Blackbody radiation shift for the 1S0--3P0 optical clock transition in zinc and cadmium atoms
Abstract
Black-body radiation (BBR) shifts of 3\!P0-1\!S0 clock transition in divalent atoms Cd and Zn are evaluated using accurate relativistic many-body techniques of atomic structure. Static polarizabilities of the clock levels and relevant electric-dipole matrix elements are computed. We also present a comparative overview of the BBR shifts in optical clocks based on neutral divalent atoms trapped in optical lattices.
