“…The case of Fr is especially interesting in light of the recent experiments involving trapping of Fr atoms [51] g.s. and 220 eV energy splitting within the parity doublet [11,55] and b) K = unidentified parity partner level [56,12] were made.…”

Collective P-and T-odd moments produced by parity and time invariance violating forces in reflection asymmetric nuclei are considered. The enhanced collective Schiff, electric dipole and octupole moments appear due to the mixing of rotational levels of opposite parity. These moments can exceed singleparticle moments by more than two orders of magnitude. The enhancement is due to the collective nature of the intrinsic moments and the small energy separation between members of parity doublets. In turn these nuclear moments induce enhanced T-and P-odd effects in atoms and molecules. First a simple estimate is given and then a detailed theoretical treatment of the collective T-, P-odd electric moments in reflection asymmetric, odd-mass nuclei is presented and various corrections evaluated. Calculations are performed for octupole deformed long-lived odd-mass isotopes of Rn, Fr, Ra, Ac and Pa and the corresponding atoms. Experiments with such atoms may improve substantially the limits on time reversal violation.

“…A far detuned blue optical dipole trap has the advantage that the externally applied DC electric and magnetic fields, as well as the k of the laser excitation field are decoupled from the light field that provides the trap. We have demonstrated trapping of 1000 210 Fr atoms in a magneto-optical trap [22], a number that we have increased by a factor of ten [23]. We are currently working on improving the number of trapped atoms by using a double MOT system and thus having a much longer trap life-time.…”

“…Similar to other alkali atoms D-lines in Fr atom are used for laser cooling and trapping experiments, which leads to the easy accessibility of this atom for its application in probing new physics of fundamental particles [13][14][15]. Therefore, it is certainly attainable to develop cooling and trapping techniques for the Fr atoms in near future.…”

Magic wavelengths (λmagic) for the 7S 1/2 − 7P 1/2,3/2 transitions (D-lines) in Fr were reported by Dammalapati et al. in [Phys. Rev. A 93, 043407 (2016)]. These λmagic were determined by plotting dynamic polarizabilities (α) of the involved states with the above transitions against a desired range of wavelength. Electric dipole (E1) matrix elements listed in [J. Phys. Chem. Ref. Data 36, 497 (2007)], from the measured lifetimes of the 7P 1/2,3/2 states and from the calculations considering core-polarization effects in the relativistic Hartree-Fock (HFR) method, were used to determine α. However, contributions from core correlation effects and from the E1 matrix elements of the 7P −7S, 7P − 8S and 7P − 6D transitions to α of the 7P states were ignored. In this work, we demonstrate importance of these contributions and improve accuracies of α further by replacing the E1 matrix elements taken from the HFR method by the values obtained employing relativistic coupled-cluster theory. Our static α are found to be in excellent agreement with the other available theoretical results; whereas substituting the E1 matrix elements used by Dammalapati et al. give very small α values for the 7P states. Owing to this, we find disagreement in λmagic reported by Dammalapati et al. for linearly polarized light; especially at wavelengths close to the D-lines and in the infrared region. As a consequence, a λmagic reported at 797.75 nm which was seen supporting a blue detuned trap in their work is now estimated at 771.03 nm and is supporting a red detuned trap. Also, none of our results match with the earlier results for circularly polarized light. Moreover, our static values of α will be very useful for guiding experiments to carry out their measurements.
