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…
Quantum transport and the Wigner distribution function for Bloch electrons in spatially homogeneous electric and magnetic fields
G. J. Iafrate, V. N. Sokolov, J. B. Krieger
The theory of Bloch electron dynamics for carriers in homogeneous electric and magnetic fields of arbitrary time dependence is developed in the framework of the Liouville equation.…
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…
Electron spin relaxation in semiconducting carbon nanotubes: the role of hyperfine interaction
Y. G. Semenov, K. W. Kim, G. J. Iafrate
A theory of electron spin relaxation in semiconducting carbon nanotubes is developed based on the hyperfine interaction with disordered nuclei spins I=1/2 of C isotopes. It…
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.…
