Dynamics of solid neon monolayers.
The dynamics of two-dimensional solid neon is investigated within the self-consistent phonon theory. Phonon frequencies and lifetimes and the one-phonon dynamic form factor are evaluated as a function of temperature and lattice spacing in the self-consistent harmonic approximation with the cubic anharmonic term added. Two-dimensional solid neon is found to be highly anharmonic. It becomes mecha...
متن کاملDiffusion of hydrogen fluoride in solid parahydrogen.
We studied diffusion of hydrogen fluoride (HF) in solid parahydrogen (pH2) around 4 K. Diffusion rates were determined from time dependence of FT-IR spectra of HF monomers. The absorption of HF monomers shows temporal decay due to dimerization reaction via diffusion. It was found that the rates are affected by the sample temperature, the initial HF concentration, and annealing of samples. The o...
متن کاملRefractive index measurements of solid parahydrogen.
Solid para-H2 is a promising gain medium for stimulated Raman scattering, due to its high number density and narrow Raman linewidth. In preparation for the design of a cw solid hydrogen Raman laser, we have made the first measurements, to our knowledge, of the index of refraction of a solid para-H2 crystal, in the wavelength range of 430-1100 nm. For a crystal stabilized at 4.4 K, this refracti...
متن کاملHigh-resolution spectroscopy and the analysis of ro-vibrational transitions of molecules in solid parahydrogen
Solid parahydrogen provides a novel matrix for isolation spectroscopy of atoms and molecules. Ro-vibrational motion of molecules embedded in solid parahydrogen is well quantized on account of the weak interactions in the crystal and of the softness of the crystal being characteristic of quantum crystals. Most of the observed spectral linewidths are one or two orders of magnitude sharper than th...
متن کاملNonlinear Optical Spectroscopy of Solid/Solid Interfaces
Nonlinear Optical Spectroscopy of Solid/Solid Interfaces Mohsen S. Yeganeh Arjun G. Yodh Three-wave mixing (3WM) spectroscopy is an exciting and relatively unexplored probe of buried solid interfaces. It possesses long penetration depths characteristic of most optical methods and intrinsic interface specificity characteristic of second-order optical processes. In this thesis we present frequenc...
