1. 1. Hybrid Microwave Resonator-Nanoscale Conductor Systems

   Master-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Författare :Daniel Larsson Persson; [2023]
   Nyckelord :Circuit Quantum Electrodynamics; Open Quantum Systems; Gaussian States; Two-Mode Two-Photon Jaynes-Cummings Model; Jaynes-Cummings Model; Lyapunov Equation; Phase-Space Description; Duan Criterion; Entanglement; Light-Matter Interaction; Mean Field; Double Quantum Dot; Harmonic Oscillator; Two-Mode Squeezing; Symplectic Form; GKSL Equation; Lindblad Equation; Physics and Astronomy;

   Sammanfattning : Entanglement is a fundamental aspect of quantum computation and quantum information processes. In this work, we analyse the entanglement of two microwave resonators when connected to a semiconductor double quantum dot. LÄS MER

3. 2. Quantum state tomography of attosecond electron wavepackets

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Ron Demjaha; [2022]
   Nyckelord :quantum physics; quantum state tomography; atomic physics; quantum optics; density matrix; entanglement; state mixing; fano resonances; two-photon absorption; Physics and Astronomy;

   Sammanfattning : In this master thesis, a broad theoretical description is done of a novel quantum state tomography protocol called KRAKEN. This protocol is meant for the determination of the density matrix of an electronic state created by absorption of XUV radiation in the vicinity of a Fano resonance. At first, a description of the KRAKEN protocol is provided. LÄS MER

4. 3. Higgs Boson Decay to Two Photons : Probing the Standard Model

   Magister-uppsats, Stockholms universitet/Fysikum

   Författare :Daniel Slominski; [2022]
   Nyckelord :;

   Sammanfattning : The Higgs to Two Photon decay channel is analyzed to one-loop in the Feynman gauge.  Triangle loop processes are evaluated using dimensional regularization due to divergent integrals.  The build up to Higgs physics is given by way of gauge theories in the Standard Model where we can then introduce the Higgs field.

5. 4. Two-Photon Excitation of a GaAs Quantum Dot by Electro-Optically Modulating a Continuous Wave Laser

   Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Julia Schauman; Linnea Bendrot; [2020]
   Nyckelord :;

   Sammanfattning : One of the most important steps towards enabling quantum communication would be to successfully integrate single-photon emitters and quantum memories, enabling the development of quantum repeaters. This is why, as part of a larger project, the objective of this bachelor thesis was to retrieve single-photons suitable for storage inside a Rubidium-based quantum memory. LÄS MER

7. 5. Generation and Characterization of Intense Attosecond Pulses

   Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

   Författare :Marius Plach; [2020]
   Nyckelord :Attosecond physics; high-order harmonic generation; high harmonic generation; HHG; attosecond pulses; molecular dynamics; attosecond pulse generation; harmonic emission time delay; temporal reconstruction of attosecond pulses; strong field processes; Three-step model; RABBIT; Reconstruction of Attosecond Beating By Interference of Two-photon Transition; Terawatt Laser System; Intense XUV Beamline; XUV; LLC; Physics and Astronomy;

   Sammanfattning : Research on ultrafast dynamics in atoms and molecules requires short pulses. In order to resolve processes taking place on a femtosecond timescale sufficiently, these pulses require a duration on the attosecond time scale. LÄS MER
