In a paper recently published in Nature Communications, researchers from the Paul-Drude-Institut in Berlin, and the Instituto Balseiro in Argentina, demonstrated that the mixing of confined quantum fluids of light and GHz sound leads to the emergence of an elusive quasi-particle: the phonoriton. This discovery opens a novel way to coherently convert information between optical and microwave domains, bringing potential benefits to photonics, optomechanics, and optical communication technologies.

In a paper published today in Nature Communications, researchers from the Paul Drude Institute in Berlin, Germany, and the Instituto Balseiro, Bariloche, Argentina, demonstrated that light emitters with different resonance frequencies can asynchronously self-lock their relative energies by exchanging mechanical energy. This finding paves the way for increased control of light sources and GHz-to-THz interconversion relevant to quantum technology.

Scalable quantum networks require on-chip transfer and manipulation of single particles as well as their interconversion to single photons for long-range information exchange.

Researchers from the Paul-Drude-Institut in Berlin, the Helmholtz-Zentrum in Dresden and the Ioffe Institute in St. Petersburg have demonstrated the use of elastic vibrations to manipulate the spin states of optically active color centers in SiC at room temperature.

Prof. Dr. Henning Riechert is awarded the prestigious Welker-Award during Compound Semiconductor Week 2020.

Strengthening Berlin as an international science metropolis is the aim of a joint initiative by the capital's non-university research institutions. They have joined forces to form BR 50 (Berlin Research 50) in order to jointly develop strategies for research and exchange with politics and society in the future. This facilitates and strengthens cooperation with the Berlin universities.

An international collaboration involving European, Israeli, and US scientists realize for the first time strong and directionally dependent interactions in quantum liquids of excitons, which contrasts with the spatial isotropy of the coupling between charged particles. This spatial anisotropy affects the way particles arrange themselves in space and opens routes to artificially created exotic states of matter. The results were published in Physical Review X.

Noise is often an undesirable phenomenon, for example a recorded conversation in a noisy room, astronomical observations with large background signals or in image processing. A research team from China, Spain, and Germany has demonstrated that noise can induce spatial and temporal order in nonlinear systems. This effect may be used in the future to identify signals that are hidden in a large amount of noise. Inversely, signals may be embedded in a noisy background and thereby be ciphered in order to recover them later.

Semiconducting oxides form a new and highly regarded class of materials in semiconductor technology. Gallium oxide is the typical material for it, promising previously unattainable electronic devices with extreme high-voltage strength and optical transparency in the deep ultraviolet spectral range. Now, for the first time, scientists at the Paul Drude Institute for Solid State Electronics (PDI) have succeeded in dramatically increasing the yield of gallium oxide crystal growth using a catalytic effect.

From November 1 to 5, 2017, the Paul Drude Institute (PDI) for Solid State Electronics will host an interactive pop-up exhibition on the world of quantum mechanics. The exhibition is presented by the IQC (Institute for Quantum Computing) of the University of Waterloo with support from the Canadian Embassy. The Berlin physicists of the host institute will complement the exhibition with The Quantum Lab featuring exhibits on their current research. PDI wants to give Berlin Science Week visitors a unique experience of complex matter.
