The field of quantum communication has taken a significant leap forward with groundbreaking research published in Nature Communications by an international team from Wits and ICFO – The Institute of Photonic Sciences. The research showcases the teleportation-like transport of “patterns” of light, marking a crucial milestone towards achieving a quantum network for high-dimensional entangled states.
Each year, the American Physical Society’s Division of Fluid Dynamics holds an annual meeting where they showcase the mesmerizing beauty of flowing fluids. This event includes a contest that recognizes outstanding images and videos related to the dynamics of liquids and gases. The 76th meeting, held in Washington, D.C. in November, unveiled a collection of
When the Large Hadron Collider (LHC) smashes together two lead ions, it creates a unique state of matter known as quark-gluon plasma (QGP). This QGP, which is believed to have existed in the early universe moments after the Big Bang, provides valuable insights into the fundamental properties of matter. In a recent study, the ALICE
The absorption of water waves has long been a topic of interest for researchers aiming to devise effective strategies to protect coasts and structures from wave-induced damage. Recently, a team of researchers from various institutions, including Sorbonne Université CNRS and University of Bristol, introduced a promising new strategy for achieving efficient water wave absorption. In
The field of materials science continues to push the boundaries of scientific discovery, with the aim of developing innovative technologies that drive progress.

On the highway of heat transfer, thermal energy is traditionally moved through quantum particles known as phonons. However, in today’s nanoscale semiconductors, the efficacy of phonons in removing heat has reached its limit. This limitation has led researchers at Purdue University to focus on harnessing the potential of a novel type of quasiparticles called “polaritons”
In 1960, Joaquin Luttinger presented a groundbreaking statement that established a relationship between the behavior of a system’s low-energy excitations and the total number of particles it can accommodate. This theorem held true not only in systems of independent particles but also in correlated quantum matter with strong interactions between the particles. However, recent research
