The thermal hall effect (THE) is a physical phenomenon characterized by tiny transverse temperature differences occurring in a material when a thermal current passes through it and a perpendicular magnetic field is applied ...
A research team from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the University of Salerno in Italy has discovered that thin films of elemental bismuth exhibit the so-called non-linear Hall effect, which could be ...
In a novel experiment, physicists have observed long range quantum coherence effects due to Aharonov-Bohm interference in a topological insulator-based device. This finding opens up a new realm of possibilities for the future ...
If the fractional quantum Hall regime were a series of highways, these highways would have either two or four lanes. The flow of the two-flux or four-flux composite fermions, like automobiles in this two- to four-flux composite ...
The electron is the basic unit of electricity, as it carries a single negative charge. This is what we're taught in high school physics, and it is overwhelmingly the case in most materials in nature.
A significant breakthrough has been achieved by quantum physicists from Dresden and Würzburg. They've created a semiconductor device where exceptional robustness and sensitivity are ensured by a quantum phenomenon. This ...
A team at HZB has developed a new measurement method that, for the first time, accurately detects tiny temperature differences in the range of 100 microKelvin in the thermal Hall effect. Previously, these temperature differences ...
In the ever-evolving landscape of condensed matter physics, a recent breakthrough has emerged from the collaborative efforts of researchers at the Peter Grünberg Institute (PGI-1), École Polytechnique Fédérale de Lausanne, ...
Within atomic and laser physics communities, scientist John "Jan" Hall has become a key figure in the history of laser frequency stabilization and precision measurement using lasers. Hall's work revolved around understanding ...
Spintronic devices are electronic devices that utilize the spin of electrons (an intrinsic form of angular momentum possessed by the electron) to achieve high-speed processing and low-cost data storage. In this regard, spin-transfer ...
