The spectrum of the two-particle states consists of a continuum of scattering states and the isolated values connected to the excitonlike bound states. The energy of the bound states and the phase shifts of the scattering states are explicitly calculated.

The local sine - Gordon model

Bo-Wei Xu, Yumei Zhang

Effects of spatial inhomogeneity in the one-dimensional quantum sine - Gordon model are treated by use of the variational Gaussian wave-functional method. The properties of the ground state and the phase diagram of the system are investigated in detail.

Renormalization Group Study of Ising Transition in Double-Frequency sine-Gordon Model

Ye Fei, Guo-Hui Ding, Xu Bo-wei

We utilize the renormalization group (RG) technique to analyze the Ising critical behavior in the double frequency sine-Gordon model. The one-loop RG equations obtained show unambiguously that there exist two Ising critical points besides the trivial Gaussian fixed point. The topology of the RG flows is obtained as well.

A Self-Consistent Treatment of the Kosterlitz-Thouless Transition of the Two-Dimensional Classical Sine-Gordon Model

T. Sakaguchi, Tsuguhiro Tamaribuchi, Satoshi Takada

The two-dimensional classical sine-Gordon model is investigated by using a two-parameter self-consistent renormalization method up to second order of renormalized vertices, where coupled self-consistent equations for renormalized mass m and renormalized temperature x are obtained. In high temperature region (x > 2), the self-consistent equations have a massless solution which stands for the existence of the Kosterlitz-Thouless phase, and lead to an equation for x which is the same as that given by José et al. and is consistent with the result of Wilson's renormalization group method. In low temperature region (x < 2), numerical calculation is carried out, and it is shown that the system is well described by the self-consistent harmonic approximation, which is a one-parameter (m) renormalization treatment, except near x = 2. Near x ≲ 2 our self-consistent equations have no solution, through this can be partly remedied by counting chain diagrams.
