Physicists in Germany have developed a new way of defining the standard unit of electrical resistance. The advantage of the ...

This phenomenon is known as the quantum spin Hall effect. An illustrative example of a spintronics circuit using silver (Ag) to demonstrate spin current manipulation via the Spin Hall Effect. This ...

Physicists have identified an unprecedented quantum phenomenon that allows precise manipulation of electron spin and ...

First, the quantum tunneling effect becomes prominent ... These topological band structures can produce large Berry curvature, which determines the intrinsic spin Hall effect (Xiao et al., 2010; ...

Spin is the intrinsic angular momentum of ... The basis for the new study is the quantum Hall effect. Klaus von Klitzing received the Nobel Prize in Physics in 1985 for its detection.

Their work ("Quantum Spin Hall Effect in Graphene") would usher in a new era of materials science dealing with topological insulators. In two-dimensions, an ideal topological insulator would have ...

Physics: Current Generated by the Quantum Hall Effect Has Additional Magnetic Properties Dec. 17, 2024 — The quantum Hall effect, a fundamental effect in quantum mechanics, not only generates an ...

We numerically study the fractional quantum Hall effect at filling factors = 12=5 and 13/5 (the particle-hole conjugate of 12/5) in high-quality two-dimensional GaAs heterostructures via exact ...

The team's discovery centers around a phenomenon known as the fractional quantum Hall effect, which builds on the classical Hall effect, where a magnetic field is applied to a material with an ...
