Exact Ionization Amplitudes for a Delta-Function Well in an Arbitrary-Strength DC Electric Field
Ilki Kim, Gerald J. Iafrate
We investigate finite-time field-induced ionization from a one-dimensional attractive delta-function well in a uniform dc electric field of arbitrary strength. Our aim is to determ…

Entanglement in the interaction between two quantum oscillator systems
ILki Kim, Gerald J. Iafrate
The fundamental quantum dynamics of two interacting oscillator systems are studied in two different scenarios. In one case, both oscillators are assumed to be linear, whereas in th…

Comment on the quantum nature of angular momentum using a coupled-boson representation
ILki Kim, Gerald J. Iafrate
A simple approach for understanding the quantum nature of angular momentum and its reduction to the classical limit is presented based on Schwinger's coupled-boson representation.…
