Shuyun Zhou (Lawrence Berkeley National Lab, Berkeley, CA, USA)06/04/2011, 09:10TalkCharge, orbital and spin orderings play an important role in transition metal oxides. In colossal magnetoresistance (CMR) manganites, the melting of the CE-type charge, orbital and spin ordering is believed to be directly relevant to the colossal change in resistance which can be induced by various external perturbations. Here I will present our recent results on the spin and orbital ordering...Go to contribution page

2. Theory of photoinduced electron-phonon-coupled dynamics in two-dimensional charge-ordered systemsKenji Yonemitsu (Institute for Molecular Science)06/04/2011, 09:30TalkPhotoexcitations cause phase transitions from different types of insulators to metals in organic compounds. Their ultrafast dynamics are theoretically studied on the basis of electron-phonon-coupled wave functions in extended Holstein-Peierls-Hubbard models on anisotropic triangular lattices. We focus on 2D 1/4-filled-band charge-ordered insulators, \theta-(BEDT-TTF)2RbZn(SCN)4 and...Go to contribution page
