Atomic interactions in everyday solids and liquids are so complex that some of these materials’ properties continue to elude physicists’ understanding. Solving the problems mathematically is beyond ...

Feb. 23 (UPI) --Scientists in Spain have developed a new material, a so-called hyperbolic metasurface, that inverts light waves. The technology could give researchers more precise control of optical ...

Mathematica Scandinavica, Vol. 111, No. 2 (2012), pp. 187-209 (23 pages) We study area-stationary surfaces in the space L(H3) of oriented geodesics of hyperbolic 3-space, endowed with the canonical ...
