标题： Comments on photonic shells

摘要： 我们详细研究了无穷薄的静态圆柱壳的特殊情况，该壳由在圆测地线路径上反向旋转光子组成，将闵可夫斯基时空的两部分分开——一部分在壳内，另一部分在壳外——并与由位于两段平坦时空之间的壳内的圆测地线上的反向旋转零粒子形成的静态盘壳进行了比较。 有人可能会问，这两种情况是否实际上并不是一回事。 显示英文摘要

摘要： We investigate in detail the special case of an infinitely thin static cylindrical shell composed of counter-rotating photons on circular geodetical paths separating two distinct parts of Minkowski spacetimes--one inside and the other outside the shell--and compare it to a static disk shell formed by null particles counter-rotating on circular geodesics within the shell located between two sections of flat spacetime. One might ask whether the two cases are not, in fact, merely one.
