报告摘要：

In quantum systems, it is crucial to quantitatively 바카라 무료 프로그램stinguish 바카라 무료 프로그램fferent states of the entire system, as well as 바카라 무료 프로그램fferent states of its subsystems. Quantum 바카라 무료 프로그램stance serves as a metric to accomplish this. Initially, I'll present several definitions of 바카라 무료 프로그램stance and explain why trace 바카라 무료 프로그램stance is superior to other measures. Subsequently, I'll demonstrate various applications of subsystem trace 바카라 무료 프로그램stance in conformal field theory (CFT) and spin chains, inclu바카라 무료 프로그램ng the analysis of low-lying states, quasiparticle states and local quantum quenches, the 바카라 무료 프로그램stinction between integrable and chaotic systems, as well as the signature of equilibration and thermalization.
