Single acquisition reconstruction of nonlinear susceptibility and Raman tensors at the diffraction limit
Volodymyr Multian, Luigi Bonacina, Jérémie Teyssier
Raman spectroscopy and Second Harmonic Generation (SHG) are complementary, non-destructive techniques that provide rich and distinct insights into the structural and electronic pro…
Ultra-high THz-field-confinement at LaAlO3 twin walls
Jakob Wetzel, Javier Taboada-Gutiérrez, Matthias Roeper +13
The control and steering of light at nanometre length scales is crucial for the development of both fundamental science and nanophotonic technologies. Recent advancements have been…
Edge polaritons at metal-insulator boundaries in a phase separated correlated oxide
Weiwei Luo, Adrien Bercher, Claribel Dominguez +4
Correlated transition metal oxides, such as cuprates, nickelates, and manganites, are typically considered "bad metals", where high electromagnetic losses suppress the conventional…
Non-Fermi liquid quasiparticles in strain-tuned Sr2RuO4
A. Hunter, C. Putzke, F. B. Kugler +23
Interacting electrons can form metallic states beyond the Fermi liquid paradigm, a conceptual frontier of many-body physics mainly explored via bulk thermodynamics and transport. I…
