Spatiotemporal symmetries and energy-momentum conservation in uniform spacetime metamaterials
Iñigo Liberal, Antonio Ganfornina-Andrades, J. Enrique Vázquez-Lozano
Spacetime metamaterials (ST-MMs) are opening new regimes of light-matter interactions based on the breaking of temporal and spatial symmetries, as well as intriguing concepts assoc…
Symmetries and conservation of spin angular momentum, helicity, and chirality in photonic time-varying media
Mohsen Mohammadi Jajin, J. Enrique Vázquez-Lozano, Iñigo Liberal
Polarization-dependent dynamical properties of light as the spin angular momentum (SAM), helicity, and chirality are conserved quantities in free-space. Despite their similarities…
A Review on the Scientific and Technological Breakthroughs in Thermal Emission Engineering
J. Enrique Vázquez-Lozano, Iñigo Liberal
The emission of thermal radiation is a physical process of fundamental and technological interest. From different approaches, thermal radiation can be regarded either as one of the…
Can thermal emission from time-varying media be described semiclassically?
Iñigo Liberal, J. Enrique Vázquez-Lozano, Antonio Ganfornina-Andrades
Time-varying media, i.e., materials whose properties dynamically change in time, have opened new possibilities for thermal emission engineering by lifting the limitations imposed b…
Quantum vacuum amplification in time-varying media with arbitrary temporal profiles
Antonio Ganfornina-Andrades, J. Enrique Vázquez-Lozano, Iñigo Liberal
In this work we address quantum vacuum amplification effects in time-varying media with an arbitrary time-modulation profile. To this end, we propose a theoretical formalism based…
A tutorial on the conservation of momentum in photonic time-varying media
Angel Ortega-Gomez, Michaël Lobet, J. Enrique Vázquez-Lozano +1
Time-varying media break temporal symmetries while preserving spatial symmetries intact. Thus, it represents an excellent conceptual framework to investigate the fundamental implic…
Enhanced excitation and readout of plasmonic cavity modes in NPoM via SiN waveguides for on-chip SERS
J. Enrique Vázquez-Lozano, Jeremy J. Baumberg, Alejandro Martínez
Metallic nanoparticle-on-a-mirror (NPoM) cavities enable extreme field confinement in sub-nm gaps, leading to unrivaled performance for nonlinear processes such as surface-enhanced…
Towards Chiral Sensing and Spectroscopy Enabled by All-Dielectric Integrated Photonic Waveguides
J. Enrique Vázquez-Lozano, Alejandro Martínez
Chiral spectroscopy is a powerful technique that enables to identify the chirality of matter through optical means. So far, experiments to check the chirality of matter or nanostru…
Classical Emergence of Intrinsic Spin-Orbit Interaction of Light at the Nanoscale
J. Enrique Vázquez-Lozano, Alejandro Martínez
Traditionally, in macroscopic geometrical optics intrinsic polarization and spatial degrees of freedom of light can be treated independently. However, at the subwavelength scale th…
Topological transitions in spin interferometers
Henri Saarikoski, J. Enrique Vázquez-Lozano, José Pablo Baltanás +3
We show that topological transitions in electronic spin transport are feasible by a controlled manipulation of spin-guiding fields. The transitions are determined by the topology o…
