Generalized Time-Varying Drude Model for Dispersive and Lossy Modulations
Antonio Ganfornina-Andrades, J. Enrique Vázquez-Lozano, Iñigo Liberal +1
We develop a generalization of the time-varying Drude model, treating carrier density, effective mass, and collision rate as explicit functions of time. We derive expressions for p…
Synthetic crystal rotation with spacetime metamaterials
Iñigo Liberal, Alejandro Manjavacas
The interaction of light with rotating bodies has been historically limited to rotation frequencies much smaller than optical frequencies. Here, we investigate synthetic crystal ro…
Generalized Epsilon-Near-Zero Polaritons on Uniaxial Metasurfaces
Francisco Javier Alfaro-Mozaz, Iñigo Liberal
Epsilon-near-zero (ENZ) thin films facilitate strong light-matter interactions with a widespread impact in nonlinear, quantum and thermal photonics. Here, we extend the scope of th…
Mirrors without spatial boundaries
J. Enrique Vázquez-Lozano, Victor Pacheco-Peña, Iñigo Liberal
Mirrors are one of the most elementary and ubiquitous components of optical systems. They use a sharp refractive index contrast to provide the basic capability of reflecting light.…
Dispersion effects in thermal emission from temporal metamaterials: High-frequency cut-offs
Amaia Vertiz-Conde, Iñigo Liberal, J. Enrique Vázquez-Lozano
The latest breakthroughs in time-varying photonics are fueling novel thermal emission phenomena, for example, showing that the dynamic amplification of quantum vacuum fluctuations,…
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…
