When exposed to stress and strain, materials can display a wide range of different properties. By using sound waves, scientists have begun to explore fundamental stress behaviors in a crystalline ...

To study the interactions between electrons in a material, physicists have come up with a number of tricks over the years. These interactions are interesting, among other things, because they lead ...

The Wigner crystal lattice. Image: Yen-Chen Tsui and team, Princeton University Wigner theorized that this quantum phase of electrons would occur due to the particles’ mutual repulsion, not in ...
