Creation of double-well potentials in a surface-electrode trap towards a nanofriction model emulator
U. Tanaka, M. Nakamura, K. Hayasaka +3
We demonstrate a microfabricated surface-electrode ion trap that is applicable as a nanofriction emulator and studies of many-body dynamics of interacting systems. The trap enables…

Testing the stability of fundamental constants with the 199Hg+ single-ion optical clock
S. Bize, S. A. Diddams, U. Tanaka +10
Over a two-year duration, we have compared the frequency of the 199Hg+ 5d106s 2S 1/2 (F=0)<-> 5d9 6s2 2D 5/2 (F=2) electric-quadrupole transition at 282 nm with the frequency of th…
