Diagrammatic treatment of coherent backscattering of intense light by cold atoms with degenerate energy levels [PDF]
We present a generalization of the diagrammatic pump-probe approach to coherent backscattering (CBS) of intense laser light for atoms with degenerate energy levels. We employ this approach for a characterization of the double-scattering signal from optically pumped atoms with the transition ${J}_{g}\ensuremath{\rightarrow}{J}_{e}={J}_{g}+1$ in the ...

Spin–spin relaxation of nuclear quadrupole resonance coherences and the important role of degenerate energy levels [PDF]
We present an extension of a Redfield approach for calculating spin–spin relaxation rates of zero-field nuclear quadrupole resonance (NQR) coherences, which was published in [Kruk et al., PCCP, 201...

FROM BLOCH MODEL TO THE RATE EQUATIONS II: THE CASE OF ALMOST DEGENERATE ENERGY LEVELS [PDF]
Bloch equations give a quantum description of the coupling between atoms and a driving electric force. It is commonly used in optics to describe the interaction of a laser beam with a sample of atoms. In this paper, we address the asymptotics of these equations for a high frequency electric field, in a weak coupling regime.

Riemann-Hilbert Problem with Higher Order Poles for Self-Induced Transparency with Degenerate Energy Levels [PDF]
We have analysed the inverse problem for self-induced transparency with degenerate energy levels (DSIl) via the Riemann-Hilbert methodology with second order poles. The required formulae are deduced in detail and the corresponding soliton solutions are obtained. It is noticed that the profile of the single soliton is not of the usual sech type.

Description of energy levels and decay properties in 158Gd nucleus [PDF]
In this paper, IBM-1 and IBM-2 with a SU(3) limit are used to describe the 158Gd isotope. The calculations of energy levels in the ground state, beta-, and gamma-bands are made up, which account for 15 energy levels.

Photoionization of Electrons in Degenerate Energy Level of Hydrogen Atom Induced by Strong Laser Pulses [PDF]
Photoionization dynamics of bounded electrons in the ground state, the first and second excited states of a hydrogen atom, triggered by ultrashort near-infrared laser pulses, have been investigated in a transition regime (γ∼1) that offers both multiphoton and tunneling features.
