Besides serving as a frequency counter or clockwork, an optical frequency comb can be
used directly for spectroscopy, thus the name Direct Frequency Comb Spectroscopy (DFCS) …

We have constructed an automated learning apparatus to control quantum systems. By
directing intense shaped ultrafast laser pulses into a variety of samples and using a …

Advances in Quantum Chemistry presents surveys of current topics in this rapidly
develo** field that has emerged at the cross section of the historically established areas of …

We propose and experimentally demonstrate the method of population transfer by piecewise
adiabatic passage between two quantum states. Coherent excitation of a two-level system …

We present a general and highly efficient scheme for performing narrow-band Raman
transitions between molecular vibrational levels using a coherent train of weak pump-dump …

Quantum control originated in the mid-1980s as a set of different laser schemes designed to
manipulate chemical reactions and excite the molecule in specific quantum states. In the last …

We demonstrate how structured decompositions of unitary operators can be employed to
derive control schemes for finite-level quantum systems that require only sequences of …

Coherent control employing a broadband excitation is applied to a branching reaction in the
excited state. In a weak field for an isolated molecule, a control objective is only frequency …

We develop a method for executing robust and selective transfer of populations between a
single level and preselected superpositions of energy eigenstates. Viewed in the frequency …

Direct manipulation of charge oscillations in atoms and molecules has emerged as a
remarkable perspective in coherent control of photophysical processes. These oscillations …
