摘要
矩阵-产品态方法原子核中的粒子会形成相互作用的粒子对，这与在超导体中观察到的库珀粒子对如出一辙。传统上，人们使用巴丁、库珀和施里弗（BCS）首创的均场技术来分析这些粒子对。然而，最初为凝聚态物理学中的一维自旋链而开发的矩阵-积态（MPS）方法则带来了重大进步。这种方法可以通过简单和更广义的配对哈密顿来精确计算核特性，消除了与均场近似通常相关的假象。更多详情，请参阅 Roman Rausch 及其合作者的 2300436 号文章。
The atomic nucleus contains particles that form interacting pairs, mirroring the Cooper pairs observed in superconductors. These pairs are traditionally analyzed using the mean-field technique pioneered by Bardeen, Cooper, and Schrieffer (BCS). However, the matrix-product state (MPS) approach, originally developed for one-dimensional spin chains in condensed-matter physics, offers a significant advancement. This method enables the precise computation of nuclear properties from both simple and more generalized pairing Hamiltonians, eliminating the artifacts commonly associated with mean-field approximations. For further details, see article number 2300436 by Roman Rausch and co-workers.
期刊介绍：
Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
