  1. 1. Nonlinear Beam Physics

    University dissertation from Lund University , Department of physics

    Author : Benjamin Folsom; Lund University.; Lunds universitet.; [2019-03-30]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nonlinear dynamics; Beam dynamics; Accelerator Physics; space charge; Accelerator magnets; simulations multi-particle dynamics;

    Abstract : A condensed treatment of conventional beam physics (both linear and nonlinear) is given for the non-expert; this constitutes a minimum knowhow for constructing simulations of rudimentary beamlines. The criteria for an ideal nonlinear charged-particle simulation algorithm are then presented, leading to the derivation of a symplectic, explicit, Lorentz-covariant integrator. READ MORE

  3. 3. Diffusion-Induced Nonlinear Dynamics in Carbon Nanomechanical Resonators

    University dissertation from Stockholm : KTH

    Author : Christin Edblom; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mass sensing; graphene; stochastic differential equations; diffusion; carbon nanotubes; resonators; nanoelectromechanical systems; equations of motion; nonlinear dynamics; dissipation; Fokker-Planck equation; noise; nonequilibrium dynamics;

    Abstract : The emergence of nanoelectromechanical systems has enabled the development of sensors capable of detecting mass, charge, force, position, and spin with an unprecedented precision. In particular, the low mass, high resonant frequency, and high quality factor of carbon nanomechanical resonators make them ideal for the creation of a high sensitivity mass sensor. READ MORE
