假真空衰变的隧穿哈密顿表示:II。孤子-反孤子对产生的应用
The tunneling hamiltonian representation of false vaccuum decay: II. Application to soliton - anti soliton pair creation
摘要:
隧穿哈密顿量已被证明是一个有用的方法,在许多体物理学处理粒子隧道之间的不同状态表示为波函数。我们的问题是在这里应用我们在第一篇论文中所做的驱动sine-Gordon系统。在这里,我们适用于一般化的隧穿哈密顿量的电荷密度波输运问题,在其中被认为是标量量子场的波泛函的状态之间的隧穿。我们导出了与Zenier曲线相匹配的I-E曲线,Zenier曲线用于用符合假真空假设的波泛函拟合实验数据
英文摘要:
The tunneling hamiltonian has proven to be a useful method in many body physics to treat particle tunneling between different states represented as wavefunctions. Our problem is here applying what we did in the first paper to a driven sine-Gordon system. Here we apply a generalization of the tunneling Hamiltonian to charge density wave transport problems, in which tunneling between states which are wavefunctionals of a scalar quantum field are considered. We derive I-E curves which match Zenier curves used to fit data experimentally with wavefunctionals congruent with the false vacuum hypothesis
