Researchers demonstrate direct comparison of spin-squeezed optical lattice clocks at record precision level
Optical Lattice Clock at JILA, Boulder. Credit: JILA Although today’s best optical atomic clocks can be used to make extremely precise measurements, they are still limited by the noise from…
Scientists discover quantum oscillations in correlated insulators
Quantum oscillations in correlated insulator at v = -2. Credit: YANG Wei Quantum oscillations (QOs) of conductance in the magnetic field are widely observed in mesoscopic devices thanks to the…
Electron spin measured for the first time
Three perspectives of the surface on which the electrons move. On the left, the experimental result, in the center and on the right the theoretical modeling. The red and blue…
