Arnol'd, 1998, connexions between disparate parts of mathematics
For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials that were theoriz...
"Our observations, taken together with the observations using ultracold atoms, provide the first demonstration of higher-dimensional quantum Hall physics"
Quantum Hall Effect
Introduction The Quantum Hall Effect is a quantum-mechanical version of the classical Hall effect. The Hall effect involves the generation of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. The Quantum Hall Effect, however, is observed at extremely low temperatures and…

Researchers Demonstrate Three-Dimensional Quantum Hall Effect for the First Time
Researchers Demonstrate Three-Dimensional Quantum Hall Effect for the First Time
The quantum Hall effect (QHE), which was previously known for two-dimensional (2D) systems, was predicted to be possible for three-dimensional (3D) systems by Bertrand Halperin in 1987, but the theory was not proven until recently by researchers from the Singapore University of Technology and Design (SUTD) and their research collaborators from around the globe.
The Hall effect, a fundamental…

Experiments Show The Effects of a Fourth Spatial Dimension
Wow.
By David Nield
We're used to dealing with three physical dimensions and one extra dimension of time as we move through the Universe, but two teams of scientists have shown that a fourth spatial dimension could reach beyond the limits of up and down, left and right, and forwards and backwards.
As you might expect given this is bending the laws of physics, the experiments involved are partly theoretical and very complex, and touch on our old friend quantum mechanics.

WHY WOULD ANY PROFESSOR SUGGEST THIS TO ME?! I CANNOT HANDLE THIS. I WAS JUST INTRIGUED BY A HALL PROBE.
THE START OF THIS BOOK IS ALL "LET'S HAVE A BRIEF REVIEW OF QUANTUM FIELD THEORY" .... I JUST THOUGHT IT WAS MILDLY INTERESTING. WHY AM I READING THIS BOOK AGAIN?!?!?
