离散时间量子场论与变形超维拉索罗代数

Discrete-Time Quantum Field Theory and the Deformed Super Virasoro Algebra

Masud Chaichian, Peter Presnajder

摘要:

我们表明,Virasoro和超级维拉索罗代数,早期构造的抽象数学背景下,出现威克旋转后,在一个圆上的离散时间自由场模型的精确治疗。变形参数是$e^λ$,其中$λ=τ/ρ$是离散时间尺度$τ$与紧致空间的半径$ρ$的比值。

英文摘要:

We show that the deformations of Virasoro and super Virasoro algebra, constructed earlier on an abstract mathematical background, emerge after Wick rotation, within an exact treatment of discrete-time free field models on a circle. The deformation parameter is $e^λ$, where $λ=τ/ρ$ is the ratio of the discrete-time scale $τ$ and the radius $ρ$ of the compact space.
