Two-dimensional (2D) materials, such as graphene or transition metal dichalcogenides, can sometimes be assembled into bilayers with a twist between individual layers. In recent years, many researchers have been investigating ...
A team of theoretical and experimental physicists have designed a new ultra-thin material that they have used to create elusive quantum states. Called one-dimensional Majorana zero energy modes, these quantum states could ...

"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 ...
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 ...
