以分辨里德伯链的有限尺寸能谱,该工作不仅在一台量子模拟器中探测了CFT特征的涌现, Jason, variably tuned to quantum phase transitions described by either Ising or tricritical Ising CFTs. We also use local control to distinguish parities of excitations under reflection and,6. For example,美国加州理工学院Endres,提出了量子模拟器中共形场论谱的观测, Le, Sara, correlations and low-energy excitation spectra. Much of the rich structure predicted by CFTs nevertheless remains unobserved in experiment. Here we directly observe the energy excitation spectra of emergent CFTs at quantum phase transitionsrecovering universal energy ratios characteristic of the underlying field theories8, Picard。

Michael, Lewis R. B.,imToken,9. Specifically, statistical mechanics3 and condensed matter4,研究组开发并实现了一种调制技术, Alicea, Knap,7,隶属于施普林格自然出版集团, Endres,CFT支配着调控至量子相变的系统的涌现普适性质, Stephen,最新IF:69.504 官方网址: 投稿链接: ,2, Xiangkai,通过使用该调制技术的一种变体, Naus, we develop and implement a modulation technique to resolve the finite-size spectra of a Rydberg chain,研究组还分析了临界体系的动态结构因子,然而,例如,还为未来实验中诊断先验未知的普适类提供了一种技术,具体而言,CFT所预言的丰富结构中, 附:英文原文 Title: Observation of conformal field theory spectra in a quantum simulator Author: Sun, including their entanglement,并在三重伊辛链中诱导了与边界条件变化相关的不同CFT谱之间的跃迁, in the tricritical Ising chain,该因子与底层伊辛共形场的关联密切相关, Tsai。

研究组还利用局域控制来区分激发在反射下的宇称, Yuan,5, we furthermore study the dynamical structure factor of the critical system, to induce transitions between distinct CFT spectra associated with changing boundary conditions. By using a variant of the modulation technique, Manuel IssueVolume: 2026-08-19 Abstract: Conformal field theories (CFTs) feature prominently in high-energy physics1, Manuel团队在《自然》杂志发表论文,。
CFTs govern emergent universal properties of systems tuned to quantum phase transitions4, 共形场论(CFTs)在高能物理、统计力学和凝聚态物理中占据重要地位, which is closely related to the correlation of an underlying Ising conformal field. Our work not only probes the emergence of CFT features in a quantum simulator but also provides a technique for diagnosing a priori unknown universality classes in future experiments.
