Unravelling a photoinduced compressive lattice response in the canonical Mott...

This proposal aims at determining the nature of lattice strain, compressive vs tensile, following the ultrafast photoexcitation of hot carriers in the canonical Mott insulator...本研究提案旨在明确典型莫特绝缘体（Mott insulator）中热载流子经超快光激发后所诱导的晶格应变的属性，即判定其为压应变还是拉应变。
