It's based on a quantum phenomenon called Quantum Anomalous Hall effect. The precise measurement of electrical resistance is essential in industrial production or electronics—for example ...

Jain, Professor of Physics at Penn State University, has been awarded the prestigious 2025 Wolf Prize in Physics. Jain shares ...

In the fractional quantum Hall effect, these steps become even more peculiar, increasing by only fractional amounts—carrying a fraction of an electron's charge.

Indian American physicist predicted a new class of exotic particles which could be integral to high-performance electronics ...

Light was long considered to be a wave, exhibiting the phenomenon of interference in which ripples like those in water waves ...

Once completed, the expanded Duffield Hall will be 300,000 square feet and the gateway to the tech-centric southern edge of ...

Quantum Hall is the quantum-level version of the Hall effect: a voltage produced as electrons flow through a magnetic field. In two-dimensional materials and at low temperatures the quantum ...

A counterexample is the two-dimensional integer quantum Hall state, which has an energy gap due to the quantization of electronic states in a magnetic field. Despite the gap, this state is not a ...
