Abstract: Plasmonic nanosystems are typically used in optical experiments to concentrate electromagnetic energy into sub-wavelength volumes. In this context, metal-dielectric-metal (MDM) nanosystems provide an attractive geometry for achieving strong field enhancement and mode confinement on a… read more here.

Abstract: The local distance ladder estimate of the Hubble constant (H0) is important in cosmology, given the recent tension with the early universe inference. We estimate H0 from the Type Ia supernova (SN Ia) distance ladder,… read more here.

DOI: 10.1093/mnras/stw3278
Abstract: We aim to study the optical and near-infrared linear polarimetric properties of a sample of young M7-L7 dwarfs ($\approx$1-500 Myr) with spectroscopic signatures of low- and intermediate-gravity atmospheres. We collected optical ($RIZ$) and near-infrared ($YJHK_{\rm… read more here.

DOI: 10.1103/physrevlett.130.186901
Abstract: Polarizing electron beams using light is highly desirable but exceedingly challenging, as the approaches proposed in previous studies using free-space light usually require enormous laser intensities. Here, we propose the use of a transverse electric… read more here.
