Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely ...

This publication is essentially a compilation of the lecture notes taken by several people at the introductory course in quantum mechanics given by the authors in conjunction with Los Alamos ...

Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

Over the past decades, the mathematical formulation of physical theories has evolved to provide a unified framework that bridges classical mechanics, quantum mechanics and quantum information theory.

The implications of quantum mechanics suggest reality isn't as solid as we think it is, but physicist David Bohm had a spin ...

A century ago, science went quantum. To celebrate, physicists are throwing a global, year-long party. In 1925, quantum mechanics, the scientific theory that describes the unintuitive rules of physics ...

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...

Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means is up for interpretation. Suppose you want to empty a box. Really, truly ...
