Very soon after the Big Bang, the universe enjoyed a brief phase where quarks and gluons roamed freely, not yet joined up into hadrons such as protons, neutrons and mesons. This state, called a quark-gluon plasma, existed for a brief time until the temperature dropped to about 20 trillion Kelvin, after which this "hadronization" took place. /news/2025-05-thermodynamic-properties-quark-gluon-plasma.html General Â鶹ÒùÔºics Plasma Â鶹ÒùÔºics Fri, 30 May 2025 10:00:03 EDT news667816855 What if the magnon Hall effect, which processes information using magnons (spin waves) capable of current-free information transfer with magnets, could overcome its current limitation of being possible only on a 2D plane?

In condensed matter physics, a Majorana zero mode (MZM) is a quasi-particle excitation that appears in the surfaces or edges of topological superconductors. Unlike the ordinary particles or quasi-particles that obey boson or fermion statistics, MZM obeys non-abelian statistics, a key property that makes MZM the building block for realizing topological quantum computation. /news/2021-07-higher-order-topological-superconductivity-monolayer-iron-based.html Superconductivity Quantum Â鶹ÒùÔºics Wed, 14 Jul 2021 08:19:46 EDT news545469583 Quantum spin Hall insulators are a class of two-dimensional (2D) topological states of matter that are electrically insulating in their interior but, unlike semiconductors, carry a pair of one-dimensional (1D) metallic states, which are strictly confined to their edges. /news/2021-05-electrons-edge-atomically-thin-quantum.html Nanophysics Nanomaterials Fri, 28 May 2021 08:17:07 EDT news541408623 Oscillatory behaviors are ubiquitous in nature, ranging from the orbits of planets to the periodic motion of a swing. In pure crystalline systems, presenting a perfect spatially-periodic structure, the fundamental laws of quantum physics predict a remarkable and counter-intuitive oscillatory behavior: when subjected to a weak electric force, the electrons in the material do not undergo a net drift, but rather oscillate in space, a phenomenon known as Bloch oscillations. Ultracold atoms immersed in a light crystal, also known as optical lattices, are one of the many systems where Bloch oscillations have been observed. /news/2020-11-quantum.html Quantum Â鶹ÒùÔºics Mon, 23 Nov 2020 13:26:39 EST news525360397
