Figure 1: Moore and his colleagues measured the momentum kick imparted by a single gas molecule on an optically levitated silica nanoparticle (center) [2]. Thanks to the isolation offered by setups ...

Increasing the charging rate of a quantum battery leads to unavoidable fluctuations in the total energy stored. A quantum battery exploits quantum correlations between its component cells to achieve ...

Two studies find that fundamental quantum constraints rule out a previously proposed neutrino-laser scheme. In last year’s proposal of a neutrino laser, the researchers sought to exploit the same ...

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: The beam pipe of the LHCb experiment at CERN. The beam pipe’s main function is to sustain an ultrahigh vacuum for the colliding proton beams while enabling particles produced in the ...

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 ...

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.

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, ...

A proposed experiment could shed light on the unknown interplay of quantum theory and general relativity. Quantum theory in curved spacetime can be theoretically understood beyond the limit at which ...

New physics may explain discrepant values for the ionization energy of a metastable state of helium. Aaron Bondy is a theoretical physicist at Drake University in Iowa, where he works as a ...

For a wide range of complex fluids, the transition from solid-like at rest to liquid-like when pushed can be predicted from properties of the at-rest state. Slow flow. Slow flow. Yield stress fluids ...

A high-resolution imaging system captures distant objects by shining laser light on them and detecting the reflected light. Seeing the small picture. The remote-imaging system (left) shoots eight ...
