Probing electronic radial wave packets using impulsive momentum retrieval
نویسندگان
چکیده
Subpicosecond half-cycle pulses and a single-shot imaging detector have been used to monitor the evolution of electronic radial wave packets in calcium. The time-dependent momentum-space probability distribution is obtained using the impulsive momentum retrieval �IMR� method. The measured distributions are compared to the results of quantum and classical simulations allowing a comprehensive evaluation of the benefits and limitations of the IMR method.

Creating and probing electronic wave packets using half-cycle pulses.
Ultrashort, nearly unipolar electric field pulses are used to produce novel dynamic states in Rydberg atoms. A single 500 fsec field pulse redistributes essentially all of the population from a single stationary Rydberg state to hundreds of different final states. The dynamic evolution of the nonstationary wave packet is monitored using a second, time-delayed pulse. The time-dependent momentum-...
متن کاملExact results for ‘ bouncing ’ Gaussian wave packets
We consider time-dependent Gaussian wave packet solutions of the Schrödinger equation (with arbitrary initial central position, x0, and momentum, p0, for an otherwise free-particle, but with an infinite wall at x = 0, so-called bouncing wave packets. We show how difference or mirror solutions of the form ψ(x, t)−ψ(−x, t) can, in this case, be normalized exactly, allowing for the evaluation of a...
متن کاملAttosecond light pulses for probing two-electron dynamics of helium in the time domain.
Using attosecond light pulses to doubly ionize a two-electron wave packet of helium, we showed that the time-resolved correlated motion of the two electrons can be probed by measuring their six-dimensional momentum distributions. For simple wave packets, we showed that the measured momenta, when analyzed in appropriate coordinates, can reveal the stretching, the rotational, and the bending vibr...
متن کاملComplete view of Stark wave-packet evolution
Picosecond laser pulses have been used to produce Rydberg wave packets in calcium atoms in the presence of a strong static electric field. The dynamics of the Stark wave packets have been observed by measuring the momentum-space probability distribution as a function of time. The full precession of the electronic orbital angular momentum, the appearance of a large-amplitude, linear oscillation ...
متن کاملSpin-Orbit Entanglement in Time Evolution of Radial Wave Packets in Hydrogenic Systems
Time evolution of radial wave packets built from the eigenstates of Dirac equation for a hydrogenic systems is considered. Radial wave packets are constructed from the states of different n quantum number and the same lowest angular momentum. In general they exhibit a kind of breathing motion with dispersion and (partial) revivals. Calculations show that for some particular preparations of the ...
