The Mpemba effect is an intriguing physical phenomenon that causes some systems to cool faster when they are hot than when they are warm or colder. This effect was observed in various systems, including water, which sometimes freezes faster when it is hot than when it...
Amplified spontaneous emission is a physical phenomenon that entails the amplification of the light spontaneously emitted by excited particles, due to photons of the same frequency triggering further emissions. This phenomenon is central to the functioning of various...
Superconductivity, which entails an electrical resistance of zero at very low temperatures, is a highly desirable and thus widely studied quantum phenomenon. Typically, this state is known to arise following the formation of bound electron pairs known as Cooper pairs,...
Materials are known to interact with electromagnetic fields in different ways, which reflect their structures and underlying properties. The Lyddane-Sachs-Teller relation is a physics construct that describes the relationship between a material's static and dynamic...
Superconductivity is an intriguing property observed in some materials, which entails the ability to conduct electric current combined with an electrical resistance of zero at low temperatures. Physicists have observed this property in various solid materials with...
Phase transitions, shifts between different states of matter, are widely explored physical phenomena. So far, these transitions have primarily been studied in three-dimensional (3D) and two-dimensional (2D) systems, yet theories suggest that they could also occur in...
The so-called glass transition is the process by which some liquid-like materials become solid-like, without forming a crystalline structure. In contrast to conventional solid materials, which exhibit an orderly atom arrangement, glass is characterized by a disordered...
Spin Hall nano-oscillators (SHNOs) are nanoscale spintronic devices that convert direct current into high-frequency microwave signals through spin wave auto-oscillations. This is a type of nonlinear magnetization oscillations that are self-sustained without the need...
Quantum computers have the potential of outperforming classical computers on some optimization and computational tasks. Compared to classical systems, however, quantum systems are more prone to errors, as they are more sensitive to noise and prone to so-called...
Superionic materials are a class of materials that simultaneously present properties that are characteristic of solids and liquids. Essentially, a set of ions in these materials exhibits liquid-like mobility, even if the materials' underlying atomic structure...
