A team at UPV’s Nanophotonics Technology Center has discovered a new fundamental symmetry in electromagnetism, acoustics and elasticity laws: a temporal supersymmetry.

According to Carlos García Meca and Andrés Macho Ortiz, researchers at NTC-UPV, this new symmetry allows the conservation of the linear moment between dramatically different physical systems. This paves the way to designing pioneering optical, acoustic and elastic devices, including invisible omnidirectional, polarization-independent materials, ultra-compact frequency shifters, isolators and pulse-shape transformers.

“These devices allow us to unusually modify different properties of light signals inside photonic circuits to process the spread of information. This is vital in communication systems. Moreover, we can adapt the functionality of those devices to the requirements at any time, as they are dynamically configurable,” explained Carlos García Meca.
