Cavity Quantum Electrodynamic Control of Condensed Matter (Research Topic Area - 1aii(1))
Abstract
Recently, various solid-state cavity quantum electrodynamics systems have emerged, opening up exciting new opportunities for studying the interaction of quantized light with quantum many-body systems. Cooperative enhancement of light-matter coupling, combined with colossal dipole moments in solids, is promising for entering uncharted regimes of ultrastrong coupling (USC). Here, based on recent developments made in the PIÕs group in the preparation of materials placed inside high quality-factor (Q) terahertz (THz) cavities, the objective of the proposed new research is to provide insight into the ground-state properties of strongly correlated materials ultrastrongly coupled with vacuum electromagnetic fields in a high-Q THz cavity. The ultimate goal of this research is to realize, analyze, and control the spontaneous appearance of ordered phases of field-matter hybridized states. Such phenomena can also be utilized for constructing unique protocols for ultrafast gates and ultrasecure state preparation for quantum information processing. Specifically, the proposed research will be built upon the PIÕs expertise in high-Q THz cavities and driven by recent theoretical proposals for manipulating material properties with quantum light. The material systems to study will include semiconductors quantum Hall systems (GaAs and AlAs), quasi-two-dimensional BCS (Pb) and high-Tc (YBCO) superconductors, Kondo insulators, and graphene. The proposed experiments will probe the nature of the ground state of lightmatter- coupled systems, using state-of-the-art THz spectroscopy at low temperatures and high magnetic fields. Overall, our high- Q THz cavities will provide novel ways to manipulate the ground state of matter by quantum light in equilibrium, in contrast to nonequilibrium phenomena typically found in laser-driven condensed matter systems. Achieving the above-stated goals will not only advance our understanding of light-matter interaction phenomena in solids but also open up possibilities for new ways to control material properties. Therefore, these studies can lead to next-generation solid-state devices that exploit novel properties achieved through interaction with cavity light to potentially impact DODÕs capabilities, including surveillance and target acquisition; command, control, and communications; electronic warfare; and reconnaissance.
