ABSTRACT Light amplification in photonic time crystals (PTCs), enabled by their momentum bandgap, is a well‐established phenomenon. However, prior research has predominantly focused on achieving a substantial gap, whereas the controlled manipulation of light properties remains largely unexplored. Here, we exploit spatially …

Based on an effective two-band model and using the fluctuation-exchange (FLEX) approach, we explore spin fluctuations and unconventional superconducting pairing in Fe-based layer superconductors. It is elaborated that one type of interband antiferromagnetic (AF) spin fluctuation stems from the interband Coulomb repulsion, …
