New method of characterizing Graphene

Scientists have developed a new method of characterizing graphene’s properties without applying disruptive electrical contacts, allowing them to investigate both the resistance and quantum capacitance of graphene and other two-dimensional materials. Researchers from the Swiss Nanoscience Institute and the University of Basel’s Department of Physics reported their findings in the journal Physical Review Applied.

Design of a fully connected quantum optimizer

A team of theoretical physicists at the University of Basel in Switzerland, has found a way to design a fully connected quantum optimizer -- a machine that holds the promise to speed up the solution of hard optimization problems -- by taking advantage of a fundamental property of the superconducting state of matter. In a further vital step towards building a quantum optimizer able to solve real world problems, they also show that this new architecture is more robust to noise than existing alternatives. Their work has been published in Science Advances.

Rare Earths become water-repellent only as they age

Surfaces that have been coated with rare earth oxides develop water-repelling properties only after contact with air. Even at room temperature, chemical reactions begin with hydrocarbons in the air. In the journal Scientific Reports, researchers from the University of Basel, the Swiss Nanoscience Institute and the Paul Scherrer Institute report that it is these reactions that are responsible for the hydrophobic effect.

Gravitational wave factories in the early universe

Researchers from the Particles & Cosmology group at the Department of Physics have found that in the early universe after inflation, so-called oscillons can act as "gravitational wave factories" and produce much more gravitational waves than previously thought. Oscillons are localized and strong scalar field fluctuations that are comparatively long-lived. Numerical simulations showed that the produced gravitational waves have a specific frequency, related to the underlying theory of the early universe, and manifest themselves as a pronounced peak in the otherwise rather broad spectrum of gravitational waves from early universe dynamics. If this peak is in the right frequency range, the effects from the oscillons can be observed by the running or planned gravitational wave detectors, e.g. by the aLIGO-AdVirgo detector network. The detection of such a gravitational wave signal would provide a fascinating window into the physics of the early universe. The results are published in Physical Review Letters

Daniel Loss Receives the King Faisal International Prize

Professor Daniel Loss from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute has been awarded the King Faisal International Prize for Science 2017. The King Faisal Foundation awarded Loss the renowned science prize for his discovery of a concept for development of a quantum computer based on the intrinsic angular momentum of electrons. Loss has further refined his theory over recent years and established a completely new field of research.
