Studies of the Electronic Structure of Metallocene-based Second-order Non-linear Optical Dyes
Electronic Structure Metallocene Second-order Non linear Optical Dyes
2016/5/23
This paper describes a simple orbital picture for understanding the optical transitions and the second-order nonlinear optical response of metallocene-based chromophores of the form metallocene-(pi-br...
Large Molecular Third-Order Optical Nonlinearities in Polarized Carotenoids
Carotenoids Molecular Structure Optics and Photonics Photochemistry Spectrum Analysis
2016/5/23
Garito and co-workers have suggested a mechanism to dramatically increase the second hyperpolarizability, gamma, in linear pi-electron-conjugated molecules. Polarization is introduced that leads to a ...
Most of our food, medicine, fuel, plastics and synthetic fibers wouldn’t exist without catalysts, materials that open favorable pathways for chemical reactions to run forth. And yet chemists don’t ful...
Higher-order kinetic expansion of quantum dissipative dynamics: Mapping quantum networks to kinetic networks
Higher-order kinetic expansion quantum dissipative dynamics Mapping quantum networks kinetic networks
2013/3/13
We apply a new formalism to derive the higher-order quantum kinetic expansion (QKE) for studying dissipative dynamics in a general quantum network coupled with an arbitrary thermal bath. The dynamics ...
Tracing the structure of asymmetric molecules from high-order harmonic generation
Tracing the structure asymmetric molecules high-order harmonic generation
2011/11/17
We investigate high-order harmonic generation (HHG) from asymmetric molecules exposed to intense laser fields. We show that the emissions of odd and even harmonics depend differently on the orientatio...
The inefficiency of re-weighted sampling and the curse of system size in high order path integration
statistical sampling re-weighting high-order path integrals
2011/7/10
Abstract: Computing averages over a target probability density by statistical re-weighting of a set of samples with a different distribution is a strategy which is commonly adopted in fields as divers...

Calculations of nonlinear spectra of liquid Xe. I. Third-order Raman response
nonlinear spectra liquid Xe Third-order Raman response
2001/7/17
The microscopic interactions and dynamics probed by third-order Raman spectroscopy in an atomic liquid ~Xe! are explored within the Drude oscillator model, both numerically and analytically. Many-body...
Calculations of nonlinear spectra of liquid Xe. II. Fifth-order Raman response
nonlinear spectra liquid Xe Fifth-order Raman response
2001/7/11
The polarization dependence and temporal profile of the fifth-order Raman response function and corresponding correlation function in liquid Xe are studied both analytically and numerically. Based on ...
