Multi‐Method Geophysical Surveys Between and Around the Kerlescan and the Manio Megalithic Alignments in Carnac (Morbihan, France)

open access: yesArchaeological Prospection, Volume 33, Issue 2, Page 499-517, April/June 2026.
ABSTRACT The Carnac alignments in Morbihan (France) are among the most famous Neolithic sites of the world. Paradoxically, they have benefited little from a thorough renewal of archaeological data over the past century. There are many reasons for this, but it is mainly because the site has been regarded more as a monument to visit and protect than as ...

Leveraging Plasmonic Nanocavity Arrays Forming Metasurfaces to Boost Second Harmonic Generation Due to Surface Effects

open access: yesAdvanced Optical Materials, Volume 14, Issue 9, 6 March 2026.
Second harmonic generation (SHG) typically requires non‐centrosymmetric crystals to be realized. Here, we experimentally demonstrate a 105‐fold boost in the SHG response from centrosymmetric materials by realizing gold nanocavity arrays forming plasmonic metasurfaces.

Boosting the Magnetic Response of a Composite Nanostructure in the Near‐Visible Region with a Fano Resonance

open access: yesAdvanced Photonics Research, Volume 7, Issue 1, January 2026.
Optical simulations of composite plasmonic split‐ring resonators show that a magnetic response can be obtained at wavelengths near the visible regime. The response is further increased by extending the geometry and enabling a Fano resonance through the coupling of magnetic dipoles.

Drones and Stones - Using UAV SfM photogrammetry to investigate petroglyph degradation of Neolithic megaliths at Cromeleque dos Almendres, Portugal. [PDF]

open access: yes, 2019
The Almendres Cromlech is the largest and most important of the Neolithic Megalithic enclosures in Portugal. The scale and significance is reflected in the presence of a series of petroglyphs on the site, which provide insight into the lives of the ...

Digital Spatial Technologies to Compose the Map of the Southeast Iberia Megalithic Phenomenon. The Case Study of Fonelas (Granada, Spain)

open access: yesArchaeological Prospection, Volume 33, Issue 1, Page 257-273, January/March 2026.
ABSTRACT Megalithic landscapes in Southeast Iberia remain unevenly and insufficiently documented, particularly in rugged areas where traditional survey methods are limited. This paper addresses this gap by applying a multiscalar approach to the megalithic necropolises of the Fardes River (Granada, Spain), with the objective of detecting, documenting ...

Strong and Weak Coupling Nanophysics with Free Electron Beams

open access: yesAdvanced Optical Materials, Volume 13, Issue 34, December 2, 2025.
This paper focuses on a short review of the study of the coupling between optical excitations at the nanometer scale, made possible by recent advances in free electron beam spectroscopies. In particular, plasmon–plasmon, plasmon–exciton, and plasmon–phonon couplings are reviewed. Abstract The work of Luis M.
