摘要

受随机广义不确定性原理的启发，我们提出了一个由Lorentz不变性破坏（LIV）场景下随机修正色散关系的量子化导出的Lindblad方程。这个框架使我们能够研究具有引力诱导纠缠的粒子系统中的退相干效应。考虑系统效应和随机效应，我们分析了LIV对纠缠（由并发量化）的影响。

LIV-decoherence on gravitational cat states

Inspired by approaches based on the stochastic generalized uncertainty principle, we propose a Lindblad equation derived from the quantization of a stochastic modified dispersion relation in a Lorentz Invariance Violation (LIV) scenario. This framework enables us to investigate decoherence effects in a system of particles exhibiting gravitationally induced entanglement. We analyze the impact of LIV on entanglement (quantified by concurrence) considering systematic and stochastic effects.
