Double Poles and Nonexponential Decays in Atomic Physics

K. E. Lassila, Vesa Ruuskanen

Published Aug 29, 1966• 37 citations
Publisher

Abstract

Atomic resonance fluorescence is examined as a scattering problem, and Goldberger-Watson double poles are found to occur in situations producible in the laboratory. Systematic study of this effect and associated nonexponential decay thus appears possible.

Full-time nonexponential decay in double-barrier quantum structures

Gastón García‐Calderón, Jorge Villavicencio

We examine an analytical expression for the survival probability for the time evolution of quantum decay to discuss a regime where quantum decay is nonexponential at all times. We find that the interference between the exponential and nonexponential terms of the survival amplitude modifies the usual exponential decay regime in systems where the ratio of the resonance energy to the decay width is less than 0.3. We suggest that such a regime could be observed in semiconductor double-barrier resonant quantum structures with appropriate parameters.

Time asymmetry, nonexponential decay, and complex eigenvalues in the theory and computation of resonance states

Cleanthes A. Nicolaides

Abstract Stationary‐state quantum mechanics presents no difficulties in defining and computing discrete excited states because they obey the rules established in the properties of Hilbert space. However, when this idealization has to be abandoned to formulate a theory of excited states dissipating into a continuous spectrum, the problem acquires additional interest in many fields of physics. In this article, the theory of resonances in the continuous spectrum is formulated as a problem of decaying states, whose treatment can entail time‐dependent as well as energy‐dependent theories. The author focuses on certain formal and computational issues and discusses their application to polyelectronic atomic states. It is argued that crucial to the theory is the understanding and computation of a multiparticle localized wavepacket, Ψ0, at t = 0, having a real energy E0. Assuming this as the origin, without memory of the excitation process, the author discusses aspects of time‐dependent dynamics, for t ≈ 0 as well as for t → ∞, and the possible significance of nonexponential decay in the understanding of time asymmetry. Also discussed is the origin of the complex eigenvalue Schrödinger equation (CESE) satisfied by resonance states and the state‐specific methodology for its solution. The complex eigenvalue drives the decay exponentially, with a rate Γ, to a good approximation. It is connected to E0 via analytic continuation of the complex self‐energy function, A(z), (z is complex), into the second Riemann sheet, or, via the imposition of outgoing wave boundary conditions on the stationary state Schrödinger equation satisfied by the Fano standing wave superposition in the vicinity of E0. If the nondecay amplitude, G(t), is evaluated by inserting the unit operator I = ∫dE|E><E| G(t) = < Ψ0|e−iHt|Ψ0 >, then the resulting spectral function is real, g(E) =|<Ψ0|E>|2, and does not differentiate between positive and negative times. The introduction of time asymmetry, which is associated with irreversibility, is achieved by starting from < Ψ0|θ(t)e−iHt|Ψ0 >, where θ(t) is the step function at the discontinuity point t = 0. In this case, the spectral function is complex. Within the range of validity of exponential decay, the complex spectral function is the same as the coefficient of Ψ0 in the theory of the CESE. A calculation of G(t) using the simple pole approximation and the constraints that t > 0 and E > 0 results in a nonexponential decay (NED) correction for t ≫ 1/Γ that is different than when a real g(E) is used, representing the contribution of both “in” and “out” states. Earlier formal and computational work has shown that resonance states close to threshold are good candidates for NED to acquire nonnegligible magnitude. In this context, a pump‐probe laser experiment in atomic physics is proposed, using as a paradigm the He− 1s2p2 4P shape resonance. © 2002 Wiley Periodicals, Inc. Int J Quantum Chem, 2002

Resonances from non-Hermitian quantum mechanical calculations

Nimrod Moiseyev

The Hermitian properties of the Hamiltonian are related not only to the operator itself but also to the functions on which it acts. Hermitian Hamiltonians operate on functions in the L 2 Hilbert space which correspond to boundary conditions which vanish at infinity. In this chapter, in order to move into the non-Hermitian domain, we will impose on the solutions to the time-independent Schrödinger equation (TISE) different boundary conditions which lead to solutions which can be associated with different types of the complex poles of the scattering matrix. These solutions will contain information which was not available within the scope of functions in L 2 . By imposing outgoing boundary conditions on the eigenfunctions of the timeindependent Hamiltonian complex eigenvalues, E res = ε − (i/2)Г, are obtained. These complex energies are associated with decaying resonance states which were discussed in the previous two chapters. The bound states (if they exist) appear as real eigenvalues since they result from exactly such outgoing boundary conditions which appear under the threshold energy. When incoming boundary conditions are imposed two kind of solution are obtained. One type of solution is the complex conjugates of the decay resonance solutions mentioned above. In scattering theory text books (see Taylor for example) the physical resonance solutions are associated with the poles of the scattering matrix which are embedded in the lower half of the complex energy plane. However, in nuclear physics the complex poles embedded in the upper half of the complex energy plane, so-called virtual states , are denoted as capture resonances .
