Quantum control of bound and continuum state dynamics

Quantum coherent control of the photoelectron angular distribution in bichromatic-field ionization of atomic neon

“…The phase control of photoprocesses has been the subject of numerous studies and reviews [1][2][3][4][5][6][7]. Quantum coherent-control approaches have been developed for such promising applications as control of chemical reactions or biological changing [8], ultrafast and nonlinear optics [9,10], and 4D ultrafast electron microscopy [11,12], to name just a few.…”

Relaxation of excited molecules in a medium with memory at short and long times

“…Many works were concerned with experi mental and theoretical femtochemical studies, in par ticular, with coherent dynamics control of various reactions (e.g., see reviews [1][2][3][4][5][6]). Modern interests in femtochemistry almost fully shifted toward studies of processes in condensed media (in the first place, in liquids) and coherent process control [3][4][5][6][7]. A description of femtochemical processes should be per formed taking into account a new (compared with the gas phase) qualitative effect.…”

“…This is the type of Redfield equations. Interestingly, Redfield equations are used in the majority of works concerned with femtochemical pro cesses in condensed media [5,6].…”

Adiabatic Concentration and Coherent Control in Nanoplasmonic Waveguides

“…The coherent control of the quantum state of atom and molecules is based on the directed interference of the different quantum pathways of the optical excitation, [16][17][18][19][20][21][22][23][24][25] which is carried out by properly defining the phases of the corresponding excitation waves. This coherent control can also be imposed by an appropriate phase modulation of the excitation ultrashort (femtosecond) pulse.…”

“…One of the most rapidly developing directions in ultrafast optics is quantum control, in which coherent superpositions of quantum states are created by excitation radiation to control the quantum dynamics and outcomes. 22,25,71,72 Of special interest are coherently controlled ultrafast phenomena on the nanoscale where the phase of the excitation waveform along with its polarization provides a functional degree of freedom to control the nanoscale distribution of energy. 15,[31][32][33][34]36,73 Spatiotemporal pulse shaping permits one to generate dynamically predefined waveforms modulated both in frequency and in space to focus ultrafast pulses in the required microscopic spatial and femtosecond temporal domains.…”
