Diamond quantum sensor could reveal elusive altermagnets

For nearly a century, there were two known kinds of magnets. Ferromagnets are the classic magnets that attract metal and keep pictures stuck to the refrigerator. Antiferromagnets hide their magnetism at the atomic scale but are increasingly prized for their technological potential. A third category discovered within the last decade may combine the best qualities of both. Dubbed altermagnets, they could someday help create faster, more energy-efficient electronics.

Antihydrogen mirrors hydrogen in upgraded spectrum test, narrowing cosmic mystery

University of Calgary researchers are a part of a group who just got one step closer to solving a mystery of the universe. Dr. Timothy Friesen, Ph.D., an associate professor of Physics and Astronomy in the Faculty of Science, and his team led a new measurement comparing the spectrum of hydrogen to its antimatter counterpart—antihydrogen.

Mars’s manganese ‘bathtub ring’ reveals ancient ocean timeline and its potential for life

Past research has indicated Mars’s largest northern basin, Utopia Planitia, was once the location of a large body of water, but details surrounding when this body of water may have existed have not been resolved. Researchers have now identified a ring of minerals in the region that have helped them string together a timeline of what happened there. The new study, published in Nature Communications, provides details about the ocean’s timeline and what it says about life on Mars.

Webb reveals black hole that formed before its galaxy

Which comes first, the galaxy or the black hole? We don’t know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can gobble up surrounding material and merge over time to form more massive entities.

A hidden supermassive black hole may be lurking inside the Antennae galaxies

Astronomers may have uncovered a hidden supermassive black hole inside the famous Antennae galaxies NGC 4038/4039, a pair of colliding galaxies best known for their spectacular bursts of star formation. The paper outlining the findings was posted to the arXiv preprint server on May 21.

Topological states emerge in quantum Hall-superconductor devices with multiple channels

Topological phases are unusual states of matter that give rise to properties protected by a material’s overall structure (i.e., “topology”), as opposed to microscopic details. These phases are of great interest for the development of quantum technologies, as they can yield desirable electronic properties that are robust against defects and disturbances.

‘Atom Camera’ maps laser light at nanoscale using a single ultracold atom

A research group led by Assistant Professor Takafumi Tomita and Professor Kenji Ohmori at the Institute for Molecular Science, National Institutes of Natural Sciences, has developed a new microscopy technique called the Atom Camera, which uses a single ultracold atom at near absolute zero temperature trapped in an optical tweezer as a camera to visualize the intensity and polarization distributions of light at the nanometer (one-millionth of a millimeter) scale.
