标题： Integral method for the calculation of Hawking radiation in dispersive media II. Asymmetric asymptotics

摘要： 模拟引力实验使得在实验室环境中实现黑洞时空并观测验证霍金辐射成为可能。 由于这类模拟系统通常受色散主导，因此需要在强色散情况下计算预测的霍金谱的有效技术。 在之前的论文中，提出了一种傅里叶空间中的积分方法，用于渐近对称的静态$1+1$-维背景。 在这里，该方法被推广到散射区域左右的渐近区域不同的背景。 显示英文摘要

摘要： Analogue gravity experiments make feasible the realisation of black hole spacetimes in a laboratory setting and the observational verification of Hawking radiation. Since such analogue systems are typically dominated by dispersion, efficient techniques for calculating the predicted Hawking spectrum in the presence of strong dispersion are required. In the preceding paper, an integral method in Fourier space is proposed for stationary $1+1$-dimensional backgrounds which are asymptotically symmetric. Here, this method is generalised to backgrounds which are different in the asymptotic regions to the left and right of the scattering region.
