Semiconductor moiré superlattices are fascinating material structures that have been found to be promising for studying correlated electron states and quantum physics phenomena. These structures, made up of artificial atom arrays arranged in a so-called moiré...
The absorption of water waves is the process through which water waves lose their energy, thus reducing their impact on shores or other solid structures surrounding them. Enabling this absorption process in real-world settings could help protect coasts and structures...
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...
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...
Superconductivity is the ability of some materials to conduct a direct electrical current (DC) with almost no resistance. This property is highly sought after and favorable for various technological applications, as it could boost the performance of different...
Light can excite electron and hole pairs inside semiconducting materials. If the attraction between a negatively charged electron and a positively charged hole (the antiparticle of electron in solid state physics) is strong, they stay bound together, forming states...
Mott insulators are a peculiar class of materials with structures that should theoretically conduct electricity, but that are instead insulators. These materials contain strongly correlated electrons, which can generate highly entangled many-body states marked by...
Magnetic skyrmions, statically stable magnetic quasiparticles with a topological charge, have been the focus of numerous recent studies, as they could support the development of so-called spintronics. These devices, which leverage the spin of electrons, could perform...
In recent years, physicists have been trying to attain the control of chemical reactions in the quantum degenerate regime, where de Broglie wavelength of particles becomes comparable to the spacing between them. Theoretical predictions suggest that many-body reactions...
