Quantum Coherence in Low-Dimensional Systems
In this talk, I will summarize the research activities of our group here at Texas Tech. These efforts focus on the study of quantum coherent phenomena in low-dimensional many-body systems. The possibility of probing or even controlling such systems using cavity-QED technology has attracted a great deal of recent attention. We have recently completed a comprehensive study of the one-dimensional electron gas and the Tomonaga-Luttinger liquid in this context. Notably, we find that these systems can exhibit superradiance, a quantum coherent effect in which the emission of light generates entanglement, which leads to an 'acceleration' in the rate light is emitted. This is significant as it points to a way of generating and measuring quantum entanglement in many-body systems. Our group also has a strong interest in engineered quantum systems, and I will describe recent work on superconducting circuits and quantum annealers. I will also highlight our group's extensive collaborations, involving researchers bother here at Texas Tech and at other institutions. For example, we are partnering with the University of Utah and Oregon State on recent experiments involving transport through short, high-quality carbon nanotubes. Theory work done by our group has shed light on quantum coherent phenomena seen in these experiments.
