“…Figure 5 shows the time-resolved ion signal for 63S 1/2 at a dc electric field of ε = 267 mV/cm and a fixed delay time of 6 µs. A possible explanation is that the electric field induces nonadiabatic transition by forming energy crossings,and the influence of the dc Stark effect on the nonadiabatic multichannel decay of quasimolecules has been investigated [27]. The other possible reason is that pairs of 63S 1/2 states are energetically degenerate with closer attractive pairs states for certain electric fields, and the electric field leads to l and n mixing between dipole-dipole coupled states.…”

The collisional loss rates of 63S 1/2 Rydberg atoms in cesium magneto-optical trap are measured by using the state-selective pulse field ionization technique and used to investigate the interaction between Rydberg atoms. The collisional loss rate coefficients due to collisions with Rydberg atoms and ground-state atoms are obtained by fitting the experimental data. The results indicate that the large collisional loss mainly comes from the strong long-range interaction between ultracold Rydberg atoms, and the loss rate is significantly increased under a weak electric field.

“…The Coulomb potential frequently appears in studies of nonadiabatic transitions in molecular physics [1,15,19]. Moreover, if one of the levels is degenerate before a molecular collision or an application of a time-dependent field, this degeneracy experiences fan-like spitting, as in Rydberg's atoms due to the Stark effect [20]. Hence, the LZC-model represents an important class of processes in atomic and molecular physics.…”

We derive an exact solution of an explicitly time-dependent multichannel model of quantum mechanical nonadiabatic transitions. In the limit N≫1, where N is the number of states, we find that the survival probability of the initially populated state remains finite despite an almost arbitrary choice of a large number of parameters. This observation proves that quantum mechanical nonadiabatic transitions among a large number of states can effectively keep memory about the initial state of the system. This property can lead to a strongly nonergodic behavior even in the thermodynamic limit of some systems with a broad distribution of coupling constants and the lack of energy conservation.

“…As we have shown in our recent work [17], this is strong evidence that a two-body interaction dominates the dynamics. We show that the multistate nature of the Rydberg atom pair interaction potentials [15,18,19] can be used to explain the observed line broadening while maintaining consistency with the quadratic scaling of the product yield with Rydberg state population. The explanation of the line broadening spectra at high densities requires that a Rydberg atom blockade be taken into account [20,21], but does not require the introduction of more than a two-body interaction between a pair of atoms.…”
