量子猝灭中的新旧标度律
Old and New Scaling Laws in Quantum Quench
摘要：
多体系统对通过或接近临界点的时变耦合的响应表现出普遍的标度行为。在某些情况下，自20世纪70年代以来，标度定律就已为人所知。最近全息技术已被用来了解这种缩放的起源。在此过程中，在全息模型中发现了其他区域的新标度行为，这些行为后来被证明在一般的场论中成立，而与全息无关。这一贡献总结了最近的工作，这些不同的缩放制度。
英文摘要：
The response of a many body system to a time dependent coupling which passes through or approaches a critical point displays universal scaling behavior. In some regimes, scaling laws have been known since the 1970's. Recently holographic techniques have been used to understand the origins of such scaling. Along the way, new scaling behaviors in other regimes have been found in holographic models, which have later been shown to hold in a generic field theory regardless of holography. This contribution summarizes recent work on these various scaling regimes.
