Quantum state tomography of attosecond electron wavepackets

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. Then, the theory of Fano resonances is discussed. After that, the physics of two-photon transitions is presented. Finally, possible expansions of KRAKEN using chirped or broadband IR probe pulses, are examined.
