Physicists Generate New Nanoscale Spin Waves

Illustration of the experiment. Credit: Dreyer et al, Nature Communications (CC-BY-SA 4.0)Strong alternating magnetic fields can be utilized to generate a new kind of spin wave that was previously just theoretically anticipated. A team of physicists from Martin Luther College Halle-Wittenberg (MLU) achieved this for the first time. They report on their work in...

SU(N) Matter Is About Three Billion Times Colder Than Deep Space

An artist’s conception of the complex magnetic correlations physicists have observed with a groundbreaking quantum simulator at Kyoto University that uses ytterbium atoms about 3 billion times colder than deep space. Different colors represent the six possible spin states of each atom. The simulator uses up to 300,000 atoms, allowing physicists to directly observe...

Building a “Quantum Heat Pump” To Search For Elusive Dark Matter

Scientists have developed a heat pump that uses light particles on a quantum range. Scientists can currently measure radio frequency signals closer to the quantum limit. Professionals say this technique works in searching for dark matter, a component of the universe whose existence is discernible primarily by its gravitational attraction. 30.1 percent of the...

A Particle New To Physics Could Solve the Dark Matter Mystery

Anomalies in nuclear physics experiments may show signs of a new force.A team of scientists in Hungary currently published a paper that hints at the presence of a previously unknown subatomic particle. The group first reported finding traces of the particle in 2016, and they now report more traces in a different experiment.If the...

Physicists Confirm the Existence Of Two-Dimensional Particles Called ‘Anyons’

After decades of exploration in nature's most minor domains, physicists have finally found proof that anyons exist. 1st predicted by theorists in the early 1980s, these particle-like objects arise in realms confined to two dimensions and then under certain circumstances-- like at temperatures near absolute zero and in the existence of a solid magnetic...
