The research team led by Dr. Gerard Verbiest and JARA-FIT scientist Prof. Christoph Stampfer at the Physics Department at the RWTH Aachen University, discovered a new possibility for ultrasound detection. The physicists fabricated a graphene resonator on a silicon substrate in a way that the device could be mounted onto an ultrasound transducer.
The meteorite Bishunpur, which fell to Earth in 1895 in the Indian Indian state of Uttar Pradesh, could shed light on the magnetism at the beginning of the universe. In order to unravel the secrets of the meteorite, scientists at Research Centre Jülich, together with experts from England and Norway, have investigated the material using electron holography.
Scientists JARA have discovered a phenomenon similar to the laser effect with which the structure of organic molecules can be examined at previously unmatched levels of precision. In contrast to a laser, this "raser" (radiowave amplification by stimulated emission of radiation) is pumped with parahydrogen and does not operate at light frequencies, instead oscillating continuously at various radio frequencies of around 100 kHz. A precise fingerprint of the molecular structure can thus be obtained.
The QuTech institute in Delft as well as Forschungszentrum Jülich and RWTH Aachen University, both partners of the Aachen Jülich Research Alliance (JARA), have intensified their collaboration through an official agreement.
Quantum computers are viewed as ultrafast computers of the future. The Scalable Solid State Quantum Computing project aims to establish the conditions for future multi-qubit systems. In order to realize such systems with several hundred qubits, new technologies are required so that the qubits can be precisely controlled. Forschungszentrum Jülich, RWTH Aachen University, and the Karlsruhe Institute of Technology are all involved in the project, which is being provided with € 6 million in funding by the Helmholtz Association.
Utilizing the magnetic moment (spin) of an electron leads to a faster and more energy efficient processing of bits and bytes than within the actual Si-based processors. So far, manipulation experiments of the spin revealed signals which are much too small for any practical application. A possible reason for the unfavorable efficiency has now...
In “Magnetic Skyrmions for Future Nanospintronic Devices”, or “MAGicSky” for short, scientists from France, Germany, Great Britain and Switzerland are pursuing an innovative concept for novel computer components based on magnetic vortices known as skyrmions.
The overheating of computer chips is a major obstacle to the development of faster and more efficient computers and mobile phones. One promising remedy for this problem could be a class of materials first discovered just a few years ago: topological insulators.
