Recent advances in the observation of high-energy radiations, including X-rays and gamma-rays, have unveiled many high-energy aspects of the universe. To achieve a complete understanding of these radiations, however, researchers need to find out more about the...

A ten-qubit solid-state spin register with remarkable quantum memory
In years to come, quantum computers and quantum networks might be able to tackle tasks that are inaccessible to traditional computer systems. For instance, they could be used to simulate complex matter or enable fundamentally secure communications.
A theoretical explanation for an enhanced thermal Hall response in high-temperature superconductors
A few months ago, a team of researchers led by Louis Taillefer at the University of Sherbrooke measured the thermal Hall conductivity in several compounds of copper, oxygen and other elements that are also high-temperature superconductors known as 'cuprates.' In...
Coupling qubits to sound in a multimode cavity
In a recent study, researchers at the University of Colorado have resolved phonon Fock states in the spectrum of a superconducting qubit coupled to a multimode acoustic cavity. Fock states (or number states) are quantum states with a clearly defined number of...
A new theoretical model to capture spin dynamics in Rydberg molecules
Rydberg molecules are giant molecules made up of tens or hundreds of atoms bound to a Rydberg atom. These molecules have a permanent dipole (i.e., a pair of oppositely charged or magnetized poles), as one of their atoms is in a highly excited state.
A quantum simulation of Unruh radiation
Researchers at the University of Chicago (UChicago) have recently reported an experimental observation of a matter field with thermal fluctuations that is in accordance with Unruh's radiation predictions. Their paper, published in Nature Physics, could open up new...
An electronically tunable metasurface that rotates polarization
Researchers at the University of Michigan and City University of New York have recently proposed and experimentally validated a transparent, electronically tunable metasurface. This metasurface, presented in a paper published in Physical Review X, can rotate the...
A new framework to predict spatiotemporal signal propagation in complex networks
Past studies have found that a variety of complex networks, from biological systems to social media networks, can exhibit universal topological characteristics. These universal characteristics, however, do not always translate into similar system dynamics. The dynamic...
A new metric to capture the similarity between collider events
Researchers at the Massachusetts Institute of Technology (MIT) have recently developed a metric that can be used to capture the space of collider events based on the earth mover's distance (EMD), a measure used to evaluate dissimilarity between two multi-dimensional...
Alpha Magnetic Spectrometer measurements unveil properties of cosmic helium
The Alpha Magnetic Spectrometer (AMS) collaboration, a large group of researchers from CERN and other institutes worldwide, has recently presented a series of precision measurements of the properties of cosmic Helium isotopes 3He and 4He. These measurements were...
