引导氘核
Bootstrapping the deuteron
摘要：
Bootstrap是量子物理学的一个新颖而雄心勃勃的范例。它的目的是利用一般物理原理和自洽条件的理论约束来解决目标问题。自助哲学可以追溯到20世纪60年代。它的真正力量直到最近才被认识到，例如，共形场论和相对论性散射振幅。受[X]启发汉，S. A. Hartnoll，and J. Kampleoff，Phys. Rev. Lett. 125，041601（2020）]，我们报告了低能核物理中的第一个自举结果，其中氘核，其哈密顿量由谐振子空间中的无π有效场论给出，通过直接利用最基本的量子力学要求来解决，即概率永远不会为负。我们的研究表明，引导方法可以帮助研究现实的核系统。
英文摘要：
Bootstrap is a novel and ambitious paradigm for quantum physics. It aims to solve the target problems by exploiting theoretical constraints from general physical principles and self-consistency conditions. The bootstrap philosophy dates back to the 1960s. Its real power has been recognized only recently in, e.g., conformal field theories and relativistic scattering amplitudes. Inspired by [X. Han, S. A. Hartnoll, and J. Kruthoff, Phys. Rev. Lett. 125, 041601 (2020)], we report the first bootstrap results in low-energy nuclear physics, where deuteron, with its Hamiltonian given by pionless effective field theory in harmonic oscillator space, is solved by directly exploiting the most fundamental quantum mechanical requirement that probability should never be negative. Our study shows that the bootstrap method can be helpful in studying realistic nuclear systems.
