The all-optical switch is a kind of device that controls light with light, which is the fundamental building block of modern optical communications and information processing. Creating an efficient, ultrafast, and compact ...
Materials that exhibit topological phases can be classified by their dimensionality, symmetries and topological invariants to form conductive-edge states with peculiar transport and spin properties. For example, the quantum ...
Among the most exciting challenges in modern physics is the identification of the neutrino mass ordering. Physicists from the Cluster of Excellence PRISMA+ at Johannes Gutenberg University Mainz (JGU) play a leading role ...
Topological superconductors, with bulk superconducting gap and Majorana fermion states on the surface or edge, are one of the most sought after quantum materials. Topological superconductivity is of fundamental importance ...
A research group from Zhejiang University in China has found that the noncentrosymmetric compound CaPtAs is a superconductor, which shows evidence of unconventional properties. This compound provides a new opportunity for ...
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 ...
"Powering a topological superconductor using a time crystal gives you more than the sum of its parts," says Jason Alicea, a researcher at California Institute of Technology (Caltech) in the US. The discovery of topological ...
A new research study at the Institute of Electronic Structure and Lasers (IESL) of the Foundation for Research and Technology-Hellas (FORTH) finds that minute crystals, many thousand times smaller than a particle of dust, ...
In a new report on Science Advances, Chen Fang and Liang Fu from the Beijing National Laboratory for Condensed Matter Physics in China, Kavli Institute for Theoretical Sciences and the Department of Physics, Massachusetts ...
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 ...
