Riccardo Falcone, Claudio Conti

AI总结:

针对非惯性观察者缺乏 Minkowski 粒子态显式 Wigner 表述的问题,本文提出计算加速系中 Minkowski-Fock 态特征函数的通用方法,并揭示可通过 Rindler 粒子分布及动量间关联检测加速度。

摘要:

目前尚不存在面向非惯性观察者的 Minkowski 粒子态的显式 Wigner 表述。本文推导了一种通用规则,用于计算加速参考系中 Minkowski-Fock 态的特征函数。对于单粒子态和双粒子态这一特殊情形,该方法能够推导动量空间中粒子数的平均值与关联函数,以及它们受观察者加速度影响的方式。我们表明,就 Rindler 粒子分布而言,Minkowski 单粒子态与双粒子态之间存在不可区分性,这可被视为观察者检测参考系是否具有任何加速度的一种方式。我们发现,对于双粒子态,观察者还能够通过测量具有不同动量的 Rindler 粒子之间的关联来检测加速度。

英文摘要:

An explicit Wigner formulation of Minkowski particle states for non-inertial observers is unknown. Here, we derive a general prescription to compute the characteristic function for Minkowski-Fock states in accelerated frames. For the special case of single-particle and two-particle states, this method enables to derive mean values of particle numbers and correlation function in the momentum space, and the way they are affected by the acceleration of the observer. We show an indistinguishability between Minkowski single-particle and two-particle states in terms of Rindler particle distribution that can be regarded as a way for the observer to detect any acceleration of the frame. We find that for two-particle states the observer is also able to detect acceleration by measuring the correlation between Rindler particles with different momenta.
