Illustrating the Electron Topology Using ‘3D Glasses’

Credit: Unsplush.Topological quantum materials are viewed as a promising prospect for energy-efficient electronics and advanced technology in the future. Among their remarkable features is the ability to conduct spin-polarized electrons on their surface, despite being non-conductive in their interior.To better grasp this concept, it's important to understand that spin-polarized electrons possess intrinsic angular momentum,...

Quantum Breakthrough: First-Ever Achievement of a Laughlin State

Credit: Unsplash.The discovery of quantum Hall effects in the 1980s revealed the existence of new forms of matter known as "Laughlin states," named after the American Nobel laureate who successfully characterized them theoretically.These great states manifest uniquely in two-dimensional materials under extremely cold conditions and intense magnetic fields. In a Laughlin state, electrons form an unusual...

Using Gravitational Waves to Hunt for Dark Matter

Credit: Unsplash.A global team of cosmologists has discovered through computer simulations that observing gravitational waves from merging black holes can reveal the real nature of dark matter. Dr. Alex Jenkins of University College London will co-author their discovery today at the 2023 National Astronomy Meeting.The team studied the production of gravitational wave signals in...

A New Method for Managing the Turbulence’s Characteristics

An isolated blob of turbulence is created by the repeated collision of eight vortex rings. (Left) Contained turbulence is illustrated by the breakdown of the blob's energy into the mean flow (yellow) and fluctuating (blue) components. (Right) Inside the chaotic blob, highly erratic tracer particle trajectories are shown. Credit: Matsuzawa et al.According to a...

New Possibilities Found for Room-Temperature Superconductivity

To study superconducting materials in their “normal,” non-superconducting state, scientists usually switch off superconductivity by exposing the material to a magnetic field, left. SLAC scientists discovered that turning off superconductivity with a flash of light, right produces a normal state with very similar fundamental physics that is also unstable and can host brief flashes...

Getting the Best Flavor from Coffee to make Espresso

Coffee. Credit: Portfolio coffee.Espresso coffee is a popular beverage brewed by grinding roasted coffee beans into grains and then forcing hot water at high pressure through a bed of coffee grains to dissolve the soluble content of the coffee and produce espresso. However, recent research has found that more finely ground coffee beans make...

A New Type of Hydropower is Becoming Increasingly Popular

Rocky Mountain pumped-storage hydtroele3ctric power plant is owned by Oglethorpe Power Corp. Source - Thomson200. Public DomainPumped storage hydropower (PSH), a type of hydroelectric energy storage, is rapidly gaining popularity worldwide as a new technology. Unlike the traditional image of hydroelectric power, which is associated with massive dams such as the Hoover Dam or...

A Liquid Laser that is Robust in Air and Tunable by Wind

Credit: NotjungCG/ShutterstockResearchers from the Tsukuba Research Center for Energy Products Science at the University of Tsukuba demonstrated a simple method to create ionic liquid microdroplets that function as flexible, long-lasting, and pneumatically tunable lasers. Unlike existing "droplet lasers" that can not operate under an environment, this new development may enable lasers that could be...
