Normal modes for electromagnetically induced transparency in a lambda system of degenerate energy levels

Quantum Electronics, 2018
This paper presents an analytical study of the formation of normal modes of probe light for electromagnetically induced transparency in a lambda system of quantum transitions between 3P0, and 3P2 levels in the case of an elliptically polarised control ...

Adiabatic Theorem Violation for Degenerate Energy Levels

Physica Scripta, 1999
For the exactly solvable model of a two-mode oscillator with slowly varying frequency of one of the modes it is demonstrated that such a quantum number as the angular momentum of the oscillator is not conserved in the adiabatic limit.

Resonant Degenerate Four-Wave Mixing at the Defect Energy Levels of 2D Organic–Inorganic Hybrid Perovskite Crystals [PDF]

ACS Applied Materials & Interfaces, 2021
Two-dimensional organic-inorganic lead halide perovskites are generating great interest due to their optoelectronic characteristics such as high solar energy conversion efficiency and a tunable direct band gap in the visible regime. However, the presence of defect states within the two-dimensional crystal structure can affect these properties ...

Diagrammatic analysis of adiabatic and time-independent perturbation theory for degenerate energy levels

Chemical Physics Letters, 1978
Time-ordered folded diagrams are used to represent the effective hamiltonian in the adiabatic formalism. Resummation of the diagrams is shown to give a term-by-term correspondence with time-independent perturbation ...
