Whispering gallery modes, a type of wave that can travel around concave surfaces, have proved to be promising for the development of new technologies, particularly in photonics. Due to geometrical limitations, in circularly symmetric optical microresonators (i.e.,...

The observation of an anomalous Hall effect in altermagnetic ruthenium dioxide
The Hall effect is a conduction phenomenon discovered by physicist Edwin Herbert Hall that describes the development of a transverse electric field in solid materials carrying electric current that are placed in a magnetic field perpendicular to this current. In the...
A scalable quantum memory with a lifetime over 2 seconds and integrated error detection
Quantum memory devices can store data as quantum states instead of binary states, as classical computer memories do. While some existing quantum memory technologies have achieved highly promising results, several challenges will need to be overcome before they can be...
Using machine learning to infer rules for designing complex mechanical metamaterials
Mechanical metamaterials are sophisticated artificial structures with mechanical properties that are driven by their structure, rather than their composition. While these structures have proved to be very promising for the development of new technologies designing...
Evidence of Higgs boson contributions to the production of Z boson pairs at high energies
The Higgs boson, the fundamental subatomic particle associated with the Higgs field, was first discovered in 2012 as part of the ATLAS and CMS experiments, both of which analyze data collected at CERN's Large Hadron Collider (LHC), the most powerful particle...
A single fiber actuator inspired by human muscles
To effectively replicate the movements of humans and animals, robots should integrate muscle-like structures. These artificial muscles should attain an optimal performance across all relevant actuation parameters, including energy density, strain, stress, and...
Physics study shows that sheep flocks alternate their leader and achieve collective intelligence
The collective motion of animals in a group is a fascinating topic of research for many scientists. Understanding these collective behaviors can sometimes inspire the development of strategies for promoting positive social change, as well as technologies that emulate...
Recent searches for light fermionic dark matter by the PandaX-4T collaboration
Teams of astrophysicists worldwide are trying to observe different possible types of dark matter (DM), hypothetical matter in the universe that does not emit, absorb or reflect light and would thus be very difficult to detect. Fermionic DM, however, which would be...
Study demonstrates tailored Ising superconductivity in intercalated bulk niobium diselenide
When 2D layered materials are made thinner (i.e., at the atomic scale), their properties can dramatically change, sometimes resulting in the emergence of entirely new features and in the loss of others. While new or emerging properties can be very advantageous for the...
Study unveils the compositions and origins of global airborne bacteria on Earth
Microbiomes, microorganisms that populate specific environments, are known to include both beneficial and harmful bacterial species. Understanding how destructive microbiomes originate in changing environments and their effects on both the environment and human health...
