Spin-orbit-coupled cold atomic gases are proposed as a model system for observing the signatures of quantum chaos.

A generalized form of the Pauli exclusion principle gives insight into the quantum wave function describing multiple electrons.

Compared to classical solids, the quantum solid helium-4 can undergo a giant plastic deformation that is also reversible.

The demonstration of a single-particle interferometer opens the door to a number of applications, from investigations of gravity to surface impact physics.

The combination of several quantum states that are local can yield a nonlocal state.

Microwave signals in an entangled state can be generated and then spatially separated on a single chip, enabling quantum communication with microwave technology.

Researchers propose how to realize time crystals, structures whose lowest-energy states are periodic both in time and space.

A new optical experiment provides further proof that quantum mechanics is not hiding some classical framework beneath its veneer of context-dependent observations.

Experiments on electron transport across single molecules show evidence of enhancement of the current at higher temperatures due to suppression of destructive quantum interference.

The explanation for why helium doesn’t solidify at low temperatures may be more complicated than previously thought.

Colliding matter waves from a Bose-Einstein condensate violate a relation called the Cauchy-Schwarz inequality, proving that such interactions must be considered quantum mechanically.

Majorana’s geometrical representation of quantum spin as points on a sphere offers an intuitive approach to understanding quantum systems with multiple components.
