综述: 周期系统中的强场现象

Rev. Mod. Phys. 90, 021002 (2018) - Colloquium: Strong-field phenomena in periodic systems (aps.org)

摘要:

ABSTRACT

The advent of visible-infrared laser pulses carrying a substantial fraction of their energy in a single field oscillation cycle has opened a new era in the experimental investigation of ultrafast processes in semiconductors and dielectrics (bulk as well as nanostructured), motivated by the quest for the ultimate frontiers of electron-based signal metrology and processing. Exploring ways to approach those frontiers requires insight into the physics underlying the interaction of strong high-frequency (optical) fields with electrons moving in periodic potentials. This Colloquium aims at providing this insight. Introduction to the foundations of strong-field phenomena defines and compares regimes of field-matter interaction in periodic systems, including (perfect) crystals as well as optical and semiconductor superlattices, followed by a review of recent experimental advances in the study of strong-field dynamics in crystals and nanostructures. Avenues toward measuring and controlling electronic processes up to petahertz frequencies are discussed.

在单个场振荡周期中携带大部分能量的可见红外激光脉冲的出现开启了半导体和电介质(块体和纳米结构)中超快过程的实验研究的新时代,其动机是寻求基于电子的信号计量和处理的终极前沿。探索接近这些前沿的方法需要深入了解强高频(光学)场与电子在周期性电位中移动的相互作用背后的物理学。本次座谈会旨在提供这一见解。强场现象基础介绍定义和比较了周期性系统中场物质相互作用的机制,包括(完美)晶体以及光学和半导体超晶格,然后回顾了强场研究的最新实验进展晶体和纳米结构的动力学。讨论了测量和控制高达拍赫兹频率的电子过程的途径。
