  1. 6. Real-time stability and dynamics of vortices in quasi-two-dimensional self-bound two-component Bose-Einstein condensate

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Philipp Stürmer; [2019]
    Keywords : Bose-Einstein condensate; bosons; self-bound; cold atom gases; vortex; Physics and Astronomy;

    Abstract : This thesis presents a numerical study of the beyond mean field extended Gross-Pitaevskii equation for a two-component self-bound Bose-Einstein condensate, supplemented by analytical work. We extend the quasi-two-dimensional system's mean field particle-particle contact interaction by quantum fluctuations (LHY-correction). READ MORE

  3. 7. Correlated Structure-Property Investigation of Ultrathin InAs Nanowires

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Linnea Suomenniemi; [2019]
    Keywords : Nanowires; InAs; epitaxy; MBE; Photo luminescence; Physics and Astronomy;

    Abstract : III-V semiconductors are a profound part of the optoelectronics industry and new developments in alloy compositions and architectures are constantly emerging. Lowdimensional semiconductors, such as nanowires (NWs) have shown to have improved characteristics in certain areas such as enhanced light absorption and can furthermore be integrated on Silicon (Si) plattforms and are thus predicted to be a key component in future nanoelectronic and nanophotonic applications and devices.

  4. 8. Ultra-Thin Ag Films on the Sn/Si(111)-√3×√3 Surface Studied by STM

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Rasmus Lavén; [2018]
    Keywords : Silver; Silicon; Tin; Metal-semiconductor interfaces; Thin metal films; Scanning tunneling microscopy; Quantum size effects;

    Abstract : The growth of atomically flat silver films on Si(111) usually requires a two-step growth, including deposition at low temperature (≈100 K) followed by slowly annealing to room temperature. In addition, flat silver films are usually only obtained on Si(111) for film thicknesses larger than the critical thickness of 6 monolayer. READ MORE

  5. 9. Performance evaluation of quantum Fourier transform on a modern quantum device

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sven Anderzén Rodenkirchen; Marcus Granström; [2018]
    Keywords : ;

    Abstract : Quantum computing has in the last decades gone from a purely theoretical concept to being implemented on actual devices in the real world. However, one of the major challenges of quantum computing still remains; its sensitivity to noise. READ MORE

  6. 10. Understanding Sn-seeded InSb nanowire growth

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Hengfang Zhang; [2017]
    Keywords : Science General;

    Abstract : III-Sb semiconductor nanowires have drawn a lot of attention because of their many promising applications, such as thermoelectric generation, low power high efficient electronics and quantum transport. Gold as a catalyst seed particle has been dominating for many years assisting nanowires growth. READ MORE
