O xoves 9 de xullo de 2026, Alexander O. Govorov (Department of Physics and Astronomy
Ohio University, Athens, USA) ofrecerá o seminario "Why Is Chirality So Hot in Plasmonics?
A Short Journey into Langmuir's Legacy of Plasma Oscillations and How the Term "Plasmon" Was Coined " dentro do ciclo CINBIO Seminar Programme.
Será ás 11:00 horas na Sala de Seminarios de Torre CACTI.
ABSTRACT:
Chirality, a property of structures whose mirror images cannot be superimposed [1], plays a fundamental role in biological systems and is becoming increasingly important in plasmonics and biophotonics. We investigate how symmetry breaking and plasmonic resonances govern local electromagnetic fields and hot-carrier distributions [2].
Our approach combines electromagnetic simulations with quantum and semiclassical transport theory [3], supported by spectroscopic and photoelectrical experiments. We also briefly discuss Langmuir's legacy of plasma oscillations and the enduring influence of the Drude–Sommerfeld model on modern nanoscale transport physics and hot-electron phenomena in plasmonic materials.
