商品描述
This book studies the dynamics of fundamental collective excitations in quantum materials, focusing on the use of state-of-the-art ultrafast broadband optical spectroscopy. Collective behaviour in solids lies at the origin of several cooperative phenomena that can lead to profound transformations, instabilities and phase transitions. Revealing the dynamics of collective excitations is a topic of pivotal importance in contemporary condensed matter physics, as it provides information on the strength and spatial distribution of interactions and correlation.
The experimental framework explored in this book relies on setting a material out-of-equilibrium by an ultrashort laser pulse and monitoring the photo-induced changes in its optical properties over a broad spectral region in the visible or deep-ultraviolet. Collective excitations (e.g. plasmons, excitons, phonons...) emerge either in the frequency domain as spectral features across the probed range, or in the time domain as coherent modes triggered by the pump pulse. Mapping the temporal evolution of these collective excitations provides access to the hierarchy of low-energy phenomena occurring in the solid during its path towards thermodynamic equilibrium. This methodology is used to investigate a number of strongly interacting and correlated materials with an increasing degree of internal complexity beyond conventional band theory.商品描述(中文翻譯)
本書研究量子材料中基本集體激發的動力學，重點在於使用最先進的超快寬頻光譜技術。固體中的集體行為是多種協同現象的根源，這些現象可能導致深刻的轉變、不穩定性和相變化。揭示集體激發的動力學是當代凝聚態物理學中一個至關重要的主題，因為它提供了有關相互作用和相關性強度及空間分佈的信息。
本書探討的實驗框架依賴於通過超短激光脈衝使材料處於非平衡狀態，並監測其在可見光或深紫外範圍內的光學性質的光激變化。集體激發（例如，等離子體子、激子、聲子等）要麼在頻率域中以探測範圍內的光譜特徵出現，要麼在時間域中作為由泵浦脈衝觸發的相干模式出現。映射這些集體激發的時間演變提供了訪問固體在其向熱力學平衡過程中發生的低能現象層次結構的途徑。這種方法論用於研究一系列強相互作用和相關材料，這些材料在內部複雜性上超越了傳統的能帶理論。
