Scientists have created a nano-electronic circuit which vibrates without any external force. Just as a guitar string vibrates when plucked, the wire — 100,000 times thinner than a guitar string — vibrates when forced into motion by an oscillating voltage. The surprise came when they repeated the experiment without the forcing voltage. Under the right […]
From electrons to photons. From photons to electrons…
The quantum computer of the future will be able to carry out computations far beyond the capacity of today’s computers. Quantum superpositions and entanglement of quantum bits (qubits) make it possible to perform parallel computations. Making useful computations requires large numbers of qubits and it is this upscaling to large numbers that is providing a […]
Light speed. Less than 1000 m/s.
Researchers at TU Wien were the first to successfully detect Weyl particles in strongly correlated electron systems – that is, materials where the electrons have a strong interaction with each other. In materials like this, the Weyl particles move extremely slowly, despite having no mass. “The strong interactions in such materials usually lead, via the […]
In a world full of possibilities… how can anything NOT be possible?
Negative mass. Impossibilities. Dasein.
Matter with negative mass, a seeming impossibility, could actually have existed in the early universe, a new study shows. A novel solution to Einstein’s equations for gravity permits the existence of negative mass in a rapidly expanding universe like our own, physicists Manu Paranjape and Saoussen Mbarek of the University of Montreal report November 14 […]
