What is a Quantum Spin Hall Insulator? A quantum spin Hall insulator (QSHI) is a novel state of matter that exhibits unique electronic properties. It is a type of topological insulator, which is a ...

It's based on a quantum phenomenon called Quantum Anomalous Hall effect. The precise measurement ... a physicist at the Institute for Topological Insulators at the University of Würzburg (JMU).

The existence of an energy gap, however, does not guarantee that a material is a simple insulator. A counterexample is the two-dimensional integer quantum Hall state, which has an energy gap due ...

Led by Boston College physicist Qiong Ma, an international team working with single-atom thick crystals found TaIrTe4's transition between the two distinct topological states of insulation and ...

Our magnetic topological insulator Hall-bar array enables efficient implementation of reinforcement learning algorithms, such as quantum state preparation, near quantum processors." While previous ...

Several prominent phenomena of condensed matter, exemplified by nonlinear transport, flat-band superconductivity, and ...

The layered Hall effect represents the first clear experimental evidence of the state, a feature bound by the laws of quantum physics, according to Boston College Assistant Professor of Physics Qiong ...
