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 ...
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 ...
Figure 1: The shattering of glass is an archetypal fragmentation process. × When a solid object shatters or a liquid drop disintegrates, predicting the outcome seems at first hopelessly difficult. In ...
Experiments reveal the surprisingly large amount of entropy—and thus heat—generated by a clock that could be part of a quantum processor. Entropy generator. Any timekeeping device, such as an ...
A Bose-Einstein condensate of radioactive atoms could turn into a source of intense, coherent, and directional neutrino beams, according to a theoretical proposal. Figure 1: Top: At high temperature, ...
The efficiency of a quantum cryptography scheme can be improved by replacing conventional attenuated lasers with single-photon quantum-dot sources. Aerial view of the quantum key distribution ...
The many-worlds interpretation of quantum mechanics says that a measurement can cause a splitting of reality into separate worlds. The quantum-mechanics interpretation that suggests that new universes ...
Top quarks and antiquarks have been detected in heavy-ion collisions at the Large Hadron Collider, showing that all six quark flavors were present in the Universe’s first moments. The ATLAS ...
Time crystals realized in the so-called quasiperiodic regime hold promise for future applications in quantum computing and sensing. In ordinary crystals, atoms or molecules form a repeating pattern in ...
