The experimental demonstration of topological dissipation in photonic resonators
So far, physicists have primarily studied topological phases in conservatively coupled systems. These are systems with dynamics that do not dissipate and a phase space that does not shrink over time. They are in stark contrast with dissipative system.....»»
Luttinger"s theorem at the core of topological matter
In 1960, Joaquin Luttinger introduced a universal statement that relates the total number of particles that a system can accommodate to its behavior under low-energy excitations. While Luttinger's theorem is readily verified in systems of independent.....»»
Photonic chip that "fits together like Lego" opens door to semiconductor industry
Researchers at the University of Sydney Nano Institute have invented a compact silicon semiconductor chip that integrates electronics with photonic, or light, components. The new technology significantly expands radio-frequency (RF) bandwidth and the.....»»
Harvesting more solar energy with two-dimensional supercrystals

New constraints on the presence of ultralight dark matter in the Milky Way
Dark matter, composed of particles that do not reflect, emit or absorb light, is predicted to make up most of the matter in the universe. Its lack of interactions with light, however, prevents its direct detection using conventional experimental meth.....»»
Understanding the link between biodiversity loss and technology life cycles
The efforts to increase society's environmental sustainability focus on four major challenges that need to be addressed: climate change, natural resource dissipation, environmental pollution, and biodiversity loss......»»
Testing the limits of AlphaFold2"s accuracy in predicting protein structure
Proteins, the workhorses of biology, are encoded by DNA sequences and are responsible for vital functions within cells. Since the first experimental measurement of a protein structure was made by John Kendrew in the 1950s, protein's ability to fold i.....»»
First experimental evidence of hopfions in crystals: Research opens up new dimension for future technology
