Abstract

Effects of spatial inhomogeneity with symmetric potentials in 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 critical point of the system are investigated.

Theoretical Study of Tunneling Effect in One-dimensional Quantum Sine-Gordon Model

Yumei Zhang

The tunneling effect in one-dimensional quantum Sine-Gordon model is studied by variational Gaussian wave functional method. It is shown that the tunneling effect will disappear when one-dimensional Sine-Gordon model's length tends towards infinity. The tunneling effect only plays its role in one-dimensional quantum Sine-Gordon system with finite length.

SINE-GORDON MODEL AND GAUSSIAN WAVE FUNCTIONAL

Xu Bo-wei, Yumei Zhang, Wen-Fa Lu +1 more

With a general Gaussian wave functional, we study the ground states, one particle states, and two particle states of the sine-Gordon model. At the Coleman's critical point, the sine-Gordon system tends to a system of massless free bosons which possesses conformal symmetry. We also show that there exist bound states in two particle states as long as the renormalized mass remains finite.

The Critical Properties of a Modulated Quantum sine-Gordon Model

Wang Zhi-Guo, Zhang Yu-Mei

A new procedure of trial variational wave functional is proposed for investigating the mass renormalization and the local structure of the ground state of a one-dimensional quantum sine-Gordon model with linear spatial modulation, whose ground state differs from that without modulation. The phase diagram obtained in parameters plane shows that the vertical part of the boundary between soliton lattice phase and incommensurate (IC) phase with vanishing gap sticks at , the IC phase can only appear for and the IC phase regime is enlarged with increasing spatial modulation in the case of definite parameter . The transition is of the continuous type on the vertical part of the boundary, while it is of the first order on the boundary for .
