Weak-coupling bound states in semi-infinite topological waveguide QED
Savannah Garmon, Gonzalo Ordonez, Kenichi Noba
A striking feature of cavity quantum electrodynamics is the existence of atom-photon bound states, which typically form when the coupling between the atom and its environment are s…
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…
Reservoir-assisted symmetry breaking and coalesced zero-energy modes in an open PT-symmetric Su-Schrieffer-Heeger model
Savannah Garmon, Kenichi Noba
We study a model consisting of a central -symmetric trimer with non-Hermitian strength parameter coupled to two semi-infinite Su-Schrieffer-Heeger (SSH) leads. We…
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…
