      Quase-Integrabilidade 

    Prof. Dr. Pawel Klimas – FSC/UFSC

    Abstract:

    Os modelos integráveis em física possuem propriedades matemáticas muito especiais o que faz com que os mesmos sejam muito raros. Uma destas propriedades manifesta-se na existência de soluções chamadas sólitons. Os sólitons propagam-se sem dispersão, e quando colidem não geram radiação. Esta propriedade é bem entendida dentro de formalismo matemático que descreve teorias integráveis. Os sólitons aparecem em grande abundância em muitas áreas da física: teoria de campos, óptica não-linear (fibras ópticas), cadeias de spin e até em cadeias de DNA. Os sólitons observados na natureza comportam-se de maneira muito parecida aos sólitons ideais em modelos integráveis. Isto leva à hipótese de que a natureza pode ser descrita por deformações de modelos integráveis, que apesar de perderem a integrabilidade, ainda preservam as características principais dos modelos integráveis. Este fenômeno foi chamado de quase-integrabilidade e foi testado em alguns modelos, como por exemplo, o modelo modificado de Schrodinger não-linear. Neste seminário será apresentada uma visão geral deste fenômeno e a sua ilustração, tomando-se como exemplo o modelo de Toda afim com dois campos.

      Memristors: a primer and perspectives 

    Prof. Dr. Gilberto Medeiros

    UFMG

     Abstract:

    Memristors are one class of devices that cannot be described or emulated by association of resistors, capacitors and inductors. A pinched hysteresis is usually the fingerprint of memristive behaviour [1,2]. Beyond simple modelling presented in the early 70s [1,2], significant experimental progress has been achieved, to the point where now there are several companies and research teams working with these devices in a number of applications ranging from neuromorphic computing [3,4] to non-volatile memories [5]. Here I will discuss the anatomy of conductive channels in memristors, by means of structural and chemical characterization afterproper identification through pressure modulated conductance experiments [6]. Subsequently, the upper limits of switching speeds of these devices will be discussed [7], as well as our modelling results [8]. Finally, complementing the modelling picture I will conclude showing our latest results on noise characteristics of these intriguing devices [9].
