  1. 1. Decay Chains of Fast Alpha Emitters in the Actinide Region

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Tanvir Sayed; [2024]
    Keywords : alpha decay; alpha emissions; fine structure; decay chain; decay scheme; alpha spectrometry; actinide; nucleus; nuclear structure; nuclear states; energy levels; uranium isotopes; U310 experiment; parasitic runs; decay station; TASISpec ; moving window deconvolution; digitisers; alpha-gamma coincidence; 221-Th decay; fine structure of alpha decay to 217-Ra; GSI; Gamow s theory; Geiger-Nuttall; chain search; short half-lives; Physics and Astronomy;

    Abstract : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. READ MORE

  3. 2. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Isa Clementsson; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.

  4. 3. Investigating Tweet Propagation via Dynamical Models and Influencer Analysis

    University essay from Linköpings universitet/Reglerteknik

    Author : Joel Nilsson; [2022]
    Keywords : Social Media Analysis; Dynamical Models; Data Mining;

    Abstract : Social media consume an increasing portion of people’s daily lives and are important platforms in the realms of politics and marketing for reaching out to voters and consumers. Describing and predicting the behaviour of users on social media is thus of interest for companies and politicians, as well as researchers studying information diffusion and human behaviour.

  5. 4. Sharing Quantum Resources Across a Metropolitan Network

    University essay from KTH/Tillämpad fysik

    Author : Martin Carlnäs; [2022]
    Keywords : QKD; Entanglement; SNSPD; Quantum Dot; Exciton; Biexciton; QKD; Kvantsammanflätning; SNSPD; Kvant Prick; Exciton; Biexciton;

    Abstract : Kvantsammanflätning har varit ett populärt ämne bland fysiker i snart 100 år då det tydligt belyser hur annorlunda kvantmekanikens värld är jämfört med den klassiska verklighet vi lever i. Med tiden har kvantsammanflätning blivit mer och mer välförstått och teknologier ämnade att utnyttja det har de senaste årtionden kommit allt närmare till industriell använding. READ MORE

  6. 5. "Fat" Nanobeam-Waveguide Resonator for Suppressing Spectral Diffusion in InGaAs Quantum Dots

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

    Author : Qinda Guo; [2019]
    Keywords : Physics and Astronomy;

    Abstract : The coherent coupling of photons to solid state emitters is one of the building blocks for future quantum technology. However, one of the main sources for non-perfect or even strongly reduced coherence of the photons is charge noise which introduces energy shifts during or in between the photon emission events.
