  2. 6. Diffusion studies in gels using holographic laser interferometry

    Author : Charlotte Mattisson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical potential; ionic strenght; pH; cubic phase; partition coefficient; holographic laser interferometry; holography; pullulan; lysozyme; BSA; macromolecules; diffusion; gel; Poisson-Boltzmann; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : This thesis is an investigation of the potential of holographic laser interferometry for the study of diffusion of both small solutes and macromolecules. An investigation on the importance of errors due to light deflection in refarctive index gradients showed that the magnitude of the refractive index gradients were negligible for the system investigated.

  4. 7. Holographic descriptions of collective modes in strongly correlated media

    Author : Marcus Tornsö; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasmonics; strongly correlated media; holography; gauge gravity duality; graphene; strong coupling; quasinormal modes;

    Abstract : Solving the puzzle of high temperature superconductivity may be one of the most desired scientific breakthroughs of our time, as access to room temperature superconductivity could revolutionize society as we know it. In this thesis, we strive to increase the theoretical understanding of such matter, by studying the phase above, in temperature, the superconducting phase - the "strange metal". READ MORE

  5. 8. Plasma Oscillations in Holographic Quantum Matter

    Author : Marcus Tornsö; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; holography; quasinormal modes; gauge gravity duality; graphene; strong coupling; plasmonics; strongly correlated media;

    Abstract : In this thesis we explore strongly correlated matter in the framework of holographic duality. Specifically, we examine the quasinormal modes of such systems, and we extend the current framework to efficiently and naturally cover plasmons and other collective modes that may be found within strongly correlated matter.

  6. 9. Multiplexed Digital Holography incorporating Speckle Correlation

    Author : Davood Khodadad; Pascal Picart; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik; Technology byts ev till Engineering ;

    Abstract : In manufacturing industry there is a high demand for on line quality control to minimize the risk of incorrectly produced objects. Conventional contact measurement methods are usually slow and invasive, meaning that they cannot be used for soft materials and for complex shapes without influencing the controlled parts. READ MORE

  7. 10. 3D localization in digital holography from scattered light from micrometer-sized particles

    Author : Johan Öhman; Mikael Sjödahl; Per Bergström; Erik Olsson; Torbjörn Löfqvist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital Holography; Polarization; Particle Scattering; Metrology; Experimentell mekanik; Experimental Mechanics;

    Abstract : When a particle is illuminated by a beam of light it will scatter and redistribute the light in all directions. How it scatters depends on the size, shape and refractive index of the particle. Additionally, it depends on the wavelength and polarization of the illuminating beam. READ MORE
