When atoms are optically coupled to a one dimensional waveguide, they can interact through macroscopic distances. The retardation effects inherent to field propagation and the associated delay in information backflow between the atoms result in a departure from the familiar Markovian dynamics. We study the case of two two level atoms coupled along a waveguide. One remarkable feature of the dynamics in this regime is the formation of long-lived bound states in the continuum (BIC),30 that refer to a hybrid diatomic molecule bound together by propagating modes of a field. In particular, we study the probability of reaching such a bound states of the system starting in an initially anti-symmetric state of the emitters.
In this paper we present theory and simulations of an optical spring mirror with emphasis on the incident laser
beam configuration and the associated optical trapping forces. We elucidate the physical mechanisms underlying the
optical trapping using the example of an incident Gaussian beam and demonstrate that guided-wave trapping shows
particular promise for stable trapping in both the translational and rotational degrees of freedom.
The National Optical Astronomy Observatory, Science Foundation Arizona, and the University of Arizona are teamed
on a long-term multi-pronged approach to photonics education in Arizona that is congruent with a "green" future. This
approach involves education around the content areas of renewable energy sources, laser-based communication and
laser-assisted manufacturing, photovoltaics, solid-state lighting and displays, nanotechnology, and other recent
technology developments. Equally important is the process by which we are working to transform the Arizona K-12
schools and universities through programs that emphasize
problem-solving, system thinking, and collaborative
approaches. We also emphasize the role of the informal education system (such as museums) and the value of "freechoice"
learning to science education. A key to our success is the work of traditionally research-oriented organizations
and industry associations in supporting science and technology education.
We review an extension of the optical coherence theory to the case of atomic Schrodinger waves, and show that this requires the introduction of several classes of coherence. Optical methods to manipulate the coherence of matter-wave fields are discussed.
We propose a new direct overwrite scheme that requires no initialization field. The scheme uses a preformated reference layer to assist on writing and erasure.
