Excitation dynamics and relaxation in a molecular heterodimer

Einladung Zum Physikalischen Kolloquium Excitation Dynamics and Relaxation in Molecular Aggregates and Photosynthetic Pigment-protein Complexes

Excitation Dynamics and Relaxation in Molecular Aggregates and Photosynthetic Pigment-Protein Complexes In photosynthesis the light-harvesting complexes are responsible for efficient excitation delivery to reactions centers responsible for conversion of the absorbed energy into the trans-membrane potential. This is the reason why the concept of photosynthetic antenna is widely used by describin...

Theory of molecular excitation and relaxation near a plasmonic device.

The new optical concepts currently developed in the research field of plasmonics can have significant practical applications for integrated optical device miniaturization as well as for molecular sensing applications. Particularly, these new devices can offer interesting opportunities for optical addressing of quantum systems. In this article, we develop a realistic model able to explore the va...

Excitation and relaxation dynamics in ultrafast laser irradiated optical glasses

We discuss the dynamics of ultrashort pulsed laser excitation in bulk optical silica-based glasses (fused silica and borosilicate BK7) well-above the permanent modification threshold. We indicate subsequent structural and thermomechanical energy relaxation paths that translate into positive and negative refractive index changes, compression and rarefaction zones. If fast electronic decay occurs...

Stochastic dynamics and relaxation in molecular systems

Influence of Interface Thermal Resistance on Relaxation Dynamics of Metal-Dielectric Nanocomposite Materials under Ultrafast Pulse Laser Excitation

Nanocomposite materials, including noble metal nanoparticles embedded in a dielectric host medium, are interesting because of their optical properties linked to surface plasmon resonance phenomena. For studding of nonlinear optical properties and/or energy transfer process, these materials may be excited by ultrashort pulse laser with a temporal width varying from some femtoseconds to some hund...
