Imaging the Wigner crystal state in a new type of quantum material
In some solid materials under specific conditions, mutual Coulomb interactions shape electrons into many-body correlated states, such as Wigner crystals, which are essentially solids made of electrons. So far, the Wigner ...
Optical atomic clocks poised to redefine how the world measures seconds
Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University worked with the National ...
