Hydrogen atom in crossed external fields reexemined by the moment method
نویسنده
چکیده
Recurrence relations of perturbation theory for hydrogen ground state are obtained. With their aid polarizabilities in constant perpendicular electric and magnetic fields are computed up to 80th order. The high orders asymptotic is compared with its quasiclassical estimate. For the case of arbitrary mutual orientation of external fields a general sixth order formula is given. E-mail: [email protected] E-mail: [email protected]

Fictitious time wave packet dynamics: The hydrogen atom in external fields
In the preceding paper [T. Fabčič et al., preprint] “restricted Gaussian wave packets” were introduced for the regularized Coulomb problem in the four-dimensional Kustaanheimo-Stiefel coordinates, and their exact time propagation was derived analytically in a fictitious time variable. We now establish the Gaussian wave packet method for the hydrogen atom in static external fields. A superpositi...

متن کاملHydrogen Adsorption on (5,0) and (3,3) Na-decorated BNNTs
The storage capacity of hydrogen on Na-decorated born nitride nanotubes (BNNTs) is investigated by using density functional theory within Quantum Espresso and Gaussian 09. The results obtained predict that a single Na atom tends to occupy above the central region of the hexagonal rings in (5,0) and (3,3) BNNT structures with a binding energy of -2.67 and -4.28 eV/Na-atom respectively. When a si...
متن کاملSemiclassical quantization of the hydrogen atom in crossed electric and magnetic fields
The S-matrix theory formulation of closed-orbit theory recently proposed by Granger and Greene is extended to atoms in crossed electric and magnetic fields. We present a semiclassical quantization of the hydrogen atom in crossed fields, which succeeds in resolving individual lines in the spectrum, but is restricted to the strongest lines of each n manifold. By means of a detailed semiclassical ...
متن کاملHydrogen atom in a magnetic field: quadrupole moment
Quadrupole moment of the hydrogen atom in a magnetic field B = 0– 4.414×10 G is calculated by two different methods. The first method is variational based on a single trial function. The second method deals with a solution of the Schrödinger equation in a form of a linear combination of the Landau orbitals.
