Sound typically propagates through a medium via collisions between atoms. But these bumps aren’t always required. Two teams of researchers reveal that sound can travel in a 2D Bose gas—a thin film of ...

What is inside an atom between the nucleus and the electron? Usually there is nothing, but why could there not be other particles too? If the electron orbits the nucleus at a great distance, there is ...

Three-dimensional (3D) antiferromagnets are materials in which magnetic moments of atoms or ions are arranged in a 3D lattice structure with neighboring spins aligned in opposite directions.

However, the most omnipresent Bose gas, blackbody radiation (radiation in thermal equilibrium with the cavity walls) does not show this phase transition. In such systems photons have a vanishing ...

Gauge fields describe the basic interactions between charged particles and are responsible for various emergent topological phases of matter. This concept recently has been further generalized to ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? Bose-Einstein condensates (BECs) are a kind of quantum “magnifying glass” in which ...

Containing fully worked examples and real-world problems, this book first explains the key concepts of statistical and thermal physics and then applies them to a wide variety of phenomena.
