1. 1. Fano Resonances in Time-Dependent Wells

   L3-uppsats, Uppsala universitet/Materialteori

   Författare :Anton Gregefalk; [2023]
   Nyckelord :Fano resonance; Floquet scattering; Pumped shot-noise; Linear band tilt; Quadratic band touching; Time periodic Hamiltonian;

   Sammanfattning : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. LÄS MER

3. 2. Adiabatic Shortcut to Geometric Quantum Computation in Noiseless Subsystems

   Kandidat-uppsats, Uppsala universitet/Materialteori

   Författare :Anton Gregefalk; [2021]
   Nyckelord :Quantum computer; Spin echo; Adiabatic shortcut; Berry s phase; Noiseless subsystems; Kvantdator; spinn eko; adiabatisk genväg; Berrys fas; Brusfria delsystem;

   Sammanfattning : Quantum computers can theoretically perform certain tasks which classical computers at realistic times could not. Operating a quantum computer requires precise control over the system, for instance achieved by adiabatic evolution, and isolation from the environment to retain coherence. LÄS MER
