AI 中文摘要
我们提出了一种可出现在经典和量子多粒子系统中的独特长程有序相。它由局部破坏序参量对称性子集的杂质和缺陷诱导，即由与复合残余序参量耦合的随机场无序诱导。所提出的“交织”相的特征是在随机场产生的空间交织畴结构背景下的自发对称性破缺。我们通过大规模蒙特卡罗模拟明确证明了在层状\(J_1-J_2\)伊辛磁体中该相的存在。然后我们讨论了在具有电荷和自旋密度波序的系统中的众多潜在应用，包括受挫磁体、铜酸盐和铁基超导体以及超冷原子。
英文摘要
We propose a distinct type of long-range ordered phase that can occur in classical and quantum many-particle systems. It is induced by impurities and defects that locally break a subset of the order-parameter symmetries, i.e., by random-field disorder that couples to a composite vestigial order parameter. The proposed ``implectic'' phase is characterized by spontaneous symmetry breaking on the background of the spatially interwoven domain structure created by the random fields. We explicitly demonstrate the existence of this phase in a layered $J_1-J_2$ Ising magnet by means of large-scale Monte Carlo simulations. We then discuss numerous potential applications in systems featuring charge and spin density wave order including frustrated magnets, cuprate and iron-based superconductors, and ultracold atoms.
