When a negatively charged electron and a positively charged hole in a pair remain bound together following excitation by light, they produce states known as excitons. These states can influence the optical properties of materials, in turn enabling their use for...
In recent years, physicists have been trying to better understand how quantum information spreads in systems of interacting particles—a phenomenon often referred to as "scrambling." Scrambling in closed systems, physical systems that can only exchange energy with...
The Muon g-2 Collaboration is a large group of researchers at different institutes worldwide collaborating on the Muon g-2 experiment. This is a research effort aimed at exploring the interactions of muons, short-lived particles that are essentially heavy electrons,...
Cooper pairs are pairs of electrons in superconducting materials that are bound to each other at low temperatures. These electron pairs are at the root of superconductivity, a state where materials have zero resistance at low temperatures due to quantum effects. As...
To build highly performing quantum computers, researchers should be able to reliably derive information about the noise inside them, while also identifying effective strategies to suppress this noise. In recent years, significant progress has been made in this...
High-temperature cuprate superconductors are a broad class of materials that exhibit some unique characteristics. Due to their distinctive properties, these materials exhibit the highest superconducting temperatures reported to date under ambient pressure.
Phonons, quasi-particles associated with sounds or lattice vibrations, can carry momentum and angular momentum. However, these quasi-particles are commonly considered to possess negligible magnetic moments.
Bulk acoustic resonators—stacked material structures inside which acoustic waves resonate—can be used to amplify sounds or filter out undesired noise. These resonators have found wide use in today's RF telecommunication, like Front-End Modules (FEM) in iPhones. They...
A hypertriton is a tritium nucleus in which a neutron is replaced by a so-called Lambda hyperon. This type of hypernucleus was first discovered in the 1950s has since been the key focus of numerous studies.
Quantum entanglement is a physical process through which pairs of particles become connected and remain so even when separated by vast distances. This fascinating phenomenon has been the focus of numerous research studies, due to its mysterious nature and promising...
