TLDR
In this paper, it was shown that multiphoton coherent states can be expressed as linear quantum superpositions of a finite number of generalized coherent states, which can be used to express non-classical effects such as oscillations in the photon number distribution, quadrature squeezing, SU(1, 1) squeezing and SU(2, 2) squeezing.Abstract:
We show that multiphoton coherent states can be expressed as linear quantum superpositions of a finite number of generalized coherent states. Quantum interferences between component states lead to appearance of non-classical effects such as oscillations in the photon number distribution, quadrature squeezing, SU(1, 1) squeezing and others.read more

Vladimír Bužek,Peter L. Knight +1 more
TL;DR: In this article, the authors discuss the quantum interference, superposition states of light and the nonclassical effects of quantum coherences between coherent states, and associate quantum correlations with quantum interference in the phase space.

Graphene coherent states
TL;DR: In this paper, the coherent states for a Dirac electron in graphene placed in a constant homogeneous magnetic field which is orthogonal to the graphene surface were derived as eigenstates of the annihilation operator with complex eigenvalues.

Comparison of quantum and semiclassical radiation theories with application to the beam maser
E.T. Jaynes,F.W. Cummings +1 more
TL;DR: In this article, it was shown that the semiclassical theory, when extended to take into account both the effect of the field on the molecules and the effects of the molecules on the field, reproduces the same laws of energy exchange and coherence properties as the quantized field theory, even in the limit of one or a few quanta in the field mode.

TL;DR: A quantitative comparison with theory suggests that the observed squeezing results from a field that in the absence of linear attenuation would be squeezed by greater then tenfold.

Coherent states for arbitrary Lie group
TL;DR: In this paper, the concept of coherent states originally closely related to the nilpotent group of Weyl is generalized to arbitrary Lie groups and its features are investigated for the simplest Lie groups.
