A new perspective on the Fano absorption spectrum in terms of complex spectral analysis
Taku Fukuta, Savannah Garmon, Kazuki Kanki +2
A new aspect of understanding a Fano absorption spectrum is presented in terms of the complex spectral analysis. The absorption spectrum of an impurity embedded in semi-infinite su…
Analysis of high-harmonic generation in terms of complex Floquet spectral analysis
Hidemasa Yamane, Satoshi Tanaka, Michelangelo Domina +2
Recent developments on intense laser sources is opening a new field of optical sciences. An intense coherent light beam strongly interacting with the matter causes a coherent motio…
Exact description of coalescing eigenstates in open quantum systems in terms of microscopic Hamiltonian dynamics
Kazuki Kanki, Savannah Garmon, Satoshi Tanaka +1
At the exceptional point where two eigenstates coalesce in open quantum systems, the usual diagonalization scheme breaks down and the Hamiltonian can only be reduced to Jordan bloc…
