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 ...

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 ...

Through a quantum-switch experiment, researchers attempt to reveal “indefinite causal order”—a quantum phenomenon involving events in a before-and-after superposition. Artistic rendition of 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 ...

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 ...

Two direct-detection experiments see no evidence of a signal reported by their predecessor. In 1997, the DAMA/NaI experiment observed a signal whose annual variability was suggestive of dark matter.

First contact. A scanning tunneling microscope’s (STM’s) atomically sharp tip, made of normal-metal atoms (blue spheres), approaches a phthalocyanine molecule (blue and white peaks, representing the ...

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 ...

Microsoft’s announcement of achieving a milestone in a potentially transformative approach to quantum computing is met with skepticism by researchers attending the APS Global Summit. Microsoft's ...

Tech giant Microsoft claimed in a recent press release to have made the first topological qubit–an important milestone in the development of quantum computers. But some experts say the firm’s claim ...

The creation of modern quantum mechanics was a messy business in which many of the participants did not grasp the significance of their own discoveries. The wave nature of electrons is revealed in ...
