They used a mid-infrared pulse to measure and map out high harmonic generation intensity at temperatures from an extremely low 50 to a moderate 290 Kelvin. <\/p>\n<p>At the low end, the team recorded high-order harmonic generation several hundred times more intense than at room temperature. Photon emissions continued to intensify with increasing gap energy\u2014the energy required for electrons to conduct electricity\u2014along with the drop in temperature. <\/p>\n<p>The team found that such emissions occurred in the Mott-insulating phase of the material, where the strong repulsion between electrons and high gap energy transforms the metal from an electrical conductor to an insulator.<\/p>\n<p>&#8220;We discovered that high-order harmonics in strongly correlated materials highly depend on the gap energy of the materials,&#8221; explains Uchida.<\/p>\n<p>This scaling law can direct theoretical studies towards more refined de<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">script<\/a>ions of non-equilibrium electron dynamics in strongly correlated materials: a central issue in condensed matter physics. <\/p>\n<p>Uchida concludes that their &#8220;findings also provide a foundation for materials design to achieve more efficient nonlinear optical devices.&#8221;<\/p>\n<p>The research was published in <i>Physical Review Letters<\/i>.<\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            Novel quantum sensing possibilities with nonlinear optics of diamonds\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                K.
