The world´s lightest mirror

Physicists at the MPQ have engineered the lightest optical mirror imaginable. The novel metamaterial is made of a single structured layer consisting only of a few hundred identical atoms arranged in the two dimensional array […]

Driven Topology

An international team of physicists from the Ludwig-Maximilians Universität (LMU) and the Max Planck Institute of Quantum Optics together with collaborators from the University of Cambridge, TU Berlin and the Université Libre de Bruxelles succeeded […]

Playing Pool with Excitons

Semiconductors play an important role, be it in electronics, optoelectronics or photovoltaics. But like other solid bodies, they are quantum many-body systems. Therefore, a calculation of their material properties would overburden conventional computers. Instead, this […]

Quantum Brakes in Molecules

Physicists of the Laboratory for Attosecond Physics have measured the flight times of electrons in molecules after their creation with light. The small quantum particles were emitted from a specific atom within the molecules, which […]

Long-lived pionic helium

MPQ Scientists opened a new window into the quantum world. After eight years they succeeded in a challenging experiment with PSI and CERN: they created an artificial atom, the so-called pionic helium, in which the […]
