Imaging by flat lens using negative refraction
The positive refractive index of conventional optical lenses means that they need curved surfaces to form an image, whereas a negative index of refraction allows a flat slab of a material to behave as a lens a...

Density of the Fisher Zeroes for the Ising Model
The density of the Fisher zeroes, or zeroes of the partition function in the complex temperature plane, is determined for the Ising model in zero field as well as in a pure imaginary field iπ/2. Results are gi...
