Quantum Entanglement in Double Quantum Systems and Jaynes-Cummings Model
In the paper, we proposed a new approach to producing the qubits in electron transport in low-dimensional structures such as double quantum wells or double quantum wires (DQW). The qubit could arise as a result of quantum entanglement of two specific states of electrons in DQW structure. These two specific states are the symmetric and antisymmetric (with respect to inversion symmetry) states ar...
متن کاملSemiclassical Dynamics of the Jaynes-Cummings Model
The semiclassical approximation of coherent state path integrals is employed to study the dynamics of the Jaynes-Cummings model. Decomposing the Hilbert space into subspaces of given excitation quanta above the ground state, the semiclassical propagator is shown to describe the exact quantum dynamics of the model. We also present a semiclassical approximation that does not exploit the special p...
متن کاملJaynes-cummings Model with Degenerate Atomic Levels
The Jaynes-Cummings model describing the interaction of a single linearlypolarized mode of the quantized electromagnetic field with an isolated two-level atom is generalized to the case of atomic levels degenerate in the projections of the angular momenta on the quantization axis, which is a usual case in the experiments. This generalization, like the original model, obtains the explicit soluti...
متن کاملOptical Spectra of the Jaynes-Cummings Ladder
We explore how the Jaynes-Cummings ladder transpires in the emitted spectra of a twolevel system in strong coupling with a single mode of light. We focus on the case of very strong coupling, that would be achieved with systems of exceedingly good quality (very long lifetimes for both the emitter and the cavity). We consider the incoherent regime of excitation, that is realized with semiconducto...
متن کاملQuantum statistical properties of the Jaynes-Cummings model in the presence of a homogeneous gravitational field
The temporal evolution of quantum statistical properties of an interacting atom-field system in the presence of a homogeneous gravitational field is investigated within the framework of the Jaynes-Cummings model. Taking into account both the atomic motion and gravitational field a full quantum treatment of the internal and external dynamics of the atom is presented based on an alternative su(2)...
