    A Cristalografia Estrutural no Brasil

    Lembraremos inicialmente que o primeiro cientista no Brasil foi José Bonifácio de Andrada e Silva, mineralogista de reputação internacional mais conhecido por sua participação na independência do Brasil. Será discutida a importância da Cristalografia Estrutural, tanto antes como após a descoberta da difração de raios X. Será analisada a evolução dos seus equipamentos e metodologias e sua implantação no Brasil através da ação de vários pesquisadores. Finalmente será apresentada uma breve visão do seu estágio atual no Brasil e as perspectivas para o futuro a nível nacional e internacional.

    Data: 28/08, 13:30h

    Local: Auditório do Espaço Físico Integrado (EFI).

    Em julho deste ano a Profa. Yvonne foi homenageada pela International Union of Pure and Applied Chemistry (IUPAC) com o prêmio IUPAC-2017 Distinguished Women in Chemistry or Chemical Engineering Awards. Abaixo uma reportagem publicada na revista Pesquisa FAPESP.

    THE PHYSICS GRADUATE PROGRAM invites everyone to the seminar: 

      Dirac Electrons in Two Dimensional Crystals 

    Sergio E. Ulloa

    Department of Physics and Astronomy and Nanoscale and Quantum Phenomena Institute

    Ohio University

    Abstract:

    Graphene, a monoatomic layer of carbon, is perhaps the simplest and most easily available material where electrons behave as massless Dirac particles.  Apart from its many promising technological applications, the study of graphene (and other layered materials) has opened a number of interesting theoretical questions:  the microscopic crystalline structure requires an additional degree of freedom (the pseudo spin) that gives rise to effects such as the Klein paradox or Veselago electron lenses.

    This relativistic dynamics is further emphasized by the presence of an interesting relativistic effect: the spin-orbit interaction (SOI), which is present in materials that lack inversion symmetry in the lattice structure or arises from external or interfacial fields that break spatial symmetries. Although SOI is weak in natural graphene, it can be enhanced by local hybridizations with impurities by manipulation of substrates or applied gates. Moreover, the effective exchange interactions between magnetic impurities in this and related 2D materials exhibit interesting behavior.

    In this talk, I will present our studies of electronic transport and Kondo screening in graphene, as well as the role of intrinsic SOI in transition metal dichalcogenides in mediating RKKY interactions.

  • Seminar with postdoctorate Massimo Ostilli – August 11, 2017 – 10h10min

    Publicado em 07/08/2017 às 11:29 AM

    THE PHYSICS GRADUATE PROGRAM invites everyone to the seminar: 

    Thermalization in black-body radiation and application to the Lipkin-Meshkov-Glick model. 

    Massimo Ostilli

    Pós-doutorando/UFSC

     Abstract:

    In a recent work, we have derived simple Lindblad-based equations for the thermalization of systems in contact with a thermal reservoir.  Here, we apply these equations to the Lipkin-Meshkov-Glick model (LMG) in contact with a blackbody radiation and analyze the dipole matrix elements involved in the thermalization process.  We find that the thermalization can be complete only if the density is sufficiently high, while, in the limit of low density, the system thermalizes partially, namely, within the Hilbert subspaces where the total spin has a fixed value. In this regime, and in the isotropic case, we evaluate the characteristic thermalization time analytically, and show that it diverges with the system size in correspondence of the critical points and inside the ferromagnetic region.  Quite interestingly, at zero temperature the thermalization time diverges only quadratically with the system size, whereas quantum adiabatic algorithms, aimed at finding the ground state of same system, imply a cubic divergence of the required adiabatic time.
