Bell定理现有证明的不可靠性 被引量:2

作者 马光文 《郑州大学学报(自然科学版)》 CAS 1994年第4期30-35,共6页
在Bell定理的现有证明中普遍存在着如下两个疑点:(1)认定粒子对中两相关粒子始终处在隐变态空间中的同一点,即始终有相同的隐变数值;(2)认定局域性等价于粒子对中两相关粒子被相应探测器探测到的几率的独立性。此外,某些... 在Bell定理的现有证明中普遍存在着如下两个疑点:(1)认定粒子对中两相关粒子始终处在隐变态空间中的同一点,即始终有相同的隐变数值;(2)认定局域性等价于粒子对中两相关粒子被相应探测器探测到的几率的独立性。此外,某些证明还认定隐变数理论也必须接受诸如测量过程中波包塌缩等量子力学的标准观点。事实上没有任何理由,至少没有给出有力的论证,表明它应当如此。因此Bell定理的现有证明是不可靠的,目前断言所有的隐变数理论已被排除为时尚早. 展开更多

An inequality is deduced from local realism and a supplementary assumption. This inequality defines an experiment that can be actually performed with the present technology to test local hidden-variable models, and it is violated by quantum mechanics with a factor 1.92, while it can be simplified into a form where just two measurements are required. 展开更多

In this paper we theoretically report an unconventional quantum phase transition of a simple Lipkin- Meshkow-Glick model: an interacting collective spin system without external magnetic field. It is shown that this model with integer-spin can exhibit a flrst-order quantum phase transition between different disordered phases, and more intriguingly, possesses a hidden supersymmetry at the critical point. However, for half-integer spin we predict another flrst-order quantum phase transition between two different long-range-ordered phases with a vanishing energy gap, which is induced by the destructive topological quantum interference between the intanton and anti-instanton tunneling paths and accompanies spontaneously breaking of supersymmetry at the same critical point. We also show that, when the total spin-value varies from half-integer to integer this model can exhibit an abrupt variation of Berry phase from π to zero. 展开更多

As well known, all higher dimensional Kerr-NUT-Ads metrics with arbitrary rotation and NUT parameters in an asymptotically Ad S spacetime have a new hidden symmetry. In this paper, we show that in the near horizon,the isometry group is enhanced to include the dilatation and special conformal transformation, and find the conformal transformation contains the cosmological constant. It is demonstrated that for near horizon extremal Kerr-NUT-Ads(NHEK-N-Ad S) only one rank-2 Killing tensor decomposes into a quadratic combination of the Killing vectors in terms of conformal group, while the others are functionally independent. 展开更多
