Characteristic influence of exceptional points in quantum dynamics
Savannah Garmon, Takafumi Sawada, Kenichi Noba +1
We review some recent work on the occurrence of coalescing eigenstates at exceptional points in non-Hermitian systems and their influence on physical quantities. We particularly fo…
Anomalous-order exceptional point and non-Markovian Purcell effect at threshold in one-dimensional continuum systems
Savannah Garmon, Gonzalo Ordonez, Naomichi Hatano
For a system consisting of a quantum emitter coupled near threshold (band edge) to a one-dimensional continuum with a van Hove singularity in the density of states, we demonstrate…
Coherent single-spin electron resonance spectroscopy manifested at an exceptional-point singularity in a doped polyacetylene
Yujin Dunham, Kazuki Kanki, Savannah Garmon +2
Spin-dependent charge transfer decay in an alkali atom doped polyacetylene is studied in terms of the complex spectral analysis, revealing the single-spin Zeeman splitting influenc…
Non-Markovian dynamics revealed at the bound state in continuum
Savannah Garmon, Kenichi Noba, Gonzalo Ordonez +1
We propose a methodical approach to controlling and enhancing deviations from exponential decay in quantum and optical systems by exploiting recent progress surrounding another sub…
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…
