Mixed-order semiclassical dynamics in coherent state representation: The connection between phonon sidebands and guest-host dynamics
The formalism of mixed-order semiclassical molecular dynamics in coherent state representation is developed and applied to calculations of quantum time correlation functions in extended systems. The… Expand
Temperature induced mobility and recombination of atomic oxygen in crystalline Kr and Xe. I. Experiment
Recombinant molecular spectra of O2 in crystalline Kr and Xe, obtained from sudden recombination induced by laser pumping of the predissociative B state, and by adiabatic recombination induced… Expand

We investigate electronic devices consisting of individual, metallic, single-walled carbon nanotubes contacted by Pt electrodes in a field effect transistor configuration, focusing on improvements to… Expand
Surface-enhanced Raman trajectories on a nano-dumbbell: transition from field to charge transfer plasmons as the spheres fuse.
By taking advantage of the tensor nature of surface-enhanced Raman scattering (SERS), we track trajectories of the linker molecule and a CO molecule chemisorbed at the hot spot of a nano-dumbbell… Expand
Visualizing vibrational normal modes of a single molecule with atomically confined light
The internal vibrations of molecules drive the structural transformations that underpin chemistry and cellular function. While vibrational frequencies are measured by spectroscopy, the normal modes… Expand
Vibrational coherence of I2 in solid Kr.
Time-resolved coherent anti-Stokes Raman scattering, with a resolution of 20 fs, is used to prepare a broadband vibrational superposition on the ground electronic state of I2 isolated in solid Kr.… Expand

- 5 April 2004
Pump-probe measurements of I2 in solid Ar are reported and analyzed to extract a description of cage response to impulsive excitation, from the gentle kick, up to the breaking point. The most… Expand
Vibrational self-consistent field approach to anharmonic spectroscopy of molecules in solids: Application to iodine in argon matrix
An extension of the vibrational self-consistent field (VSCF) method is developed for quantitative calculations of molecular vibrational spectroscopy in a crystalline solid environment. The approach… Expand
Condensed phase spectroscopy from mixed‐order semiclassical molecular dynamics: Absorption, emission, and resonant Raman spectra of I2 isolated in solid Kr
A method for spectral simulations in systems of very large dimensionality via semiclassical molecular dynamics is introduced and applied to the spectroscopy of iodine isolated in solid Kr, as a… Expand
Ultrafast pump-probe force microscopy with nanoscale resolution
We perform time-resolved pump-probe microscopy measurements by recording the local force between a sharp tip and the photo-excited sample as a readout mechanism for the material's nonlinear… Expand
