Lifetime of the Wannier-Stark resonances and perturbation theory
نویسندگان
چکیده
We consider the small field asymptotics of the ladder lifetime for a single ladder model. Using the convergent perturbation series, we prove that the behavior of the lifetime computed by means of the Fermi Golden Rule is proportional to the correct one with the factor ( π 3 )2 . The relation with usual adiabatic problems is briefly discussed.

Wannier-bloch Oscillators
We consider a Wannier-Stark problem for small eld f in the one-ladder case. We prove that a generical rst band state is a metastable state (Wannier-Bloch oscillator) with the lifetime determined by the imaginary part of the Wannier-Stark ladder. The innnite resonances of the ladder cause Bloch oscillations as a global beating eeect. For an adiabatic time = ft large enough, but much smaller than...

متن کاملCoherent delocalization of atomic wave packets in driven lattice potentials.
Atomic wave packets loaded into a phase-modulated vertical optical-lattice potential exhibit a coherent delocalization dynamics arising from intraband transitions among Wannier-Stark levels. Wannier-Stark intraband transitions are here observed by monitoring the in situ wave-packet extent. By varying the modulation frequency, we find resonances at integer multiples of the Bloch frequency. The r...
متن کاملPerturbation Theory and Atomic Resonances Since Schrödinger’s Time
Abstract. Quantum theory makes a sharp distinction between bound states and scattering states, the former associated with point spectrum and the latter with continuous spectrum. Resonances associated with quasi-stationary states bridge this distinction, and have posed mathematical challenges since the beginning of the Schrödinger theory. Here the development of mathematical aspects of resonance...
متن کاملHigh Order Horizontal Resonances in the Beam-Beam Interaction
This paper studies the characteristics of horizontal resonances excited by the beam-beam interaction. First order perturbation theory and simulations show that high order horizontal resonances are exceptionally strong at large amplitudes. The orders of these resonances are so high that they may mistakenly be ignored, and they can result in bad lifetime.
