Coupled semiconductor lasers generate novel optical patterns, enabling new spectroscopy techniques
The physical interaction between two or more systems, also known as coupling, can give rise to unique and unexpected effects. In the field of optics, coupled light sources (e.g., lasers) can influence each other, producing complex light patterns that cannot be emitted...
NEON experiment shares results from first direct search for light dark matter
Detecting dark matter, the elusive type of matter predicted to account for most of the universe's mass, has so far proved to be very challenging. While physicists have not yet been able to determine what exactly this matter consists of, various large-scale experiments...
Using phononic bandgap materials to suppress decoherence in quantum computers
Quantum computers have the potential of outperforming classical computers on some optimization and computational tasks. Compared to classical systems, however, quantum systems are more prone to errors, as they are more sensitive to noise and prone to so-called...
