Minimal Lagrangian Surfaces in S 2 × S 2

We deal with the minimal Lagrangian surfaces of the EinsteinKähler surface S × S, studying local geometric properties and showing that they can be locally described as Gauss maps of minimal surfaces in S ⊂ R. We also discuss the second variation of the area and characterize the most relevant examples by their stability behaviour.

Tight Lagrangian surfaces in S 2 × S 2 ∗

We determine all tight Lagrangian surfaces in S 2 × S 2. In particular, globally tight Lagrangian surfaces in S 2 × S 2 are nothing but real forms.

Large - scale relativistic configuration - interaction calculation of the 2 s 2 1 S 0 – 2 s 2 p 3 P 1 intercombination transition in C III

A large-scale, relativistic configuration-interaction ~RCI! method has been developed for precision calculations of transition oscillator strengths. It is based on the no-pair Hamiltonian and employs finite B-spline basis functions. For the 2s S0 –2s2p P1 intercombination transition in berylliumlike carbon, the present RCI expansions reach close to 200 000 configurations, and include all single...

Interference effects in hyperfine induced 2 s 2 s 3 P 0 , 3 P 2 → 2 s 2 1 S 0 transitions of Be - like ions

The hyperfine induced 2s2p P0, P2 → 2s 2 S0 E1 transition probabilities of Be-like ions were calculated using grasp2K based on multi-configuration Dirac-Fock method and HFST packages. It was found that the hyperfine quenching rates are strongly affected by the interference for low-Z Be-like ions, especially for 2s2p P0 → 2s2 S0 transition. In particular, the trends of interference effects with ...
