UConn Physics Colloquium
From Negative Refraction to Single Photon Control: New Frontiers of Quantum Optics
UConn Physics Department
Quantum coherence effects such as electromagnetically induced transparency can be used for a multitude of linear and nonlinear optics. I will introduce two novel applications: First, negative refraction with the potential development of the "superlens" as an example for a linear effect, and second, single-photon nonlinearities such as might be used, for example, for quantum computing.
Starting with a simple model, I will explain the basic ideas of quantum coherence effects, i.e., the manipulation of matter by coherent light. I will use two examples to demonstrate potential uses of these ideas: First, how can one utilize the long-range interaction of dipolar molecules to create a quantum computer? Second, how to electromagnetically induce chirality and how to use it to create media with negative refraction, as needed, for example, for the so-called "superlens"?
