  1. 1. Simulation of Quantum Cascade Lasers

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

    Author : Zakaria Mohamed; [2023]
    Keywords : Quantum Cascade Lasers; Simulations; Numerical Methods; Computational Models; Heterostructures; Physics and Astronomy;

    Abstract : This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. READ MORE

  3. 2. Study of luminescent and energy properties of CsPbBr3 and CsPbI3 nanoplatelets

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Taddeo Salique; [2022]
    Keywords : quantum confinement; nanoplatelets; CsPbBr3; CsPbI3; semiconductor; exciton; perovskite nanocrystals;

    Abstract : Halide perovskite semiconductor nanocrystals have been studied a lot recently because they allow a precise control over the entire visible emission spectrum and as a result, the possibility of a variety of light-emitting applications. In this study, cesium lead bromide CsPbBr3 and cesium lead iodide CsPbI3 nanoplatelets of 3, 4 and 5 monolayers (ML) have been synthesized. READ MORE

  4. 3. Rotational Properties of Lee-Huang-Yang Bosonic Condensates from One to Two Dimensions

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

    Author : Hjalmar Holmström; [2022]
    Keywords : BEC; Bose-Einstein condensate; quantum fluid; Quantum mechanics; LHY; LHY-fluid; Lee-Huang-Yang; Rotating BEC; BEC droplet; Physics and Astronomy;

    Abstract : This thesis covers the work of a numerical examination of the rotational properties of a two-component Bose-Einstein condensate (BEC) utilizing the beyond mean-field extended Gross-Pitaevskii equation for a specified set of parameters. These parameters are chosen to cancel the strength of the mean-field interaction, which makes the system predominantly governed by the next order beyond the mean-field Lee-Huang-Yang (LHY) term.

  5. 4. Self-consistent dielectric formalism scheme for the paramagnetic electron gas under warm dense matter conditions

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

    Author : Fotios Kalkavouras; [2022]
    Keywords : Warm Dense Matter WDM ; Quantum One-Component plasmas qOCP ; Vashishta-Singwi VS ; Dielectric Formalism;

    Abstract : The present thesis aims to further a somewhat unexplored area of Warm Dense Matter (WDM) physics through the use of tools developed within the dielectric formalism. WDM is an exotic form of matter with densities close to the solid state and temperatures of several eV. READ MORE

  6. 5. Quantum Simulation of Quantum Effects in Sub-10-nm Transistor Technologies

    University essay from Uppsala universitet/Materialteori

    Author : Anders Winka; [2022]
    Keywords : Transistor Modeling; Quantum Transport; QTBM; Block Cyclic Reduction; Quantum Computing; Quantum Annealer;

    Abstract : In this master thesis, a 2D device simulator run on a hybrid classical-quantum computer was developed. The simulator was developed to treat statistical quantum effects such as quantum tunneling and quantum confinement in nanoscale transistors. READ MORE
