Recent work has demonstrated sub-diffraction limited focusing using time-reversal mirrors and sources in scattering media at--microwave frequencies. We numerically investigate the possibility of observing analogous effects ...

Recently, quantum adiabatic computation has attracted more and more attention in the literature. It is a novel quantum computation model based on adiabatic approximation, and the analysis of a quantum adiabatic algorithm ...

We present detailed experimental and numerical studies of random lasing in weakly scattering systems. The interference of scattered light. which is weak in the passive systems, is greatly enhanced in the presence of ...

We show that Mach-Zehnder interferometers (MZIs) formed from waveguides in a perfectly reflecting cladding can display manifestly different transmission characteristics to conventional MZIs due to mode recirculation and ...

The goal of this paper is to compare strategies for reducing partial volume effects by either minimizing the cause (i.e. improving resolution) or correcting the effect. Correction for resolution loss can be achieved either ...

We show that in some cases, catalyst-assisted entanglement transformation cannot be implemented by multiple-copy transformation for pure states. This fact, together with the result we obtained in R. Y. Duan, Y. Feng, X. ...

We describe a method for accurate calculation of the Relative Local Density of States (RLDOS) as a function of frequency and position in finite sets of coated cylinders. The RLDOS is important, since it describes the ...

Alternative materials are required to enhance the efficacy of plasmonic devices. We discuss the optical properties of a number of alloys, doped metals, intermetallics, silicides, metallic glasses and high pressure materials. ...

A simple room-temperature solution chemical route for bulk synthesis of high quality ?- Bi2O3 nanowires has been demonstrated. The nanowires have a diameter of about 50 nm and a length in the range of several to tens of ...
