时空泡沫的Omega效应判别
The Omega Effect as a Discriminant for Space-Time Foam
摘要：
如果存在CPT破坏，介子工厂中产生的中性介子对的纠缠性质一般会受到影响。新的纠缠形式是欧米茄效应。引力退相干，由于时空泡沫，可能是从CPT不变性的偏差的一个途径。考虑了两种时空泡沫模型。一种是基于非临界弦论，能够以自然的方式产生新的相关性。另一种是基于热浴的范例，即使在行使对浴状态的完全自由选择时，也显示出令人惊讶的抵抗力
英文摘要：
If there is CPT violation, the nature of entanglement for neutral meson pairs produced in meson factories may, on general grounds, be affected. The new form of entanglement is the omega effect. Gravitational decoherence, due to space-time foam, may be one route for deviations from CPT invariance. Two models of space-time foam are considered. One, based on non-critical string theory, is able to produce the new correlations in a natural way. The other, based on the paradigm of thermal-like baths, is shown to be surprisingly resistant to producing the effect even on exercising a total freedom of choice for the state of the bath
