引力坍缩成黑洞已经被广泛研究与经典来源。我们发展了一种新的形式来模拟量子场形成黑洞。通过选择一个方便的相干态,这种形式主义利用了用于经典坍缩的成熟技术,并增加了量子场算符模函数的演化。发散与宇宙常数和Pauli-Villars领域正规化。以无质量球对称标量场为例,通过再现引力坍缩中的经典结果,并指出量子效应引起的差异,证明了该方法的有效性.我们还发现临界坍缩中的Choptuik标度在半经典模拟中仍然存在,而且当系统接近临界点时,与经典Choptuik标度的量子偏离减小.
Gravitational collapse into a black hole has been extensively studied with classical sources. We develop a new formalism to simulate quantum fields forming a black hole. By choosing a convenient coherent state, this formalism taps into well-established techniques used for classical collapse and adds on the evolution of the mode functions of the quantum field operator. Divergences are regularized with the cosmological constant and Pauli-Villars fields. Using a massless spherically symmetric scalar field as an example, we demonstrate the effectiveness of the formalism by reproducing some classical results in gravitational collapse, and identifying the difference due to the quantum effects. We also find that Choptuik scaling in critical collapse survives in the semiclassical simulation, and furthermore the quantum deviation from the classical Choptuik scaling decreases when the system approaches the critical point.
