Incandescent temporal metamaterials
J. Enrique Vázquez-Lozano, Iñigo Liberal
Regarded as a promising alternative to spatially shaping matter, time-varying media can be seized to control and manipulate wave phenomena, including thermal radiation. Here, based…
Suppressed-scattering windows for radiative cooling applications
José M. Pérez-Escudero, Alicia E. Torres-García, Carloz Leazun +5
The scattering of light by resonant nanoparticles is a key process for enhancing the solar reflectance in daylight radiative cooling. Here, we investigate the impact of material di…
Spectrally stable thermal emitters enabled by material-based high-impedance surfaces
David Navajas, José Manuel Pérez-Escudero, Iñigo Liberal
Radiative thermal engineering with subwavelength metallic bodies is a key element for heat and energy management applications, communication and sensing. Here, we numerically and e…
Shaping the quantum vacuum with anisotropic temporal boundaries
Iñigo Liberal, J. Enrique Vázquez-Lozano
Temporal metamaterials empower novel forms of wave manipulation with direct applications to quantum state transformations. In this work, we investigate vacuum amplification effects…
Quantum antireflection temporal coatings: quantum state frequency shifting and inhibited thermal noise amplification
Iñigo Liberal, J. Enrique Vázquez-Lozano, Victor Pacheco-Peña
We investigate the quantum optical response of antireflection temporal coatings, i.e., matching temporal layers that suppress the generation of backward waves in temporal boundarie…
Electrically switchable Casimir forces using transparent conductive oxides
Tao Gong, Benjamin Spreng, Miguel Camacho +3
Casimir forces between charge-neutral bodies originate from quantum vacuum fluctuations of electromagnetic fields, which exhibit a critical dependence on material's electromagnetic…
The Effect of Epsilon-Near-Zero (ENZ) Modes on the Casimir Interaction between Ultrathin Films
Tao Gong, Inigo Liberal, Benjamin Spreng +3
Vacuum fluctuation-induced interactions between macroscopic metallic objects result in an attractive force between them, a phenomenon known as the Casimir effect. This force is the…
Radiative energy bandgap of nanostructures coupled with quantum emitters around the epsilon-near-zero (ENZ) frequency
Tao Gong, Inigo Liberal, Miguel Camacho +3
Epsilon-near-zero (ENZ) materials have been demonstrated to exhibit unique electromagnetic properties. Here we propose the concept of radiative energy bandgap for an ENZ nanopartic…
