Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical ...
Cornell researchers have developed a new way to create moiré patterns—atomic-scale structures that can give materials unusual quantum behaviors—without relying on the traditionally used difficult-to-control twisting and stacking ...
Superconductors are materials that can conduct electricity with a resistance of zero. In so-called conventional superconductors, this occurs at low temperatures when electrons become bound into pairs, known as Cooper pairs.
Superconductors, materials that can conduct electricity with a resistance of zero, have proved to be highly promising for the development of quantum technologies, medical imaging devices, particle accelerators and other advanced ...
The electrons that power our society flow left and right through the circuitry in our electronics, back and forth along the transmission lines that make up our power grid, and up and down to light up every floor of every ...
Superconductivity—the ability of a material to conduct electricity without any energy loss to heat—enables highly efficient, ultra-fast electronics essential for advanced technologies such as magnetic resonance imaging (MRI) ...
When mobile charge carriers, also known as itinerant electrons, interact with the strong exchange magnetic fields associated with the intrinsic angular momentum of localized electrons, this can give rise to the so-called ...
Conventional crystals are materials in which atoms arrange themselves in repeating spatial patterns. Time crystals, on the other hand, are phases of matter characterized by repeating motions over time without constantly heating ...
In some quantum materials, which are materials governed by quantum mechanical effects, interactions between charged particles (i.e., electrons) can prompt the creation of quasiparticles called anyons, which carry only a fraction ...
Two or more graphene layers that are stacked with a small twist angle in relation to each other form a so-called moiré lattice. This characteristic pattern influences the movement of electrons inside materials, which can ...
