黑洞蒸发和孤子物理之间的有趣联系为发现可观察现象开辟了新的道路。由逆散射变换可知，速度是孤子理论中的一个基本参量。考虑到这一点，运动孤子的霍金辐射的研究得到了越来越多的相关性。然而，描述这一现象的理论背景仍然缺乏。在这里，我们采用孤立子几何化技术来研究一维模型中运动孤立子的量子发射。用Sine-Gordon方程的单孤子解表示黑洞，研究了量子化无质量标量场在孤子诱导度规下的Hawking辐射谱。研究了孤子速度与黑洞温度的关系。我们的研究结果解决了在量子引力全景中探测新物理的新方案。
The intriguing connection between black holes’ evaporation and physics of solitons is opening novel roads to finding observable phenomena. It is known from the inverse scattering transform that velocity is a fundamental parameter in solitons theory. Taking this into account, the study of Hawking radiation by a moving soliton gets a growing relevance. However, a theoretical context for the description of this phenomenon is still lacking. Here, we adopt a soliton geometrization technique to study the quantum emission of a moving soliton in a one-dimensional model. Representing a black hole by the one soliton solution of the Sine-Gordon equation, we consider Hawking emission spectra of a quantized massless scalar field on the soliton-induced metric. We study the relation between the soliton velocity and the black hole temperature. Our results address a new scenario in the detection of new physics in the quantum gravity panorama.
