Perimeter Institute for Theoretical Physics Examines the Multiverse Hypothesis

In several new studies and a short video, researchers from the Perimeter Institute for Theoretical Physics detail their work on the multiverse hypothesis. Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science. Never […]

ATLAS Collaboration Detects Process Even Rarer than the Higgs Particle

A new published study from the ATLAS Collaboration reports the first evidence of a process that can be used to test the mechanism by which the recently discovered Higgs particle imparts mass to other fundamental particles. Scientists running the ATLAS experiment at the Large Hadron Collider (LHC), the world’s largest and most powerful “atom smasher,” […]

Researchers Consider the Anticrystal

Physicists show that the anticrystal, a theoretical solid that is completely disordered, should undergird our understanding of most materials. For the last century, the concept of crystals has been a mainstay of solid-state physics. Crystals are paragons of order; crystalline materials are defined by the repeating patterns their constituent atoms and molecules make. Now physicists […]

New CERN Data Bolsters Higgs Boson Discovery

New research published in Nature Physics details strong evidence of the direct decay of the Higgs boson to fermions. If evidence of the Higgs boson revealed two years ago was the smoking gun, particle physicists at Rice University and their colleagues have now found a few of the bullets. The European Organization for Nuclear Research […]

Breakthrough in Identifying the Origin of Superconductivity

Researchers from the University of Cambridge have made a breakthrough in identifying the origin of superconductivity in high-temperature superconductors. They discovered that ripples of electrons, known as charge density waves or charge order, create twisted ‘pockets’ of electrons in these materials, from which superconductivity emerges. Harnessing the enormous technological potential of high-temperature superconductors – which […]

Quantum Computations on a Topologically Encoded Qubit

Physicists have experimentally encoded one qubit in entangled states distributed over 7 trapped-ion qubits and demonstrate the capability of the code to detect one bit flip, phase flip or a combined error of both, regardless on which of the qubits they occur. In a close collaborative effort, Spanish and Austrian physicists have experimentally encoded one […]

Invisibility Cloaks for Visible Light in Diffusive Media

Physicists from the Karlsruhe Institute of Technology have developed a simple method for building and testing an invisibility cloak for diffusive light-scattering media. Real invisibility cloaks are rather complex and work in certain situations only. The laws of physics prevent an optical invisibility cloak from making objects in air invisible for any directions, colors, and […]

New Research Reveals the Turbulent Behavior of Black Holes

A new study from the Perimeter Institute for Theoretical Physics reveals the turbulent nature of black holes, showing that gravitational fields around black holes might eddy and swirl. Fasten your seatbelts – gravity is about to get bumpy. Of course, if you’re flying in the vicinity of a black hole, a bit of extra bumpiness […]

A New Discovery of Quantum Critical Points

Physicists have discovered new “quantum critical points” in a class of iron superconductors known as “oxypnictides,” furthering their understanding of quantum criticality. Quantum criticality, the strange electronic state that may be intimately related to high-temperature superconductivity, is notoriously difficult to study. But a new discovery of “quantum critical points” could allow physicists to develop a […]

A Path Toward More Powerful Tabletop Accelerators

Berkley Lab researchers show how beams of various colors and phases affect plasma, finding that laser light needn’t be as precise as previously thought to drive miniature particle accelerators. Making a tabletop particle accelerator just got easier. A new study shows that certain requirements for the lasers used in an emerging type of small-area particle […]

New Study Reveals Clues about How Ultracold Atoms Interact

Using a vacuum system that isolates ultracold atoms from room temperature and pressure, scientists reveal new clues about how ultracold atoms interact. Assembling the puzzles of quantum materials is, in some ways, like dipping a wire hanger into a vat of soapy water, says the University of Toronto’s Joseph Thywissen, faculty member in the physics […]
