  2. 1. Generation and Transmission of Optical Solitons at Ultrahigh Bit Rates

    Author : Bamdad Bakhshi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear optics; chirp-free optical pulses; lowpass filtering; polarization-maintaining fibers; optical communication; optical solitons; Erbium fiber ring laser; dispersion-management; active mode-locking; soliton interactions; erbium-doped fiber amplifier; Gaussian pulses;

    Abstract : This thesis deals with the generation and transmission of optical solitons in ultrahigh-speed fiber-optic communication systems. For optical soliton pulses the fiber dispersion and nonlinearity can under certain circumstances cancel each other, thus allowing the solitons to remain undistorted over long distances. READ MORE

  4. 2. Solitons, vortices and shell structure in ultracold atomic quantum systems

    Author : Gunnar Eriksson; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; few-body physics; finite-size effects; solitary waves; quantized vortices; quantum hysteresis; shell structure; dipolar interactions; Fysicumarkivet A:2020:Eriksson;

    Abstract : This dissertation deals with finite-size effects in a few different quantum many-body phenomena in ultracold atomic systems. The finite-sized systems were simulated numerically using both mean-field methods and methods beyond mean-field, e.g. quadratic configuration interaction and exact diagonalization. READ MORE

  5. 3. Novel Phenomena in Superconductors and Superfluids: Boundary States, Spiral Magnetic Fields, and Solitons
