  1. 1. Estimation of Parabolic Microwave Antenna Movements Using Sensor Fusion

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Nikhil Challa; [2023]
    Keywords : Technology and Engineering;

    Abstract : Wireless communication has seamlessly integrated itself into our daily lives, with Ericsson pioneering the development of comprehensive mobile ecosystems. As the demand for data traffic continues to surge, the enhancement of both cellular radio systems and backhaul infrastructure remains paramount. READ MORE

  3. 2. Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs

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

    Author : Emil Adam Jonatan Östberg; [2023]
    Keywords : skyrmion; skyrmions; NEGF; freen s function; quantum transport; non-equlibrium; topology; topological charge; skyrmionics; current induced; open system; Physics and Astronomy;

    Abstract : A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. READ MORE

  4. 3. Towards a Cooper pair splitter in InAs nanowires with crystal-phase defined quantum dots

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Lunds Tekniska Högskola

    Author : Louise Olausson; [2022]
    Keywords : Cooper pair splitter; quantum dot; nanowire; superconductivity; InAs; crystal-phase; Physics and Astronomy;

    Abstract : Cooper pair splitting (CPS) is a process in which the two spin-entangled electrons of a Cooper pair in a superconductor are split into two spatially separated electrons. If the separated electrons are still entangled, CPS can be studied to increase the knowledge of non-locality in quantum systems. READ MORE

  5. 4. Electronic states in semiconductor double quantum dots and quantum rings - Theory and tight-binding modeling

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

    Author : Calle Stenberg; [2021]
    Keywords : double quantum dots quantum rings tight-binding aharonov-bohm g-factor enhancement InAs; Physics and Astronomy;

    Abstract : In recent experiments on semiconductor nanowires and quantum dots, enhanced g-factors up to several times the bulk value have been measured [1] [2]. The enhancement is attributed to orbital contributions g∗orb to the effective g-factor g∗ = g∗spin+g∗orb from the coupling of the high angular momentum ring-like states to the magnetic field.

  6. 5. Developing a Resonance Correction Scheme in the LHC

    University essay from Uppsala universitet/FREIA

    Author : Elias Waagaard; [2021]
    Keywords : ;

    Abstract : Non-linear errors in the magnetic field of the Large Hadron Collider (LHC) at CERN often lead to undesirable resonances and instabilities in the particle motion, which can negatively affect the operations of the accelerator. This project focuses on developing a new correction scheme with a response matrix approach to optimize the values of the skew sextupolar correctors of the LHC at injection, in order to mitigate the impact of resonance driving terms (RDTs).
