DESCRIPTION:Prof. Fabrizio Carbone\, LUMES\, Institute of Condensed Matter
  Physics\, EPFL\nIn this seminar\, we review few results obtained by means
  of ultrafast optical and electron-based techniques in condensed matter ph
 ysics.\nWe will introduce the general concepts behind ultrafast experiment
 s and show examples involving high-temperature superconductors\, magnetic 
 materials and nano structures. \nStrong on-site Coulomb repulsions govern
  the physics of several complex oxydes. In particular\, multiferroic mater
 ials\, high-temperature superconductors\, charge and orbitally ordered ins
 ulators among others\, belong to this family of compounds. Spectroscopical
 ly\, valuable information comes from the quantification of the coupling pa
 rameters between low-energy excitations\, such as phonons or spin-waves\, 
 and the high energy charge-transfer or Mott-Hubbard electronic states. The
  results of our recent studies on high-temperature superconductors and ins
 ulating magnetic oxides will be discussed in which information on such a c
 oupling is  obtained via the Impulsive Stimulated Raman Scattering mechan
 ism. The resonance between the many-body ground state responsible for the 
 electronic properties of these materials\, and the Charge-Transfer or Mott
  gap will be discussed.\nBio: Master degree: University of Pavia "optoelec
