Physicists have forced light to behave like electrons trapped in a magnetic field, producing a quantized sideways drift that had never been observed in photons before. The experiment, carried out on ...

Mentor: Imran Mirza, Ph.D. In this poster, we review the integer quantum Hall effect for standard electronic systems. We find that the Hall resistance in 2D materials is quantized into fixed values ...

Graphene enables precise carrier-density control via gating, making it an ideal platform for studying electronic interactions. However, sample inhomogeneities often limit access to the low-density ...

Researchers at the University of Würzburg have developed a method that can improve the performance of quantum resistance standards. It's based on a quantum phenomenon called Quantum Anomalous Hall ...

Quantum materials can be loosely defined as materials for which quantum mechanical effects manifest on a macroscopic scale. Two classes of quantum materials are paradigmatic: superconductors, and ...

Purdue University doctoral student Yang Xu, lead author of a new research paper on "topological insulators," an emerging class of materials that could make possible "spintronic" devices and practical ...

What is the Hall Effect? The Hall effect is a fundamental phenomenon in physics that occurs when an electric current flows through a conductor in the presence of a magnetic field perpendicular to the ...
