报告摘要：

In thistalk, we derive a system of Thermodynamic Bethe ansatz (TBA) equationsgoverning the exact WKB periods in one-dimensional Quantum Mechanics witharbitrary polynomial potentials. These equations provide a generalization ofthe ODE/IM correspondence, and can be regarded as the solution of aRiemann-Hilbert problem in resurgent Quantum Mechanics formulated by Voros. Wealso show that our TBA equations, combined with exact quantization conditions,provide a powerful method to solve spectral problems in Quantum Mechanics. Weillustrate our general analysis with a detailed study of cubic oscillators andquartic oscillators. This talk is based on the work with Katsushi Ito andMarcos Marino [arXiv: 1811.04812].
