    • Evidence of homoclinic chaos in the plasma of a glow discharge 

      Braun, Thomas; Lisboa, Jorge Amoretti; Gallas, Jason Alfredo Carlson (1992) [Artículo de periódico]
      Homoclinic chaos is shown to occur in the electric current measured on an electrical discharge in argon. We report a clear sequence of four hesitations followed by a reverse period doubling. The experimental signals are ...

    • A graphite thermal evaporation source for aluminum 

      Folz, Yuri Alberto; Hickmann, Janir Sebastião; Braun, Luci Fortunata Motter; Francke Sandoval, Ricardo Eugenio (1990) [Artículo de periódico]

    • Influence of wave dispersion on the self-consistent dynamics of cyclotron-laser-type systems 

      Pakter, Renato; Schneider, Ruth de Souza; Rizzato, Felipe Barbedo (1993) [Artículo de periódico]
      In this work, we make use of a Hamiltonian formalism to analyze the wave-particle dynamical interaction that takes place in cyclotronic systems. It is shown that the usual model of test particles moving in externally given ...

    • Observation of the transparency of a resonant medium to zero-degree optical pulses 

      Grieneisen, Hans Peter Henrik; Goldhar, J.; Kurnit, N.A.; Javan, A.; Schlossberg, H.R. (1972) [Artículo de periódico]
      Experiments are described in which low-intensity laser pulses of zero area [f:'m8(z, t) dt=O) are propagated through a degenerate resonantly absorbing medium with greatly reduced absorption. These pulses are constructed ...
