This is a derivative of the quantum Hall state of matter. Quantum anomalous Hall state: A state which has a quantized Hall resistance even in the absence of external magnetic field. Topological insulator: a material whose interior behaves as an electrical insulator while its surface behaves as an electrical conductor.
In quantum physics, a quantum state is a mathematical entity that embodies the knowledge of a quantum system. ... choosing one of them is a matter of convention.
A quantum Hall state gives rise to quantized Hall voltage measured in the direction perpendicular to the current flow. A quantum spin Hall state is a theoretical phase that may pave the way for the development of electronic devices that dissipate less energy and generate less heat. This is a derivation of the Quantum Hall state of matter.
The field equations of condensed matter physics are remarkably similar to those of high energy particle physics. As a result, much of the theory of particle physics applies to condensed matter physics as well; in particular, there are a selection of field excitations, called quasi-particles, that can be created and explored. These include:
In physics, topological order [1] describes a state or phase of matter that arises in quantum mechanics. Whereas classical phases of matter such as gases and solids correspond to microscopic patterns in the spatial arrangement of particles, topological orders correspond to patterns of long-range quantum entanglement. [2]
A state which can be represented as a wave function / ket in Hilbert space / solution of Schrödinger equation is called pure state. See "mixed state". Quantum numbers a way of representing a state by several numbers, which corresponds to a complete set of commuting observables.
A particularly important discovery of the quantum theory is the uncertainty principle, enunciated by Heisenberg in 1927, which places an absolute theoretical limit on the accuracy of certain measurements; as a result, the assumption by earlier scientists that the physical state of a system could be measured exactly and used to predict future ...
