Researchers observe atoms trapped in an optical lattice mimicking particles created in a strong electric field. In physics, you can get something from nothing. In a strong electric field, electrons ...
A decades-old neutrino mystery might be solved not by undiscovered physics but by improved calculations.
A hallmark property of unconventional superconductivity has been discovered in a type-I superconductor, whereas it’s normally observed only in type-II materials. Superconductors can be broadly ...
New experiments suggest that superconductivity in twisted bilayer graphene depends on an unconventional electron-pairing mechanism. Figure 1: Two twisted bilayer graphene (TBG) layers stacked one on ...
A ring of optical fiber can be made to host phenomena that originated in the realm of high-energy physics. Yang and his colleagues achieved their feat using a platform based on fiber ring resonators, ...
Experiments show signs of a material that conducts electricity in opposite directions along its edges through fractionally charged quasiparticles. Zhu and his colleagues added electron vacancies, or ...
Different analyses of gravitational-wave observations are converging on evidence for a distinct population of massive black hole binaries produced through repeated mergers. Figure 1: Hundreds of ...
Figure 1: Barrios Hita and colleagues have explored a new path for developing a formulation of quantum theory that doesn’t rely on complex numbers [5]. In standard quantum theory, every physical ...
Figure 1: A cross section of the core of a collapsing star. Electron neutrinos (blue arrows) and muon and tau neutrinos (green arrows) are emitted and absorbed within all parts of the core. In the ...
Before determining the correct quantum theory of gravity, researchers need to know if gravity is actually quantized. Experiments testing that assumption are now being developed. Quantum fluctuations ...
Measurements of the decay of the Higgs boson into muon–antimuon pairs provide evidence for the mechanism by which quarks and leptons acquire their mass. Figure 1: Display of a proton–proton collision ...
In 1927, Niels Bohr introduced complementarity to quantum mechanics. A pair of complementary properties cannot be observed or measured simultaneously, he asserted. Finding the concept unpalatable, ...
