Theory of composite Ramsey sequences of radiofrequency pulses beyond the rotating wave approximation
V. I. Yudin, O. N. Prudnikov, A. V. Taichenachev +3
We develop a theory of composite Ramsey sequences of rf pulses interacting with the Zeeman structure at the long-lived atomic level, beyond the rotating wave approximation. Such se…

Optical clock based on two-photon spectroscopy of the nuclear transition in ion Th in a monochromatic field
V. I. Yudin, A. V. Taichenachev, O. N. Prudnikov +4
For the isotope Th we investigate the possibility of two-photon laser spectroscopy of the nuclear clock transition (148.38 nm) using intense monochromatic laser field at tw…

Ultrastable Optical Clock with Neutral Atoms in an Engineered Light Shift Trap
Hidetoshi Katori, Masao Takamoto, V. G. Pal'chikov +1
An ultrastable optical clock based on neutral atoms trapped in an optical lattice is proposed. Complete control over the light shift is achieved by employing the $5s^2 {}^1S_0 \to…
