Nano rainbows : Expanding the light spectrum at the smallest scale

13 janvier

Since the invention of the laser in 1960, nonlinear optics has aimed to broaden light’s spectral range and create new frequency components. Among the various techniques, supercontinuum (SC) generation stands out for its ability to produce light across a wide portion of the visible and infrared (…)

Cosmic shock waves : Unraveling the mystery of electron acceleration

13 janvier

Scientists have come a step closer to understanding how collisionless shock waves—found throughout the universe—are able to accelerate particles to extreme speeds.

Physicists discover and explain unexpected magnetism in atomically thin material

13 janvier

MIT physicists have created a new ultrathin, two-dimensional material with unusual magnetic properties that initially surprised them before they went on to solve the complicated puzzle behind those properties’ emergence. As a result, the work introduces a new platform for studying how materials (…)

Scientists achieve measurement of three different deformations in atomic nucleus

13 janvier

A new milestone in nuclear physics has been achieved with the direct observation of three different deformations in the atomic nucleus of lead-190 (190Pb). These deformations, associated with three distinct shapes—spherical, oblate (resembling a tomato), and prolate (similar to a (…)

Quantum computer helps to answer questions on lattice gauge theory

13 janvier

Science is always looking for more computing power and more efficient tools capable of answering its questions. Quantum computers are the new frontier in data processing, as they use the quantum properties of matter, such as the superposition of states and entanglement, to perform very complex (…)

Physicists develop the ’perfect’ recipe for a well-known Italian pasta dish

13 janvier

A small team of physicists at the Max Planck Institute for the Physics of Complex Systems, working with a colleague from Universitat de Barcelona and another from the Institute of Science and Technology Austria, has developed what they describe as a foolproof recipe for cacio e pepe.

New approach merges theoretical fundamentals with experimental studies of the proton’s structure

13 janvier

Protons and other subatomic particles that are subject to the strong nuclear force have a complex structure that involves even more fundamental constituents called quarks and gluons. These quarks and gluons bind under the influence of quantum chromodynamics (QCD). QCD is the theory of strong (…)

Physicists experimentally observe topological defects in glasses for the first time

13 janvier

The amorphous state of matter is the most abundant form of visible matter in the universe, and includes all structurally disordered systems, such as biological cells or essential materials like glass and polymers.

Collaboration tests new method for protecting quantum networks

13 janvier

Researchers at the Department of Energy’s Oak Ridge National Laboratory joined forces with EPB of Chattanooga and the University of Tennessee at Chattanooga to demonstrate the first transmission of an entangled quantum signal using multiple wavelength channels and automatic polarization (…)

Quantum breakthrough may lead to sustainable chiral spintronics

11 janvier

A team of physicists led by The City College of New York’s Lia Krusin-Elbaum has developed a novel technique that uses hydrogen cations (H+) to manipulate relativistic electronic bandstructures in a magnetic Weyl semimetal—a topological material where electrons mimic massless particles called (…)
