I began graduate study in 1975, the midpoint of the first 100 years of quantum mechanics, 50 years ago and 50 years after the ...

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 ...

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 ...

This quantum Hall effect cannot be observed in conventional semiconductors above about 30 K because thermal fluctuations wash out the delicate quantum effects that are responsible for it.

Jain was named the 2025 winner alongside fellow physicists Mordehai “Moty” Heiblum, who “pioneered experimental verification of these exotic particles,” and James Eisenstein, who “co-discovered the ...

Jain, Professor of Physics at Penn State University, has been awarded the prestigious 2025 Wolf Prize in Physics. Jain shares this honor with two fellow physicists, Mordehai “Moty” Heiblum and James ...
