提出了具有部分宇称-时间（PT）对称性的多维复光学势。通常的PT对称性要求势在复共轭和所有空间方向上的同时反射下是不变的。然而，我们表明，如果潜在的只是部分PT对称，即，它在复共轭和反射作用下在单一空间方向上是不变的，因此它也可以具有全实谱和连续孤子族。这些结果是建立解析和数值证实。
Multidimensional complex optical potentials with partial parity-time (PT) symmetry are proposed. The usual PT symmetry requires that the potential is invariant under complex conjugation and simultaneous reflection in all spatial directions. However, we show that if the potential is only partially PT symmetric, i.e., it is invariant under complex conjugation and reflection in a single spatial direction, then it can also possess all-real spectra and continuous families of solitons. These results are established analytically and corroborated numerically.
