Geometric Theory of Lattice Vibrations and Specific Heat

We discuss, from a geometric standpoint, the specific heat of a solid. This is a classical subject in solid state physics which dates back to a pioneering work by Einstein (1907) and its refinement by Debye (1912). Using a special quantization of crystal lattices and calculating the asymptotic of the integrated density of states at the bottom of the spectrum, we obtain a rigorous derivation of ...

Micro-Raman spectroscopic visualization of lattice vibrations and strain in He- implanted single-crystal LiNbO3

Scanning micro-Raman spectroscopy has been utilized to image and investigate strain in He-implanted congruent LiNbO3 samples. By using abruptly patterned implanted samples, we show that the spatial twodimensional mapping of the Raman spectral peaks can be used to image the strain distribution and determine its absolute magnitude. We demonstrate that both shortand long-range length-scale in-plan...

Anisotropic anharmonicity of lattice and molecular vibrations of 1,2,4,5 tetrabromobenzene determined by piezomodulated Raman spectroscopy

Coherent Anti-Stokes Raman Scattering Microscopy: Instrumentation, Theory, and Applications

Coherent anti-Stokes Raman scattering (CARS) microscopy permits vibrational imaging with high-sensitivity, high speed, and three-dimensional spatial resolution. We review recent advances in CARS microscopy, including experimental design, theoretical understanding of contrast mechanisms, and applications to chemical and biological systems. We also review the development of multiplex CARS microsp...
