Stimulation of cells with electrical cues is an imperative approach to interact with biological
systems and has been exploited in clinical practices over a wide range of pathological …

In undergraduate courses on classical electromagnetism, it is taught that a perfect conductor
expels the electromagnetic (EM) field, and hence its surface is not able to support the …

Despite the rapid development of perovskite solar cells (PSCs) over the past few years, the
conversion of solar energy into electricity is not efficient enough or cost-competitive yet. The …

Frequency conversion processes, such as second-and third-harmonic generation, are
commonly realized in nonlinear optics, offering opportunities for applications in photonics …

The present status and development of strong-field nano-optics, an emerging field of
nonlinear optics, is discussed. A nonperturbative regime of light-matter interactions is …

Plasmonics has emerged as an important research field in nanoscience and
nanotechnology. Recently, significant attention has been devoted to the observation and the …

New propagation regimes for light arise from the ability to tune the dielectric permittivity to
extremely low values. Here, we demonstrate a universal approach based on the low linear …

When light interacts with metal nanostructures, it can couple to free-electron excitations near
the metal surface. The electromagnetic resonances associated with these surface plasmons …

Light scattering by small particles has a long and interesting history in physics. Nonetheless,
it continues to surprise with new insights and applications. This includes new discoveries …

Recently two emerging areas of research, attosecond and nanoscale physics, have started
to come together. Attosecond physics deals with phenomena occurring when ultrashort laser …
