Quantum materials


Quantum materials is a broad term in condensed matter physics, to put under the same umbrella, materials that present strong electronic correlations and/or some type of electronic order, or materials whose electronic properties are linked to non-generic quantum effects, such as topological insulators, Dirac electron systems such as graphene, as well as systems whose collective properties are governed by genuinely quantum behavior, such as ultra-cold atoms, cold excitons, polaritons, and so forth. A common thread in the study of quantum materials is the concept of emergence..

History

In 2012, Joseph Orenstein published an article in Physics Today about "ultrafast spectroscopy of quantum materials". Orenstein stated, As a paradigmatic example, Orenstein refers to the breakdown of Landau Fermi liquid theory due to strong correlations. The use of the term "quantum materials" has been extended and applied to other systems, such as topological insulators, and Dirac electron materials. The term has gained momentum since the article "The rise of quantum materials" was published in Nature Physics in 2016. Quoting:
