Physicists demonstrate parity anomaly in a topological insulator

Experimental and theoretical physicists from the Würzburg Institute for Topological Insulators have observed a re-entrant quantum Hall effect in a mercury telluride device and have identified it as a signature of parity ...

Compact accelerator technology achieves major energy milestone

Particle accelerators hold great potential for semiconductor applications, medical imaging and therapy, and research in materials, energy and medicine. But conventional accelerators require plenty of elbow room—kilometers—making ...
