About this Research Topic
Plasmonic nanosystems have provided the possibility to macroscopically probe effects that are generally confined to the microscopic realm, enabling phenomena that go beyond classical electrodynamics. Together with the continuous developments in nanofabrication and measurement techniques, this has brought nanoplasmonics at the center of an increasing number of novel and groundbreaking applications in medicine, information processing, energy harvesting and sensing. A huge effort has thus been devoted in the past decade in modeling and experimentally probing nonlocal, nonlinear and quantum optical effects, pushing plasmonics into unexplored territory.
The next decade represents then a great opportunity to explore quantum-enabled optical applications. Novel materials, nanofabrication capabilities, measurement techniques, theoretical models and numerical approaches allow in fact today a new undertake of the biggest challenges in nanophotonics, providing a concrete route to highly effective miniaturized low-cost optical devices through the inclusion of key plasmonic elements. In particular, plasmonic-enabled light-matter interaction at the atomic scale could unlock unprecedented sensing capabilities with huge impacts in medicine and environmental monitoring; while microscopic nonlinear plasmonics could lead to the long-sought control of photon flows at the nanoscale, leading to a new technological paradigm for next generation of information processing devices. Plasmonics is indeed the catalyzer of this innovation process and a fundamental understating of microscopic light-matter dynamics beyond the linear and local effects is the prerequisite for its unraveling.
The aim of this Research Topic is to cover recent trends and developments in nanoplasmonics, focusing on fundamental aspects and their applications. Themes may include, but are not limited to:
