The Li group explores the fascinating world of light-matter interactions in quantum materials and devices. We dive into fundamental questions that shape the future: How small can the building blocks of information storage be? How can we transmit data using the faintest traces of light, like single or entangled photons? How fast can we manipulate electrons at the smallest scales?

At the intersection of the ultrafast and the ultrasmall, our group is uncovering new scientific frontiers and developing technologies that could redefine the limits of speed, efficiency, and scale in the quantum realm. We enjoy collaborations with many leading scientists both at UT and elsewhere. We are proud to be part of the following organizations.
