Multipolar theory of blackbody radiation shift of atomic energy levels and its implications for optical lattice clocks
Blackbody radiation BBR shifts of the P0S0 clock transition in the divalent atoms Mg, Ca, Sr, and Yb are evaluated. The dominant electric-dipole contributions are computed using accurate relativistic many-body techniques of atomic structure. At room temperatures, the resulting uncertainties in the E1 BBR shifts are large and substantially affect the projected 10−18 fractional accuracy of the op...
متن کاملGhost Imaging with Blackbody Radiation
Abstract We present a theoretical study of ghost imaging by using blackbody radiation source. A Gaussian thin lens equation for the ghost imaging, which depends on both paths, is derived. The dependences of the visibility and quality of the image on the transverse size and temperature of the blackbody are studied. The main differences between the ghost imaging by using the blackbody radiation a...
متن کاملComputational Blackbody Radiation
Maxwell’s equations represent a culmination of classical mathematical physics by offering a compact mathematical formulation of all of electromagnetics including the propagation of light and radiation, as electromagnetic waves. But like in a Greek tragedy, the success of Maxwell’s equations prepared for the collapse of classical mathematical physics and the rise of modern physics based on a con...
متن کاملYtterbium in quantum gases and atomic clocks: van der Waals interactions and blackbody shifts.
We evaluated the C(6) coefficients of Yb-Yb, Yb-alkali, and Yb-group II van der Waals interactions with 2% uncertainty. The only existing experimental result for such quantities is for the Yb-Yb dimer. Our value, C(6)=1929(39) a.u., is in excellent agreement with the recent experimental determination of 1932(35) a.u. We have also developed a new approach for the calculation of the dynamic corre...
متن کاملRydberg spectroscopy in an optical lattice: blackbody thermometry for atomic clocks.
We show that optical spectroscopy of Rydberg states can provide accurate in situ thermometry at room temperature. Transitions from a metastable state to Rydberg states with principal quantum numbers of 25-30 have 200 times larger fractional frequency sensitivities to blackbody radiation than the strontium clock transition. We demonstrate that magic-wavelength lattices exist for both strontium a...
