TLDR
In this paper, the non-equilibrium internal state of a target, generated by the scattering of microscopic probes (neutrons, X-rays, light atoms) from the target ions, is discussed according to a quantum version of the Huygens diffraction principle.About:

Light emission from impurity states in solids: conventional and coherent phonon descriptions
TL;DR: In this paper, the authors derived the expression for the luminescence intensity using the coherent phonon description for the displaced oscillator (excited impurity) in a consequent way.

Coherent states of phonons in the polarons problem: Optical transitions of the large polaron at rest
TL;DR: In this article, the authors considered the problem of an electron trapped inside a crystal and linearly interacting with crystal phonons of small wavevector, and recognized that the cloud of virtual phonons generated around the electron, either via the Frohlich coupling or via the deformation potential interaction, is recognized to have the composition of a coherent state.

Signatures of phonon coherent states
TL;DR: In this paper, the authors compare phonon coherent states (PCS) with Fock and thermal states in two harmonic systems, the diatomic molecules and a nonconducting crystal with local centers, and analyze some of the phenomenology suggesting the cases where PCS are generated and report on their unmistakable fingerprint.

Quantum coherence among phonons generated by fast processesin elastic targets. II
TL;DR: In this article, the excited state of the quantum phonon field, generated by very fast processes, is deduced and the appropriate response functions are written in terms of these states.

Theory of Atom Scattering from Surface Phonons: Basic Concepts and Temperature Effects
TL;DR: In this paper, the Debye-Waller factor was derived and used to define experimental criteria favouring one-phonon scattering for metal and semiconductor surfaces, and an expression for the DWBA inelastic reflection coefficient was derived.

Dynamical Theory of Crystal Lattices
Max Born,Kʿun Huang +1 more
TL;DR: Born and Huang's classic work on the dynamics of crystal lattices was published over thirty years ago, and it remains the definitive treatment of the subject as mentioned in this paper. But it is not the most complete work on crystal lattice dynamics.

Coherent and incoherent states of the radiation field
TL;DR: In this article, the photon statistics of arbitrary fields in fully quantum-mechanical terms are discussed, and a general method of representing the density operator for the field is discussed as well as a simple formulation of a superposition law for photon fields.

Quantum mechanics
TL;DR: The blackbody radiation problem was solved by Max Planck as mentioned in this paper, who showed that radiation was not continuous but discrete, coming in lumps known as quanta, which became known as Planck's constant and led to the correct prediction of the blackbody spectrum.

Correlations in Space and Time and Born Approximation Scattering in Systems of Interacting Particles
TL;DR: In this paper, a natural time-dependent generalization for the well-known pair distribution function $g(mathrm{r})$ of systems of interacting particles is given, which gives rise to a very simple and entirely general expression for the angular and energy distribution of Born approximation scattering by the system.
