When electrons move through a disordered material, they zigzag between imperfections. If there is enough disorder, the electrons can become trapped, inhibiting the material’s ability to conduct ...
However, Weld pointed out, while the interacting disordered quantum system was absorbing energy, it was doing so at a much slower rate than would a classical system. “What we’re seeing is something ...

Uncovering the physics of how electrons screen against conductivity-killer in organic semiconductors
What is a Fermi Liquid? A Fermi liquid is a theoretical model that describes the behavior of interacting electrons in metals and other condensed matter systems at low temperatures. It is based on the ...
Physicists have long relied on the idea that electrons behave like tiny particles zipping through materials, even though quantum physics says their exact position is fundamentally uncertain. Now, ...
Let's think about what physics is and what topics are covered in an introductory physics course.
Physics is built on a foundation of math and it seeks to explain all phenomena in the universe. It forms the basis for other sciences like chemistry and biology. Physics uses simple yet elegant math to describe complex phenomena, from galaxies to biological systems. It's about understanding and predicting the universe's complexity based on simple ideas.
Welcome to AP®︎/College Physics 1! In AP Physics 1, you'll learn algebra-based classical mechanics. To make sure you’re prepared with the fundamentals, we recommend completing high school physics before diving into AP Physics 1.
Khan Academy offers free, world-class education in physics, covering forces and motion topics.
