Atomic Josephson contacts: How Bose-Einstein condensates replicate Shapiro steps

The microscopic processes taking place in superconductors are difficult to observe directly. Researchers at the RPTU University of Kaiserslautern-Landau have therefore implemented a quantum simulation of the Josephson effect: They separated two Bose-Einstein...

Water’s enigmatic surface: X-ray snapshots reveal atoms and molecules at work

Water is all around us, yet its surface layer—home to chemical reactions that shape life on Earth—is surprisingly hard to study. Experiments at SLAC’s X-ray laser are bringing it into focus. Go to Source

Pinpointing the glow of a single atom to advance quantum emitter engineering

Researchers have discovered how to design and place single-photon sources at the atomic scale inside ultrathin 2D materials, lighting the path for future quantum innovations. Go to Source

Dual substitution induces room-temperature ferromagnetism and negative thermal expansion in BiFeO₃

Using a dual-cation substitution approach, researchers at Science Tokyo introduced ferromagnetism into bismuth ferrite, a well-known and promising multiferroic material for next-generation memory technologies. By replacing ions at both the bismuth and iron sites with...

Tiny optical modulator could enable giant future quantum computers

Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair. Go to Source
