A general time-to-energy transform of wavepackets. Time-independent wavepacket-Schrödinger and wavepacket-Lippmann—Schwinger equations

摘要: Abstract Recently, new time-independent wavepacket-Schrodinger and wavepacket-Lippmann—Schwinger equations have been derived making use of absorbing potentials. We show that these equations, which are characterized by the occurrence an initial ¢L2-wavepacket source scattered waves, can be gotten without introducing potential. also a powerful method solving based on Chebychev representation causal full Green function, combined with distributed approximating function system Hamiltonian, we present two example applications illustrating approach.
