Using Supercurrent Measurements to Identify True Topological Majoranas

Uppsala University physicists have used supercurrent measurements to identify ways to differentiate between true and “fake” Majorana states in one of the experimental setups used most often.

Magnon Drag in Paramagnetic Materials Could Boost Thermoelectric Efficiency

An international research team has found that local thermal perturbations of spins in a solid have the ability to transform heat to energy even in a paramagnetic material, where spins were not considered to correlate sufficiently long to do so.

New Technique Uses Organic Molecules to Fabricate Novel Spintronic Devices

Physicists have developed a new technique for the fabrication of unique types of electronic components called spintronic devices. Since the future of such low-power, high-performance devices looks promising, efficient means to develop them are highly in demand.

Scientists Detect the Ringing of a Newborn Black Hole for the First Time

If Albert Einstein’s theory of general relativity holds true, then a black hole, born from the cosmically quaking collisions of two massive black holes, should itself “ring” in the aftermath, producing gravitational waves much like a struck bell reverbates sound waves.

Researchers Perform Experiments to Build an Atomic Nuclear Clock

Building the most precise clock in the world requires something that “ticks” extremely fast and extremely accurate. Electrons used in the case of an atomic clock can be switched back and forth between two distinct states in a way that is defined very precisely.

Curtin Research Reveals tsunami Followed Dinosaur-killing Asteroid

Curtin University researchers who were part of a scientific expedition that retrieved core samples from a crater in the Gulf of Mexico have found evidence that the asteroid that caused the mass extinction of the dinosaurs also triggered a giant tsunami.

Deciphering the Surface Electronic Structure of Topological Insulators

Some materials, such as copper, are good conductors of electricity. However other materials, such as glass, are poor conductors. A specific type of material, known as a topological insulator, behaves as a conductor at its surface and as an insulator in its interior.
