 * Issues in Strong Field /Attophysics**

-- core rearrangement -- hole dynamics (core, valence) -- analyzing time-dependent processes in shake-off, such as
 * understanding ionization in polyatomic molecules
 * understanding and imaging
 * -- bound multi-electron dynamics
 * pump-probe imaging of core-hole dynamics
 * role of nuclear motion
 * Issues in Control related to strong fields and attosecond physics**

-How does initial attosecond dynamics affects fs evolution, such as non-adiabatic transitions at the conical intersections? While motion through the conical intersection is fsec, initial preparation of the electronic wavepacket is important. -How can electronic motion (e.g. chaotic electron dynamics) affect nuclear motion on a much longer time-scale? -How much control over the attosecond pulse shape can one have? How can we shape asec pulses: amplitudes, phases, polarizations? - Controlling free electrons is easy. What about control of electron motion in systems with nontrivial dispersion, such as conduction bands + controlling e- motion in dispersive media - Electron pump-dump: Control of electron transfer or hole transfer in polyatomic molecules. - Control of currents, including ring currents - Control of spin dynamics for electrons and holes, control of spin-orbit coupling by controlling nuclear orbitals - Control of strong-field ionization, including electron tunnelling - Can a.s. pulses be used to control mass spectra after double ionization? - Control of harpooning reaction


 * Notes and questions**

Can one use light to trigger formation of Cooper pairs? Can one use light to trigger/reverse phase transitions? Creating and controlling excitations in solids – BEC of excitons (correlated electron-hole pairs) Can laser demagnetization be reversed to give magnetization? DIET (desorption induced electron transfer) --- surface electron control

Polarized light Two-color control (time delay, polarization) Angular distribution Controlling tunneling electron H+ and H2+ (H3++) control of final products using absolute phase Control of time for electron wavepacket by the photon wavepacket Ion impact as a.s. control Artificial atoms --- add electrons one by one
