Adiabatic excitation of a confined particle in one dimension with a variable infinitely sharp wall
Sho Kasumie, Manabu Miyamoto, Atushi Tanaka
It is shown that adiabatic cycles excite a quantum particle, which is confined in a one-dimensional region and is initially in an eigenstate. During the cycle, an infinitely sharp…
Cheon's anholonomies in Floquet operators
Manabu Miyamoto, Atushi Tanaka
Anholonomies in the parametric dependences of the eigenvalues and the eigenvectors of Floquet operators that describe unit time evolutions of periodically driven systems, e.g., kic…
Quasienergy anholonomy and its application to adiabatic quantum state manipulation
Atushi Tanaka, Manabu Miyamoto
The parametric dependence of a quantum map under the influence of a rank-1 perturbation is investigated. While the Floquet operator of the map and its spectrum have a common period…
Zero energy resonance and the logarithmically slow decay of unstable multilevel systems
Manabu Miyamoto
The long time behavior of the reduced time evolution operator for unstable multilevel systems is studied based on the N-level Friedrichs model in the presence of a zero energy reso…
Bound-state eigenenergy outside and inside the continuum for unstable multilevel systems
Manabu Miyamoto
The eigenvalue problem for the dressed bound-state of unstable multilevel systems is examined both outside and inside the continuum, based on the N-level Friedrichs model which des…
Initial state maximizing the nonexponentially decaying survival probability for unstable multilevel systems
Manabu Miyamoto
The long-time behavior of the survival probability for unstable multilevel systems that follows the power-decay law is studied based on the N-level Friedrichs model, and is shown t…
