Physicists are shedding new light on an ancient quantum optics problem with collective behaviour

Credit: Gerd Altman from Pixabay When atoms interact with each other, they act as a whole and not as individual entities. This can lead to simultaneous responses to inputs, a phenomenon that, if properly understood and controlled, could be useful for developing light sources, building sensors that can take ultra-precise measurements, and understanding dissipation in … Read more

New algorithm approach paves the way for larger, more complex metallic lenses

Metal fabricated with a small LCD screen displaying the Harvard logo. Credit: Capasso Lab / Harvard SEAS Compact and lightweight surfactants—which use specially designed and stylized nanostructures on a flat surface to focus, shape, and control light—are a promising technology for wearable applications, especially virtual and augmented reality systems. Today, research teams design a specific … Read more

Insights for better characterization of nuclear physics and the harsh environments of cosmic explosions

An illustration of a conventional modern nova shows a bright white dwarf star near the center accumulating fuel in an orange disk of its neighboring main-sequence star (highlighted in bright orange). Credit: NASA/JPL-Caltech Michigan State researchers helped peer inside a new supernova – a type of astrophysical nuclear explosion – without leaving Earth. These stellar … Read more

Building a better black hole with supercomputer simulation

Astronomers have used a potentially unlikely tool to understand what they saw in their first historic image of the Milky Way’s supermassive black hole: a library of computer simulations that simulate a black hole with millions of variations. photo shoot Black holeLike Sagittarius A* In the center of our galaxy, with event horizon telescope (EHT) … Read more
