摘要:

近年来,结合精确的量子蒙特卡罗(QMC)方法与现实的核相互作用和一致的电弱电流,特别是那些构建在有效场论(EFT),导致新的见解轻和中等质量的核,中子物质,和电弱反应。这一引人注目的新的工作机构已成为可能的进步,在QMC方法的核物理,这推动了较重的核和非对称核物质的适用性的界限,并通过本地手性EFT相互作用的发展,以次到次到主导的顺序和最低限度的非本地相互作用,包括$Δ$自由度。在这篇综述中,我们讨论了这些最新的发展,并给出了令人兴奋的结果,核,中子物质和中子星,和电弱反应的概述。

英文摘要:

In recent years, the combination of precise quantum Monte Carlo (QMC) methods with realistic nuclear interactions and consistent electroweak currents, in particular those constructed within effective field theories (EFTs), has lead to new insights in light and medium-mass nuclei, neutron matter, and electroweak reactions. This compelling new body of work has been made possible both by advances in QMC methods for nuclear physics, which push the bounds of applicability to heavier nuclei and to asymmetric nuclear matter and by the development of local chiral EFT interactions up to next-to-next-to-leading order and minimally nonlocal interactions including $Δ$ degrees of freedom. In this review, we discuss these recent developments and give an overview of the exciting results for nuclei, neutron matter and neutron stars, and electroweak reactions.
