正则k-Minkowski时空

Canonical k-Minkowski Spacetime

Ludwik Dabrowski, Gherardo Piacitelli

摘要:

给出了关系[T,X_j] =(i/k)X_j,j=1,…,D,给。与上述关系的普适表示相关的RxR^d的正则量化(在外尔的意义上)本质上是“径向的”,这意味着它只涉及时间变量和到原点的距离;角度变量仍然是经典的。通过原点的时间轴是模型的一个谱奇点:在大尺度极限下,它与其余部分拓扑不相交。符号演算的发展,特别是有一个跟踪功能的符号。对于非常接近原点的局域态的适当选择,所有时空坐标的不确定性可以同时在希望中变小。相反,不确定性关系在“大”距离变得重要:普朗克尺度效应在LHC能量下应该是可见的,如果过程在时空原点周围1毫米(峰值标称光束尺寸的量级)的区域内传播。

英文摘要:

A complete classification of the regular representations of the relations [T,X_j] = (i/k)X_j, j=1,...,d, is given. The quantisation of RxR^d canonically (in the sense of Weyl) associated with the universal representation of the above relations is intrinsically "radial", this meaning that it only involves the time variable and the distance from the origin; angle variables remain classical. The time axis through the origin is a spectral singularity of the model: in the large scale limit it is topologically disjoint from the rest. The symbolic calculus is developed; in particular there is a trace functional on symbols. For suitable choices of states localised very close to the origin, the uncertainties of all spacetime coordinates can be made simultaneously small at wish. On the contrary, uncertainty relations become important at "large" distances: Planck scale effects should be visible at LHC energies, if processes are spread in a region of size 1mm (order of peak nominal beam size) around the origin of spacetime.
