A Chinese-Australian collaboration has demonstrated for the first time that interlayer coupling in a van der Waals (vdW) material can be largely modulated by a protonic gate, which inject protons to devices from an ionic ...
An international team led by researchers at Princeton University has uncovered a new class of magnet that exhibits novel quantum effects that extend to room temperature.
A team of Brown University physicists has developed a new type of compact, ultra-sensitive magnetometer. The new device could be useful in a variety of applications involving weak magnetic fields, the researchers say.
The Quantum Hall effect (QHE) is one of the most important discoveries in physical sciences. Due to the one-dimensional (1-D) dissipationless edge states, QHE exhibits exotic transport properties with quantized Hall resistance ...
Nontrivial band topology can combine with magnetic order in a magnetic topological insulator to produce exotic states of matter such as quantum anomalous Hall (QAH) insulators and axion insulators. An aim of condensed matter ...
The quantum anomalous Hall (QAH) effect can combine topology and magnetism to produce precisely quantized Hall resistance at zero magnetic field (an environment carefully screened from magnetic fields). In a recent report ...
A 2017 report of the discovery of a particular kind of Majorana fermion—the chiral Majorana fermion, referred to as the "angel particle"—is likely a false alarm, according to new research. Majorana fermions are enigmatic ...
New experiments with magnetically doped topological insulators at BESSY II have revealed possible methods of lossless signal transmission that involve a surprising self-organization phenomenon. In the future, it might be ...
Since 2016, a team of MIT researchers consisting of graduate students Linda Ye and Min Gu Kang, associate professor of physics Joseph G. Checkelsky, and Class of 1947 Career Development Assistant Professor of Physics Riccardo ...
Heterostructures with magnetism and topology (geometry) are promising materials to realize exotic topological quantum states. However, such materials are challenging to engineer or synthesize. In a new report on Science Advances, ...
