Fundamental Principles of Thermoplasmonics

Thermoplasmonic physics can be understood from different points of view (Matthew Pelton in Introduction to metal-nanoparticle plasmonics. Wiley, p 275, 2013 [1]; Besteiro et al. in ACS Photonics 4:2759–2781, 2017 [2]; Sio in Active plasmonic nanomaterials. CRC Press, Taylor & Francis Group, LLC, 2016 [3]; Camargo and Cortes in Plasmonic catalysis from fundamentals to applications. Wiley, 2021 [4]; Cunha et al. in Adv Opt Mater 8, 2020 [5]). A quantum–mechanical microscopic description defines plasmons as the collective oscillations of conduction electrons. Within this framework, plasmons manifest as charge-density waves, oscillating against a background of positive charge from atomic nuclei.
