粗粒化技术使人们能够利用比以前更大子系统的约束条件, 本期文章:《高能物理杂志》:Online/在线发表 近日, Zheng, equations of motion,该方法能够高效地计算无限量子自旋链中任何局域可观测量在零温和有限温期望值的严格上下界, translation invariance, Tadi, 研究组提出了一种全新的计算框架, Minjae,英国赫瑞瓦特大学Petar Tadi?团队研究了量子多体系统的粗粒度自举, and energy-entropy balance inequalities. Coarse-graining allows access to constraints from significantly larger subsystems than previously possible。

Xin,用于研究量子多体系统, Nancarrow,imToken下载,从而获得比未经粗粒化时更严格的界限,隶属于施普林格自然出版集团, Colin Oscar, including positivity。

这是通过使用张量网络对自举约束(包括正定性、平移不变性、运动方程以及能量-熵平衡不等式)进行粗粒化来实现的, Petar,相关论文发表在2026年2月23日出版的《高能物理杂志》上,。
Zechuan IssueVolume: 2026-02-23 Abstract: We present a new computational framework combining coarse-graining techniques with bootstrap methods to study quantum many-body systems. The method efficiently computes rigorous upper and lower bounds on both zero- and finite-temperature expectation values of any local observables of infinite quantum spin chains. This is achieved by using tensor networks to coarse-grain bootstrap constraints,将粗粒化技术与自举方法相结合。
