Lineshape-asymmetry-caused shift in atomic interferometers
V. I. Yudin, O. N. Prudnikov, A. V. Taichenachev +7
We investigate the shift caused by asymmetry of spectroscopic lineshape in atomic interferometers, which has not previously been discussed in the scientific literature. This asymme…
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…
Roadmap towards the redefinition of the second
N. Dimarcq, M. Gertsvolf, G. Mileti +34
This paper outlines the roadmap towards the redefinition of the second, which was recently updated by the CCTF Task Force created by the CCTF in 2020. The main achievements and the…
Comparison of different estimates of the accuracy of forecasts of the Earth's rotation parameters
Z. M. Malkin, V. M. Tissen
Improvement of the prediction accuracy of the Earth's rotation parameters (ERP) is one of the main problems of applied astrometry. In order to solve this problem, various approache…
Probe field ellipticity-induced shift in an atomic clock
V. I. Yudin, A. V. Taichenachev, O. N. Prudnikov +5
We investigate the probe field induced shift for atomic lattice-based and ion-trap clocks, which can be considered as a near resonant ac-Stark shift, connected to the Zeeman struct…
Majority carrier type inversion in FeSe family and "doped semimetal" scheme in iron-based superconductors
Y. A. Ovchenkov, D. A. Chareev, V. A. Kulbachinskii +5
The field and temperature dependencies of the longitudinal and Hall resistivity have been studied for high-quality FeSeS (x up to 0.14) single crystals. Quasiclas…
Magnetotransport properties of FeSe in fields up to 50T
Y. A. Ovchenkov, D. A. Chareev, V. A. Kulbachinskii +5
Magnetotransport properties of the high-quality FeSe crystal, measured in a wide temperature range and in magnetic fields up to 50 T, show the symmetry of the main holelike and ele…
An Exo-Jupiter Candidate in the Eclipsing Binary FL Lyr
V. S. Kozyreva, A. I. Bogomazov, B. P. Demkov +2
Light curves of the eclipsing binary FL Lyr acquired by the Kepler space telescope are analyzed. Eclipse timing measurements for FL Lyr testify to the presence of a third body in t…
Frequency Light Shifts Caused by the Effects of Quantization of Atomic Motion in an Optical Lattice
A. V. Taichenachev, V. I. Yudin, V. D. Ovsiannikov +1
Frequency light shifts resulting from the localization effects and effects of the quantization of translational atomic motion in an optical lattice is studied for a forbidden optic…
Trapping of Neutral Mercury Atoms and Prospects for Optical Lattice Clocks
H. Hachisu, K. Miyagishi, S. G. Porsev +5
We report a vapor-cell magneto-optical trapping of Hg isotopes on the intercombination transition. Six abundant isotopes, including four bosons and two fermions,…
Optical Lattice Polarization Effects on Hyperpolarizability of Atomic Clock Transitions
A. V. Taichenachev, V. I. Yudin, V. D. Ovsiannikov +1
The light-induced frequency shift due to the hyperpolarizability (i.e. terms of second-order in intensity) is studied for a forbidden optical transition, =0=0. A simple…
Vacuum Einstein Equations in Terms of Curvature Forms
Yuri N. Obukhov, Sergey I. Tertychniy
A closed explicit representation of the vacuum Einstein equations in terms of components of curvature 2-forms is given. The discussion is restricted to the case of non-vanishing cu…
Hyperelliptic Kleinian functions and applications
Victor Buchstaber, Victor Enolskii, Dmitri Leykin
We develop the theory of hyperelliptic Kleinian functions. As applications we consider construction of the explicit matrix realization of the hyperelliptic Kummer varieties, differ…
