Theoretical physicists have long been trying to devise a complete theory of gravity that would also account for quantum mechanics phenomena, as existing models do not. Such a theory could collectively explain the many intricate physical and cosmological phenomena...

A new approach to controlling the properties of turbulence
Turbulence, a fluid motion characterized by chaotic changes in flow velocity and pressure, has been the topic of countless physics studies. Although turbulence is a very common phenomenon that occurs in nature, manipulating it and controlling its properties had so far...
Study reveals the existence of the swallowtail catastrophe in non-Hermitian systems
Researchers from the Hong Kong University of Science and Technology, Xiangtan University and Southern University of Science and Technology recently unveiled a possible connection between catastrophe theory, an area of mathematics that focuses on modeling sudden...
The first experimental observation of subpicosecond electron bunches originating from an ultracold source
Identifying new sources that produce electrons faster could help to advance the many imaging techniques that rely on electrons. In a recent paper published in Physical Review Letters, a team of researchers at Eindhoven University of Technology demonstrated the...
The realization of a continuous time crystal based on a photonic metamaterial
A time crystal, as originally proposed in 2012, is a new state of matter in which the particles are in continuous oscillatory motion. Time crystals break time-translation symmetry. Discrete time crystals do so by oscillating under the influence of a periodic external...
The DarkSide experiment extends its search to dark matter–nucleon interactions
The DarkSide experiment is an ambitious research effort aimed at detecting dark matter particle interactions in liquid argon using a dual-phase physics detector located at the underground Gran Sasso National Laboratory. These interactions could be observed by...
New experimental evidence of the restoration of chiral symmetry at high matter density
The QCD vacuum (i.e., the ground state of vacuum in the quantum chromodynamics regime) is theoretically characterized by the presence of non-zero expectation values of condensates, such as gluons and quark–antiquark pairs. Instead of being associated with a lack of...
The ATLAS collaboration observes the electroweak production of two jets and a Z-boson pair
The ATLAS collaboration, the large research consortium involved in analyzing data collected by the ATLAS particle collider at CERN, recently observed the electroweak production of two Z bosons and two jets. This crucial observation, presented in Nature Physics,...
The SNO+ collaboration gathers the first evidence of antineutrinos in a water Cherenkov detector
Antineutrinos, the antimatter counterpart of neutrinos, have an almost non-existent mass and charge, and almost never interact with other particles, which makes them particularly difficult to detect. Physicists have been studying neutrinos from reactors for many...
A universal protocol that inverts the evolution of a qubit with a high probability of success
Researchers at the Institute for Quantum Optics and Quantum Information (IQOQI) in Vienna recently devised a universal mechanism to invert the evolution of a qubit with a high probability of success. This protocol, outlined in Physical Review Letters, can...
