SU(N) Matter Is About Three Billion Times Colder Than Deep Space

An artist’s conception of the complex magnetic correlations physicists have observed with a groundbreaking quantum simulator at Kyoto University that uses ytterbium atoms about 3 billion times colder than deep space. Different colors represent the six possible spin states of each atom. The simulator uses up to 300,000 atoms, allowing physicists to directly observe...

Building a “Quantum Heat Pump” To Search For Elusive Dark Matter

Scientists have developed a heat pump that uses light particles on a quantum range. Scientists can currently measure radio frequency signals closer to the quantum limit. Professionals say this technique works in searching for dark matter, a component of the universe whose existence is discernible primarily by its gravitational attraction. 30.1 percent of the...

Japan’s Fugaku Supercomputer Powers Up Drug Discovery, Storm Forecasts

TOKYO-- Discovering brand-new drugs and also predicting severe weather is one of the tasks the Japanese-built Fugaku, 1 of the world's rapid supercomputer, has taken on as its applications broaden.Fugaku will certainly be at the center of a two-year experimental study research focused on a pharmaceutical development platform. The government-sponsored project, posted in July,...

Scientist Says That Dark Matter May Be Information Itself

Info DumpThere is no shortage of debate regarding the nature of the dark matter, a mysterious substance that many physicists believe makes up a large proportion of the total mass of the universe, despite never having observed it directly.Currently, a physicist from the UK called Melvin Vopson is raising a startling possibility: that dark...

A Particle New To Physics Could Solve the Dark Matter Mystery

Anomalies in nuclear physics experiments may show signs of a new force.A team of scientists in Hungary currently published a paper that hints at the presence of a previously unknown subatomic particle. The group first reported finding traces of the particle in 2016, and they now report more traces in a different experiment.If the...

Physicists Confirm the Existence Of Two-Dimensional Particles Called ‘Anyons’

After decades of exploration in nature's most minor domains, physicists have finally found proof that anyons exist. 1st predicted by theorists in the early 1980s, these particle-like objects arise in realms confined to two dimensions and then under certain circumstances-- like at temperatures near absolute zero and in the existence of a solid magnetic...

Scientists Develop Small Lens for Trapping Atoms

Graphical illustration of light focusing using a planar glass surface studded with millions of nanopillars (referred to as a metalens) forming an optical tweezer. (A) Device cross section depicts plane waves of light that come to a focus through secondary wavelets generated by nanopillars of varying size. (B) The same metalens is used to...

How Imaginary Numbers Describe the Fundamental Shape of Nature

Several science students may imagine a ball rolling down a hill or a car skidding due to friction as prototypical examples of the systems physicists care about. However, much of modern physics consists of looking for objects and essentially invisible sensations: the small electrons of quantum physics and the particles concealed within odd steels...

A Strange Brand-New Phase Of Matter Developed In Quantum Computers Acts Like It Has Two-Time Dimensions

The Penrose tiling pattern is a type of quasicrystal, which means that it has an ordered yet never-repeating structure. The pattern, composed of two shapes, is a 2D projection of a 5D square lattice. Credit: NoneBy shining a laser pulse series inspired by the Fibonacci numbers at atoms inside a quantum computer, physicists have...

A Quantum Double-slit Experiment Run with Molecules for the First time

Richard Feynman once stated that the double-slit experiment reveals the central challenges of quantum mechanics, putting us ''up against the and peculiarities of nature and paradoxes and mysteries''.Nandini Mukherjee, Richard Zare, and their co-workers at Stanford University, United States, have currently revealed that when helium (He) atoms collide with deuterium molecules (D2) in a quantum...
