One Dimension中的Anyons

Anyons in One Dimension

Martin Greiter

摘要:

我给一个非技术帐户的分数统计在一个维度。在具有周期性边界条件的系统中,任意子的交叉总是单向的,并且由任意子获得的分数相位$θ$引起相对动量${Δp =2π\hbar/L\, (|θ|/π+n)}$的间距的分数移位。分数位移$θ/π$是相互作用任意子的一个好量子数,尽管单粒子动量和非负整数$n$通常不是。

英文摘要:

I give a non-technical account of fractional statistics in one dimension. In systems with periodic boundary conditions, the crossing of anyons is always uni-directional, and the fractional phase $θ$ acquired by the anyons gives rise to fractional shifts in the spacings of the relative momenta, ${Δp =2π\hbar/L\, (|θ|/π+n)}$. The fractional shift $θ/π$ is a good quantum number of interacting anyons, even though the single particle momenta, and hence the non-negative integers $n$, are generally not.
