Researchers have found evidence of a cataclysmic flare that punched outward in both directions from our galaxy’s center, reaching so far into intergalactic space that its impact was felt 200,000 light-years away.

2-D topological physics from shaking a 1-D wire
Limiting quantum particles to move in one, two, or three dimensions has led to the observation of many striking phenomena. A prime example is the quantization of the Hall conductance measured in 2-D materials in a strong magnetic field. Nowadays, gases of ultracold atoms provide a powerful platform for easily controlling the dimensionality of quantum systems. However, it is challenging in…
Study shows the non-exponential decay of a giant artificial atom
To date, research in quantum optics has primarily investigated the relation between light and matter using small atoms interacting with electromagnetic fields that have substantially larger wavelengths. In an unconventional new study, a team at Chalmers University of Technology in Sweden and the Max Planck Institute for the Science of Light set out to explore the interaction between a large atom…
Quantum teleportation used to send 3D information for the first time
Quantum teleportation has only ever been performed with qubits, which have two dimensions. Now it’s been done with a 3D qutrit for the first time Source: https://www.newscientist.com/article/2214135-quantum-teleportation-used-to-send-3d-information-for-the-first-time/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Scientists unveil first quantum simulation of 3-D topological matter with ultracold atoms
Physicists from the Hong Kong University of Science and Technology (HKUST) and Peking University (PKU) have successfully created the world’s first 3-D simulation of topological matter consisting of ultracold atoms. Previous attempts at topological matter simulations were limited to lower dimensions, due to challenges on how to characterize 3-D band topology in atomic systems. This breakthrough paves an opening to further…
Researchers propose new topological phase of atomic matter hosting ‘photonic skyrmions’
The field of topology or the study of how surfaces behave in different dimensions has profoundly influenced the current understanding of matter. The prime example is the topological insulator, which conducts electricity only on the surface while being completely insulating inside the bulk. Topological insulators behave like a metal, i.e., silver on the surface, but inside, it would behave like glass….
Atomic ‘Trojan horse’ could inspire new generation of X-ray lasers and particle colliders
How do researchers explore nature on its most fundamental level? They build “supermicroscopes” that can resolve atomic and subatomic details. This won’t work with visible light, but they can probe the tiniest dimensions of matter with beams of electrons, either by using them directly in particle colliders or by converting their energy into bright X-rays in X-ray lasers. At the heart…
Himalayan glaciers melting double fast since 2000
A new study, which used declassified images from spy satellites, shows that glaciers in the Himalayas melted twice as fast from 2000 to 2016 as they did from 1975 to 2000. Source: https://earthsky.org/earth/himalayan-glaciers-melting-double-fast-since-2000…
