  • Second SCL seminar by Nikola Buric
    the qualitative propagation of entanglement evolution and the QI and QC of the quantum system which depend on the properties of the initial state He also discussed how geometric properties of the quantum state diffusion metric e g the curvature are indicators of asymptotically stable states and in classical mechanics sufficient symmetry is almost synonimous with complete integrability and the lack of symmetry implies classical chaoticity In the quantum case

  • SCL seminar by Ross McKenzie
    electronic properties of elemental metals However there is considerable debate about the stability and quantum numbers and even the existence of quasiparticles in a wide range of strongly correlated electron materials 1 Prominent examples include transition metal oxides high Tc cuprate superconductors and heavy fermion compounds The frequency dependent optical conductivity has proven to be a powerful experimental probe in addressing these issues I will describe a recent combined theoretical and experimental study of the low energy electrodynamics of charge carriers close to the Mott metal insulator transition in a quasi two dimensional organic charge transfer salt 2 The frequency dependence of the conductivity deviates significantly from the Drude model behavior characteristic of elemental metals There is a strong redistribution of spectral weight as the Mott transition is approached and with temperature The quasiparticles only exist at relatively low energies and their effective mass increases considerably near the insulating phase A dynamical mean field theory treatment of the relevant Hubbard model gives a good quantitative description of the experimental data 2 1 R H McKenzie Nature Physics 3 756 2007 2 J Merino M Dumm N Drichko M Dressel and R H McKenzie Phys Rev Lett 100 086404 1 4

  • SCL seminar by Milan Zezelj
    recent work together with V Milovanovic and J Radovanovic In particular it was discussed that influence of interface roughness scattering is not negligible and it gives a very important contribution in calculating optical gain of quantum cascade laser Influence LO phonon and interface roughness scattering on quantum cascade laser in strong magnetic field News 12 February 2016 SCL Seminar by Jelena Smiljanic 12 January 2016 In memoriam Nikola Buric 28

  • SCL seminar by Alexandru Nicolin
    Nicolin et al Phys Rev A 76 063609 and Physica A 389 4663 Engels et al have showed experimentally that an elongated high density cigar shaped condensate subject to periodic modulation of its transverse confinement excites small amplitude longitudinal oscillations through a parametric resonance i e Faraday waves In my talk I will give a complete analysis of the instability using an effectively one dimensional model that captures the main

    wave scattering length via Feshbach resonance Combining an analytical perturbative approach with numerical simulations we analyze the resulting nonlinear dynamics of the system on the mean field Gross Pitaevskii level Our detailed results show the presence of higher harmonics and mode coupling Most importantly we also find significant shifts of the collective modes frequencies in the resonance region which are due to the nonlinearity of the system dynamics Finally we
