摘要:

动力学约化模型提出了解决量子力学中测量问题的方法:波函数的坍缩成为一个物理过程。我们计算了衰变和动力学约化模型的预言,提出了解决量子力学中测量问题的方法:波函数的坍缩成为一个物理过程。计算了两种最有希望的坍缩模型,即具有普适位置局域化的量子力学(QMUPL)模型和质量比例CSL(Continuous Spontaneous Localization)模型对衰变和味振荡中性介子的预言.我们的研究结果表明:(i)对这两种塌缩模型所依据的噪声场的假设具有很强的敏感性;(ii)在特定的假设下,CSL的情况甚至可以恢复衰变动力学。这又允许仅基于振荡的测量值(质量差)和衰减常数的测量值来预测有效塌陷速率。四种类型的中性介子($K$ -介子、$D$ -介子、$B_d$ -介子、$B_s$ -介子)令人惊讶地导致与Adler(2007)和Ghirardi-Rimini-Weber(1986)提出的范围相当的范围。我们的研究结果表明,这些系统在高能量是非常敏感的标准量子理论的可能修改,使他们成为一个非常强大的实验室,以排除某些崩溃的情况下,研究解决测量问题的详细物理过程。

英文摘要:

Dynamical reduction models propose a solution to the measurement problem in quantum mechanics: the collapse of the wave function becomes a physical process. We compute the predictions to decaying and Dynamical reduction models propose a solution to the measurement problem in quantum mechanics: the collapse of the wave function becomes a physical process. We compute the predictions to decaying and flavor--oscillating neutral mesons for the two most promising collapse models, the QMUPL (Quantum Mechanics with Universal Position Localization) model and the mass-proportional CSL (Continuous Spontaneous Localization) model. Our results are showing (i) a strong sensitivity to the very assumptions of the noise field underlying those two collapse models and (ii) under particular assumptions the CSL case allows even to recover the decay dynamics. This in turn allows to predict the effective collapse rates solely based on the measured values for the oscillation (mass differences) and the measured values of the decay constants. The four types of neutral mesons ($K$-meson, $D$-meson, $B_d$-meson, $B_s$-meson) lead surprisingly to ranges comparable to those put forward by Adler (2007) and Ghirardi-Rimini-Weber (1986). Our results show that these systems at high energies are very sensitive to possible modifications of the standard quantum theory making them a very powerful laboratory to rule out certain collapse scenarios and studying the detailed physical processes solving the measurement problem.
