DESCRIPTION:Multidimensional spectroscopy uses sequences of optical pulses 
 to study dynamical processes in complex molecules through correlation plot
 s involving several time delay periods. Extensions of these techniques to 
 the x-ray regime will be discussed. Ultrafast nonlinear x-ray spectroscopy
  is made possible by newly developed free electron laser and high harmonic
  generation sources. The attosecond duration of X-ray pulses and the atomi
 c selectivity of core X-ray excitations offer a uniquely high spatial and 
 temporal resolution. Stimulated Raman detection of an X-ray probe may be u
 sed to monitor the phase and dynamics of nonequilibrium valence electronic
  state wavepackets created by e.g. photoexcitation\, photoionization and A
 uger processes. Novel ultrafast X ray probes for strongly coupled electron
 -nuclear dynamics \, techniques based on a coherent stimulated Raman proce
 ss that employs a composite femtosecond/attosecond X-ray pulse to directly
  detect the electronic coherences (rather than populations) \, and new ima
 ging techniques based on x-ray diffraction from electronic coherence will 
 be presented. Nonlinear optical signals induced by quantized light fields 
 and entangled photon pairs are presented. Conventional nonlinear spectrosc
 opy uses classical light to detect matter properties through the variation
  of its response with frequencies or time delays. Quantum light opens up n
 ew avenues for spectroscopy by utilizing parameters of the quantum state o
 f light as novel control knobs and through the variation of photon statist
 ics by coupling to matter. Entangled-photon pairs are not subjected to the
  classical Fourier limitations on the joint temporal and spectral resoluti
 on. Strong coupling of molecules to the vacuum field of micro cavities can
  modify the potential energy surfaces thereby manipulating the photophysic
 al and photochemical reaction pathways. Crossings of electronic potential 
 surfaces in nuclear configuration space\, known as conical intersections\,
  determine the rates and outcomes of virtually all photochemical molecular
  processes. Strong coupling of molecules to the quantum vacuum field of mi
 cro cavities that can be used to manipulate their photophysical and photoc
 hemical reaction pathways and polariton relaxation in photosynthetic anten
 nae are demonstrated.\nSpeaker: Shaul Mukamel
