A proposal for a new kind of spontaneous collapse model

Résumé

Spontaneous collapse models are modifications of standard quantum mechanics in which a physical mechanism is responsible for the collapse of the wavefunction, thus providing a way to solve the so-called "measurement problem". However, they present great challenges when one tries to make them relativistic. Here, we propose a new kind of non-relativistic spontaneous collapse model whose relativistic version could be easier to obtain. In the non-relativistic regime, we show that this model can lead to a dynamics quite similar to that of the Ghirardi-Rimini-Weber model, by also naturally solving the problem of indistinguishable particles. Moreover, we can also obtain the same master equation of the well-known Continuous Spontaneous Localization models. Finally, we show how our proposed model solves the measurement problem in a manner conceptually similar to the Ghirardi-Rimini-Weber model.
