Summary: Many low-electron-density Drude (LEDD) materials, such as transparent conductive oxides or nitrides, have recently attracted research interest as alternative plasmonic and extremely nonlinear thermal and optical materials due to their CMOS compatibility. However, there is currently no systematic theory to explain the electronic, thermal, and optical response of these materials. In this study, we provide an electron-dynamics model for LEDD materials, considering the complex electron-phonon and electron-electron interactions, as well as the reduced electron heat capacity compared to noble metals. Our results, focusing on indium tin oxide (ITO) as an example, can be applied to other LEDD materials easily.

Summary: Conventional plasmonic nanoantennas cannot fully exploit their scattering and absorption features simultaneously due to their overlap in the same wavelength region. However, hyperbolic meta-antennas (HMA) with spectrally separated scattering and absorption bands enable enhanced hot-electron generation and prolonged relaxation dynamics of hot carriers. By extending the plasmon-modulated photoluminescence spectrum towards longer wavelengths and controlling the tunable absorption band, HMA offers improved excitation efficiency and broader utilization of visible/NIR spectrum compared to nanodisk antennas (NDA). Therefore, rational heterostructures designed with plasmonic and adsorbate/dielectric layers in such dynamics can optimize and engineer the utilization of plasmon-induced hot carriers.

Summary: Researchers have successfully achieved a continuous time crystal by utilizing a two-dimensional array of plasmonic metamolecules supported on flexible nanowires. By illuminating the metamolecules with continuous coherent light resonant with their plasmonic mode, a spontaneous phase transition to a superradiant-like state of transmissivity oscillations was triggered, demonstrating long-range order in both space and time. This phenomenon is significant for studying dynamic classical many-body states in the strongly correlated regime and has potential applications in all-optical modulation, frequency conversion, and timing.

Summary: Time reflection is the inversion of temporal evolution of a signal that occurs when there is a uniform change in the properties of the host material. This phenomenon is similar to spatial interfaces and can be exploited for extreme wave manipulation. In this study, photonic time reflection and broadband frequency translation were observed in a switched transmission-line metamaterial, demonstrating the temporal counterpart of a Fabry-Perot cavity. This paves the way for the realization of time metamaterials and Floquet photonic crystals for advanced photon manipulation in space and time.

Summary: Optical bistability allows various optical nonlinear functions similar to electrical switches, logic gates, and memory. Free-space bistable devices have advantages in large-scale integration, but existing schemes have limitations in contrast ratio, compatibility, speed, and size. Epsilon-near-zero (ENZ) materials show ultrafast and giant optical nonlinearity, potentially overcoming these obstacles. Using indium-doped cadmium oxide as ENZ material, we demonstrate two efficient schemes for high-contrast optical bistability in deep subwavelength size based on ENZ and Berreman modes. Our work contributes to compact and ultra-fast all-optical signal processing.

Summary: Photonic time-crystals are spatially homogeneous media that exhibit periodic variations in their electromagnetic susceptibility, leading to temporal reflections and refractions of propagating waves. Free electrons in these crystals spontaneously emit radiation, with a significantly amplified emission process when associated with momentum-gap modes. Quantum interference between spontaneous emission and electron emission into the band modes suppresses the interdependent emission. Therefore, the study of free-electron physics in photonic time-crystals offers a platform to explore various exciting phenomena.

These findings are crucial for explaining the inhibition of fundamental radiative processes and for applications at the nanoscale.

Summary: In this study, we investigate light propagation in spatiotemporal photonic crystals, which are dielectric media that vary periodically in both space and time. We discover that such systems exhibit energy gaps, momentum gaps, and mixed energy-momentum gaps, where both energy and momentum can take complex values. We find a unique interplay between temporal modulation-induced exponential growth and spatial modulation-induced exponential decay, which can completely cancel each other out. Under certain conditions, these opposing forces exactly match, resulting in the collapse of the mixed energy-momentum gap to a single point, known as an exceptional point in non-Hermitian dynamics. Spatiotemporal photonic crystals possess distinct properties that could lead to new methods of controlling light propagation.

Summary: Photonic time crystals (PTCs) with periodically modulated dielectric permittivity offer new possibilities for light manipulation. In this study, we theoretically investigate the emission of light from a radiation source inside a PTC and observe exponential amplification of radiation corresponding to the momentum bandgap. The radiation linewidth narrows over time, eventually becoming monochromatic in the middle of the bandgap, which leads to the proposal of a nonresonant tunable PTC laser. Furthermore, we find that the spontaneous decay rate of an atom embedded in a PTC vanishes at the band edge due to the low density of photonic states.
