• Abstract: The interaction of strong pulsed femtosecond laser field with atoms having three equivalent electrons in the outer shell ($p^3$ configuration, e.g. nitrogen) is studied via numerical integration of a time-dependent Schr\"{o}dinger equation on a grid approach. Single, double and triple ionization yields originating from a completely antisymmetric wave function are calculated and extracted using a restricted-geometry model with the soft-core potential and three active electrons. The direct triple ionization channel is found to produce a larger yield than the channel connected with single and then direct double ionization. Compared against earlier results investigating the $n s^ 2 n p^1$ configuration, we propose that the differences found here might in fact be accessible through electron's momentum distribution.

  The triplet contribution is computed to the 1 and 2 states of the He atom. The no-pair Dirac-Coulomb-Breit wave equation is converged within a sub-parts-per-billion relative precision. The fine-structure constant dependence of the triplet sector contribution to the variational energy is $alpha4E_texth$ at leading order.

• Charged ultralong-range Rydberg trimers [0.0]
  Long-range ion-Rydberg molecules can be divided into two families of states, which are characterised by their unique electronic structures. We predict that in both cases these diatomic molecular states can bind additional ground state atoms lying within the orbit of the Rydberg electron. The predicted trimer binding energies and excitation series are distinct enough to be observed using current experimental techniques.

  We study model atoms with three active electrons interacting with strong pulsed radiation, using an ab-initio time-dependent Schr"odinger equation on a grid. We show that significant differences are obtained between model Neon and Nitrogen atoms. These differences are traced back to the different symmetries of the electronic wavefunctions, and directly related to the different initial state spin components.

  Motivated by experiments in 1D electron channels written on the $mathrmLaAlO_3$/$mathrmSrTiO_3$ interface, we analyse how the presence of different forms of spin-orbit coupling can enhance electron pairing in 1D waveguides. We show how the intrinsic Rashba SOC felt by electrons at interfaces such as $mathrmLaAlO_3$/$mathrmSrTiO_3$ can be reduced when they are confined in 1D. We discuss how SOC can be engineered, and show using a mean

  We consider a 2d dipolar system, $d=2$, with the generalized dipole-dipole interaction $sim r-a$, and the power $a$ controlled experimentally in trapped-ion or Rydberg-atom systems. We show that the spatially homogeneous tilt $beta$ of the dipoles giving rise to the anisotropic dipole exchange leads to the non-trivial reentrant localization beyond the locator expansion.
