Were you aware that earthquakes are sometimes associated with luminescence, called earthquake lightning? This phenomenon had been documented throughout history, such as between 1965 and 1967, the Matsushiro earthquake swarm caused the surrounding mountain to flicker with light multiple times. In 1993 when an earthquake caused a tsunami off the coast in Southwest Hokkaido which caused 5 boats resting at shore to instantly ignite and burn. Various models have been proposed to explain earthquake […]

Helium atom precision measurements and calculations have a history of nearly a century. In the 1960s, theorists discovered that the fine-structure split (23P0-23P2) of the 23P energy level of helium is the best atomic system for measuring the fine structure constant α (approximately 1/137), which is the key parameter in the Quantum Electrodynamics (QED) theory. QED is the basic theory describing the quantum properties of electromagnetic interactions. It covers almost all physical systems from […]

Scientists investigate free electrons and the resonant interactions of electromagnetic waves in the field of plasmonics. However, the discipline still remains to be extended to large-scale commercial applications due to the loss-associated with plasmonic materials. While organic light-emitting devices (OLEDs) are incorporated into mass-scale commercial products due to properties such as good color saturation, versatile form factor and low-power consumption, their efficacy and stability remain […]

Through a one-of-a-kind experiment at the Department of Energy's Oak Ridge National Laboratory, nuclear physicists have precisely measured the weak interaction between protons and neutrons. The result quantifies the weak force theory as predicted by the Standard Model of Particle Physics.

A research team from Garching and Vienna discovered a remarkable echo effect that offers exciting new possibilities for working with quantum information.
