Hamiltonian approach for the wave packet dynamics: Beyond Gaussian wave functions
It is well known that the Gaussian wave packet dynamics can be written in terms of Hamilton equations in the extended phase space that is twice as large as in the corresponding classical system. We construct several generalizations of this approach that include non-Gausssian wave packets. These generalizations lead to the further extension of the phase space while retaining the Hamilton structu...
متن کاملExtended Gaussian wave packet dynamics
Wave packet dynamics has exposed interesting new phenomena in several fields. In femto-chemistry [1,2] we are now able to time-resolve chemical processes and also observe effects such as the breakup and revival of wave packets [3]. In atom optics wave packets are used to model matter waves [4] and electron wave packets are seen in the dynamics of Rydberg atoms [5]. The numerical modelling of wa...
متن کاملGaussian Wave Packet Dynamics in the Diamagnetic H-Atom
The method of Gaussian wave packet (GWP) propagation introduced by Heller is a popular tool for doing time dependent quantum mechanical calculations in particular in molecular and in nuclear physics. We show that this method is also applicable to atomic systems. We concentrate on the H-atom in a strong magnetic field, where a well-known regularization is used to remove the singularity. The Coul...
متن کاملGeneralized Gaussian wave packet dynamics: Integrable and chaotic systems.
The ultimate semiclassical wave packet propagation technique is a complex, time-dependent Wentzel-Kramers-Brillouin method known as generalized Gaussian wave packet dynamics (GGWPD). It requires overcoming many technical difficulties in order to be carried out fully in practice. In its place roughly twenty years ago, linearized wave packet dynamics was generalized to methods that include sets o...
متن کاملNew physical wavelet ’ Gaussian Wave Packet ’
An exact solution of the homogeneous wave equation which was found previously is treated from the point of view of the continuous wavelet analysis (CWA). Time being a fixed parameter the solution yields a new multidimensional mother wavelet for the CWA. Both the wavelet and its Fourier transform are given with explicit formulas and are exponentially localized. The wavelet is directional. The wi...
