We present results of a method for calculating optical pumping rates in 87 Rb, as described in [1]. We use circularly polarised light on the (F g = 2 ↔ F e = 3) transition to populate a stretched angular momentum state in the F g = 2 hyperfine structure level of the ground state. The method is shown to function well for the the studied system....
We present results of a method for calculating optical pumping rates in 87 Rb, as described in [1]. We use light with an impure polarization (i.e. a mixture of σ + , σ − and π light) to populate a stretched angular momentum state in the F g = 2 hyperfine structure level of the ground state. The method is shown to function well for the studied...
Mathematica (v. 11.0.0.0) code for a solution of the 5x5 matrix for optical pumping with circularly polarized (sigma+) light for the D2 transition in Rb-87, Fg=2->Fe=3 line, in the absence of an external magnetic field. The light polarization is contaminated by components of (sigma-) and (pi) polarizations. More generally, the code can be used...
We present results of a method for calculating optical pumping rates in 87 Rb, as described in [1]. We use linearly polarized light on the (F g = 2 ↔ F e = 2) transition to populate an angular momentum state in the F g = 2 hyperfine structure level of the ground state, with magnetic quantum number M g = 0 — that is a clock state. The open decay...
Besides being a source of energy, light can also cool gases of atoms down to the lowest temperatures ever measured, where atomic motion almost stops. The research field of cold atoms has emerged as a multidisciplinary one, highly relevant, e.g., for precision measurements, quantum gases, simulations of many-body physics, and atom optics. In...
We present results of a method for calculating optical pumping rates in 87 Rb, as described in [1]. We use circularly polarized light to populate a stretched angular momentum state in the F g = 2 hyperfine structure level of the ground state. We include in the analysis an applied weak magnetic field. The method is shown to function well for the...
Mathematica (v. 11.0.0.0) code for a solution of the 8x8 matrix for optical pumping with linear polarization for the D2 transition in Rb-87, Fg=2->Fg=2, in the absence of an external magnetic field. In order to avoid optical depumping to Fg=1, repumping light on the transition Fg=1->Fe=2 has been added.
We present results of a method for calculating optical pumping rates in 87 Rb, as described in [1]. We use a mixture of circularly polarised light (σ + and σ −) on the (F g = 1 ↔ F e = 0) transition to populate an angular momentum state in the F g = 1 hyperfine structure level of the ground state, with magnetic quantum number M g = 0 — that is...

We have evaluated the isotope shift (IS) constants of the first five low-lying fine-structure states of the singly charged calcium ion (Ca II) by adopting a finite-field (FF) approach in the relativistic coupled-cluster (RCC), a method developed by us and by using a code also developed by us. A similar previous calculation using singles and...
