Quantum state lifetimes extended by laser-triggered electron tunneling in cuprate ladders
on June 5, 2025 at 5:08 pm
Quantum materials exhibit remarkable emergent properties when they are excited by external sources. However, these excited states decay rapidly once the excitation is removed, limiting their practical applications.

Physicists observe a new form of magnetism for the first time
on June 5, 2025 at 1:12 pm
MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry “spintronic” memory chips.

Physicists figure out how an electric field can switch off superconductivity
on June 5, 2025 at 12:38 pm
Transistors are fundamental to microchips and modern electronics. Invented by Bardeen and Brattain in 1947, their development is one of the 20th century’s key scientific milestones. Transistors work by controlling electric current using an electric field, which requires semiconductors. Unlike metals, semiconductors have fewer free electrons and an energy band gap that makes it harder to excite electrons.
