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 ...
At TU Wien, researchers have discovered a state in a quantum material that had previously been considered impossible. The definition of topological states should be generalized.
In the past year, two separate experiments in two different materials captured the same confounding scenario: the coexistence of superconductivity and magnetism. Scientists had assumed that these two quantum states are mutually ...
Researchers from Japan have discovered a unique Hall effect resulting from deflection of electrons due to "in-plane magnetization" of ferromagnetic oxide films (SrRuO3). Arising from the spontaneous coupling of spin-orbit ...
Magic-angle twisted bilayer graphene (MATBG) is a material created by stacking two sheets of graphene onto each other, with a small twist angle of about 1.1°. At this "magic angle," electrons move very slowly, which can lead ...
In a new publication in Nature Materials, an international team of researchers has developed groundbreaking artificial chains of the iconic "olympicene" molecules to realize the antiferromagnetic (AF) spin-½ Heisenberg model, ...
Graphene, a single layer of carbon atoms arranged in a two-dimensional honeycomb lattice, is known for its exceptional properties: incredible strength (about 200 times stronger than steel), light weight, flexibility, and ...
Moiré superlattices are materials consisting of two layers stacked on top of each other with either a small rotational misalignment or a lattice mismatch between them. The Kondo lattice model, on the other hand, describes ...
Unconventional superconducting states are states of superconductivity rooted in physical processes that do not conform with the conventional theory of superconductivity, namely Bardeen, Cooper and Schrieffer (BCS) theory. ...
A new magnetic material developed by RIKEN physicists could boost computer memory storage by enabling higher memory density and faster memory writing speeds. Their research has been published in the journal Nature Communications.
