چکیده
The theory of non-Hermitian systems and the quantum deformations have attracted a great deal attention in past decades. In general, Hamiltonians are constructed by an ad hoc manner. Here, we study ($2+1$) Dirac oscillator show that context $\ensuremath{\kappa}$-deformed Poincar\'e-Hopf algebra its Hamiltonian is but has real eigenvalues. non-Hermiticity stems from algebra. From mapping Bermudez et al., Phys. Rev. A 76, 041801(R) (2007), propose $\ensuremath{\kappa}$-Jaynes-Cummings $\ensuremath{\kappa}$-anti-Jaynes-Cummings models, which describe interaction between two-level system with quantized mode optical cavity context. We find $\ensuremath{\kappa}$ deformation modifies Zitterbewegung frequencies collapses revivals oscillations. particular, total angular momentum $z$ direction not conserved anymore, as direct consequence deformation.

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 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 کاملGrassmann Variables and the Jaynes-cummings Model
1 0.1 Abstract The Jaynes-Cummings model of a two-level atom in a single mode cavity is of fundamental importance both in quantum optics and in quantum physics generally , involving the interaction of two simple quantum systems-one fermionic system (the TLA), the other bosonic (the cavity mode). Depending on the initial conditions a variety of interesting effects occur, ranging from ongoing osc...
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...
