  1. 1. Superradiant axion clouds and their interaction with astrophysical plasma

    University essay from KTH/Fysik

    Author : Erik Engstedt; [2021]
    Keywords : axions; superradiance; black holes; black hole accretion; astrophysical plasma; axioner; strålningsförstärkning; svarta hål; svart hålansamling; astrofysikalisk plasma;

    Abstract : Axions are one of the best-motivated particles beyond the standard model of particle physics and a promising candidate for dark matter. Through the superradiant instability, axions can extract a significant amount of rotational energy from spinning black holes resulting in dense axion clouds. READ MORE

  3. 2. Study of Dicke’s Model for Superradiance at Short Wavelengths from Core-excited Atoms

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

    Author : Xiaolin Bian; [2019]
    Keywords : Physics and Astronomy;

    Abstract : The main objective of this study is to contribute toward a comprehensive understanding of the superradiance problem in a short wavelength regime ($100$ to $100$ eV). In this regime, superradiance is influenced by Auger effect which would compete with normal superradiance process, and we want to study if it is possible to generate ultra-short pulses on the femtosecond or attosecond timescale using Dicke superradiance.
