They can be bent after all. In defiance of a decades-old assumption, gamma-rays can be focused with lenses. This has been shown in experiments led by the physicist Professor Dieter Habs of LMU Munich. The discovery opens up a range of potential applications – from monitoring of nuclear waste to new cancer therapies.

In principle, so-called "quantum simulators" should permit investigations of complex physical processes that are not amenable to classical approaches. Now LMU researchers have provided an experimental demonstration of the superiority of such systems over their classical counterparts.

An international team, led by LMU physicist Tim Liedl, has used “molecular origami” to produce a novel class of materials capable of modulating the properties of light in predictable ways. Based on DNA-bound gold particles, these structures could lead to the construction of unconventional lens systems.
