Luttinger's theorem at the center of topology
Luttinger’s theorem at the center of topology
The laws of physics are based on universal principles, often associated with mathematical theorems. Identifying physical phenomena that escape these fundamental rules leads to a paradigm shift, and usually to major discoveries. In a paper published in Physical Review Letters, Lucila Peralta Gavensky, Nathan Goldman (Faculty of Science) and Subir Sachdev (Harvard), reveal a fundamental link between the violation of two major rules of solid-state physics: Luttinger's theorem and the classification rule for insulating materials .

FNRS researcher Tárcius Nascimento Ramos publishes in the prestigious Journal of Chemical Physics
Knowing the energy of light absorbed by a molecule enables us to understand its structure, its quantum states, its interaction with other molecules and its potential technological applications. Molecules with a high probability of simultaneously absorbing two low-energy photons of light have a wide range of applications: as molecular probes in high-resolution microscopy, as substrates for data storage in dense three-dimensional structures or as vectors in medicinal treatments.

Euclid: a European space telescope to reveal the invisible universe
Euclid: a European space telescope to reveal the invisible universe
Euclid is a telescope of the European Space Agency (ESA) which aims to reveal the properties and nature of dark matter and dark energy - 95% of the contents of the Universe. On the occasion of its launch from Cape Canaveral in early July, Belgian scientists involved in the Euclid mission, notably from the Université libre de Bruxelles, are highlighting their contributions and research projects .

New algorithm enables simulation of complex quantum systems
An international team of scientists from the University of Luxembourg, Berlin Institute for the Foundations of Learning and Data (BIFOLD) at TU Berlin and Google has now successfully developed a machine learning algorithm to tackle large and complex quantum systems. The article has been published in the renowned journal Science Advances.

A new approach for solving the dark energy mystery
What is behind dark energy - and what connects it to the cosmological constant introduced by Albert Einstein? Two physicists from the University of Luxembourg point the way to answering these open questions of physics. The universe has a number of bizarre properties that are difficult to understand with everyday experience.

Direct observation of ideal electromagnetic fluids
Direct observation of ideal electromagnetic fluids
What is a perfect fluid - It is a theoretical model of a fluid that allows to assume that the fluid is not viscous, that it does not conduct heat, that it is incompressible and does not create vortices. It is therefore an approximation of reality that simplifies the theoretical predictions of fluid flows.

Tiny but Mighty: Atomic Forces at the Engineering Scale
An interdisciplinary manuscript reporting on a collaboration between physicists and computational engineers from the University of Luxembourg and Padova (Italy) has been published in Physical Review Letters. This work reveals that interactions between many electrons in materials can induce a colossal enhancement of atomic forces at the nanoscale and in large engineering-scale systems.

Chasing neutrinos in Greenland
VUB leads pioneering project to search for cosmic particles from space with radio antennas Researchers from the Vrije Universiteit Brussel (VUB) are part of a unique installation on the Greenland ice cap that will try to observe almost elusive particles from space. The Radio Neutrino Observatory Greenland (RNO-G) is a pioneering project that uses a new method to detect cosmic neutrinos with very high energy using radio antennas.

Nature publication IceCube in Antarctica proves 60-year-old physics prediction with high-energy particle from the Universe
In 1960, Nobel Prize winner Sheldon Glashow predicted a process within the Standard Model, the most important model of particle physics. The theory describes the interaction of an antineutrino with an electron producing a new particle. However, no particle accelerator on Earth, not even the Large Hadron Collider at CERN, is able to make this process happen because it requires extremely high particle energy.

Flat bands appear in buckled graphene superlattices
Recent research published by the CMT group in collaboration with Rutgers University uncover a novel way of achieving flat bands in through strain superlattices. An international team led by researchers at Rutgers University in the US has found a way to create "flat? electronic bands - that is, electron states in which there is no relationship between the electrons' energy and velocity - in graphene simply by causing the material to buckle.

KU Leuven researchers shed new light on solar flares
KU Leuven researchers shed new light on solar flares
Plasma astrophysicists at KU Leuven have created the first self-consistent simulation of the physical processes that occur during a solar flare. The researchers used Flemish supercomputers and a new combination of physical models. Solar flares are explosions on the surface of the Sun that release an enormous amount of energy, equivalent to a trillion 'Little Boy' atomic bombs exploding at the same time.

Exotic particles offer deeper insight into matter and antimatter
At the European nuclear and particle physics laboratory CERN, physicists can produce extremely rare short-lived atoms and molecules. Researchers from KU Leuven have shown that these particles lead the way to uncharted territory in nuclear and particle physics. One of the oldest active installations at the Centre for European Nuclear Research (CERN) in Geneva is the ISOLDE laboratory.

Clusters of gold atoms form peculiar pyramidal shape
Freestanding clusters of twenty gold atoms take the shape of a pyramid, researchers discovered. This is in contrast with most elements, which organize themselves by forming shells around one central atom. The team of researchers led by KU Leuven published their findings in Science Advances . Clusters composed of a few atoms tend to be spherical.
