Single-pump hybrid nonlinearities in transparent conductors
Wallace Jaffray, Sven Stengel, Alexandra Boltasseva +7
Low-index transparent conducting oxides have attracted significant attention because ultrafast optical excitation in these materials can induce exceptionally large temporal index g…
Analytic Inverse Design of Temporal Metamaterials via Space-Time Duality
Giuseppe Castaldi, Marino Coppolaro, Massimo Moccia +3
Temporal metamaterials, created by modulating the refractive index in time, offer powerful means of controlling wave propagation but still lack a systematic design methodology. Her…
Optical Spin Effects Induced by Phase Conjugation at a Space-Time Interface
Carlo Rizza, Alessandra Contestabile, Maria Antonietta Vincenti +5
Electromagnetic temporal boundaries, emerging when the constitutive parameters of a medium undergo abrupt temporal variations, have garnered significant interest for their role in…
All-optical polarization control in time-varying low-index films via plasma symmetry breaking
Wallace Jaffray, Sven Stengel, Alexandra Boltasseva +6
Controlling the polarization state of light with sub-picosecond speed and subwavelength precision remains a key challenge for next-generation nanophotonic devices. Conventional met…
Unconventional Magnetism, Sliding Ferroelectricity, and Magneto-Optical Kerr Effects in a Multiferroic Bilayer
Chen Xinfeng, Ding Ning, Paolo Barone +6
Antiferromagnetic (AFM) materials offer a promising platform for exploring novel couplings between altermagnetic (AM) spin-splitting and magneto-optical Kerr effect (MOKE), with po…
Linking structure and optical properties of plasmonic nanoparticles on tunable spherical surfaces
Francesco Brasili, Angela Capocefalo, Giovanni Del Monte +8
The complexation of plasmonic nanoparticles (NPs) and thermoresponsive microgels is widely exploited for applications, but a microscopic description of the mechanisms governing the…
