Diagrammatic Schemes for Nonlinear Optical Interactions

open access: yesJournal of Raman Spectroscopy, EarlyView.
Conventional diagrammatic approaches (blue frames in the figure) to semi‐classical nonlinear optical interactions emphasize either the bra and ket matter states (double‐sided Feynman diagrams and Liouville pathways) or the frequencies of the bra and ket radiative processes between energy levels (Albrecht notation). We propose a field‐type modification (

Coherent Terahertz Hyper‐Raman Spectroscopy

open access: yesJournal of Raman Spectroscopy, EarlyView.
In this paper, we review our recent discovery of a novel nonlinear effect in the terahertz frequency range, which we have termed terahertz hyper‐Raman (THYR) spectroscopy. This technique shares many characteristics with conventional hyper‐Raman spectroscopy but is applied within the THz spectrum.

Simulated Infrared and Raman Spectra of Phosphorus Allotropes

open access: yesJournal of Raman Spectroscopy, EarlyView.
In this computational work, we have systematically investigated the vibrational properties of white γ$$ \gamma $$, white β$$ \beta $$, fibrous red, violet and black phosphorus allotropes by simulating their infrared (IR) and Raman spectra by means the density functional theory (DFT) level.

Gazeau- Klouder Coherent states on a sphere

open access: yesIranian Journal of Physics Research, 2019
In this paper, we construct the Gazeau-Klauder coherent states of a two- dimensional harmonic oscillator on a sphere based on two equivalent approaches.
