Rachna Arora Walk into any Class 11 Physics class and you will instantly see where both degrees begin. The teacher draws a ...

For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without ...

Royalty-free licenses let you pay once to use copyrighted images and video clips in personal and commercial projects on an ongoing basis without requiring additional payments each time you use that ...

Illustration of a polaron in a crystal: the central bright sphere is the charge carrier, distorting the surrounding lattice. The wavy lines represent high-order Feynman diagrams for the ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

ABSTRACT: We establish quantum circuit complexity as a fundamental physical observable and prove that it satisfies an uncertainty relation with energy, analogous to Heisenberg’s canonical uncertainty ...

ABSTRACT: This work proposes quantum circuit complexity—the minimal number of elementary operations needed to implement a quantum transformation—be established as a legitimate physical observable. We ...

The 16-part course, currently in its pilot phase, is catered to high school students but available to anyone interested in learning about the fundamental questions in particle physics. Jeff Wiener ...

Experiments and simulations in particle physics are probing the critical point in the Quantum Chromodynamics phase diagram to detect and understand phase changes in quark matter, utilizing advanced ...
