    • Controle coerente da excitação de modos topológicos em condensados de Bose-Einstein 

      Silva, Leonardo Brito da (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 04/07/2019)
      In this project were carried out a study on dynamics control of one dimensional Bose- Einstein condensates of dilute gases by development and application of techniques on systems that are described by Gross-Pitaevskii ...

    • Coerência espectral da luz espalhada por átomos frios saturados 

      Dias, Pablo Gabriel Santos (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 27/02/2020)
      The spectrum of radiation resonantly scattered by a strongly-driven two-level system consists of three peaks called the Mollow’s triplet. In the case of cold atoms, we can approximate their energy level structure by a ...

    • Incompressible energy spectrum in atomic Bose-Einstein condensates: a weak wave turbulence theory approach 

      Santos Filho, Marcos Alberto Gonçalves dos (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 25/08/2022)
      Bose-Einstein condensates with their superfluidity property provide an interesting parallel to classical fluids. Due to the Kolmogorov spectrum of homogeneous turbulence the statistics of the incompressible velocity field ...

    • O efeito Zeno no controle da evolução adiabática de um sistema quântico a partir de medidas não-seletivas 

      Calvello, Victor dos Santos (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 26/07/2022)
      The objective of the present work is to improve the performance of a Stimulated Raman Adiabatic Passage (STIRAP) in a 3-level system by applying successive non-selective measurements throughout the evolution (exploiting ...

    • Efeito de absorção em espalhamento de elétrons por molécula de formaldeido 

      Ferraz, Jorge Ronan (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 02/10/2011)
      This master's project's main objective is to study the effects of absorption in the elastic scattering of electrons by molecules of formaldehyde (CH2O). We calculated differential cross sections (SCD), integral cross ...

    • Blockade and antiblockade effects with near-ground state neutral atoms 

      Attie, Jorge Antonio Gonçalves (Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 06/09/2022)
      In this work we study the photon blockade and antiblockade effects in a system of neutral atoms with a two-level structure, in the limit where induced dipole-dipole interactions mediated by light are relevant. Such system ...
