    • Acerca de um mito: o vórtice de Coriolis no ralo da pia 

      Silveira, Fernando Lang da; Axt, Rolando (2000) [Artigo de periódico]
      A explicação usual que afirma ser a força de Coriolis responsável pelos redemoinhos ou vórtices em ralos de pias, tanques ou banheiras é questionada. Descrevem-se os experimentos realizados por Shapiro (1962), com o objetivo ...

    • Nonequilibrium statistical mechanics of two-dimensional vortices 

      Pakter, Renato; Levin, Yan (2018) [Artigo de periódico]
      It has been observed empirically that two-dimensional vortices tend to cluster, forming a giant vortex. To account for this observation, Onsager introduced the concept of negative absolute temperature in equilibrium ...

    • Reply to "Comment on 'Vortex distribution in a confining potential' " 

      Girotto, Matheus; Santos, Alexandre Pereira dos; Pakter, Renato; Levin, Yan (2014) [Artigo de periódico]
      We argue that contrary to recent suggestions, nonextensive statistical mechanics has no relevance for inhomogeneous systems of particles interacting by short-range potentials. We show that these systems are perfectly well ...

    • Spin texture on top of flux avalanches in Nb/Al2O3/Co thin film heterostructures 

      Lopes, Rovan Fernandes; Carmo, Danusa do; Colauto, Fabiano; Ortiz, Wilson Aires; Andrade, Antonio Marcos Helgueira de; Johansen, Tom Henning; Baggio-Saitovitch, E.; Pureur Neto, Paulo (2017) [Artigo de periódico]
      We report on magneto-optical imaging, magnetization, Hall effect, and magneto-resistance experiments in Nb/Al2O3/Co thin film heterostructures. The magneto-transport measurements were performed in samples where electrical ...

    • Vortex glass and vortex liquid in oscillatory media 

      Brito, Carolina; Aronson, Igor S.; Chate, Hugues (2003) [Artigo de periódico]
      We study the disordered, multispiral solutions of two-dimensional oscillatory media for parameter values at which the single-spiral/vortex solution is fully stable. Using the complex Ginzburg-Landau (CGLE) equation, we ...
