质量耦合相对论自发坍缩模型

Mass-coupled relativistic spontaneous collapse models

Caitlin Jones, Giulio Gasbarri, Angelo Bassi

摘要:

目前还没有一个令人满意的相对论自发坍缩模型。在这里,我们展示了一个简单的推广的连续自发崩溃(CSL)模型的相对论框架的不可能性。我们考虑一个质量耦合模型,在非相对论极限下,这给出了CSL模型。我们证明了洛伦兹协变坍缩方程不能同时满足以下条件:i)避免能量发散率,ii)防止超光速信号。

英文摘要:

Currently there is not a satisfactory relativistic spontaneous collapse model. Here we show the impossibility of a simple generalization of the continuous spontaneous collapse (CSL) model to the relativistic framework. We consider a mass coupled model as in the non-relativistic limit this gives the CSL model. We show that a Lorentz covariant collapse equation cannot simultaneously satisfy the following conditions: i) To avoid a divergent rate of energy, ii) To prevent superluminal signaling.
