The Big Bang is often described as the explosive birth of the universe—a singular moment when space, time and matter sprang into existence. But what if this was not the beginning at all? What if our universe emerged from something else—something more familiar and radical at the same time? /news/2025-06-big-wasnt-black-hole.html Astronomy Wed, 04 Jun 2025 12:56:33 EDT news668260585 Nature categorizes particles into two fundamental types: fermions and bosons. While matter-building particles such as quarks and electrons belong to the fermion family, bosons typically serve as force carriers—examples include photons, which mediate electromagnetic interactions, and gluons, which govern nuclear forces. /news/2025-05-dimensional-anyons-exotic-quasiparticles-coldest.html Quantum Â鶹ÒùÔºics Wed, 28 May 2025 11:00:07 EDT news667639621 When two-dimensional electron systems are subjected to magnetic fields at low temperatures, they can exhibit interesting states of matter, such as fractional quantum Hall liquids.

When comparing two-and three-site chains within the same device, they observed that extending the chain to three sites increased the stability of the zero-energy modes. This work demonstrates the scalability of quantum-dot-based Kitaev chains and their potential to host stable Majorana zero modes. The researchers published their results in Nature Nanotechnology. /news/2025-03-site-kitaev-chain-stability-majorana.html Nanophysics Mon, 31 Mar 2025 13:45:03 EDT news662647501 Quantum critical points are thresholds that mark the transition of materials between different electronic phases at absolute zero temperatures, around which they often exhibit exotic physical properties. /news/2025-03-mechanism-underpinning-intrinsic-strange-metal.html Condensed Matter Quantum Â鶹ÒùÔºics Sun, 30 Mar 2025 09:40:02 EDT news662373115 Does the proton decay?

However, in topology, which is a branch of mathematics, one must do just that. Apples and oranges, it turns out, are said to be topologically the same since they both lack a hole—in contrast to doughnuts or coffee cups, for instance, which both have one (the handle in the case of the cup), and thus are topologically equal. /news/2024-04-reveals-topological-reversal-quantum.html Quantum Â鶹ÒùÔºics Thu, 18 Apr 2024 15:22:03 EDT news632672521 An international research team from Innsbruck and Geneva has, for the first time, probed the dimensional crossover for ultracold quantum matter.
