Dynamical Casimir effects: The need for nonlocality in time-varying dispersive nanophotonics
The authors study the role of material nonlocality (spatial dispersion) in dynamical Casimir effects in time-varying frequency-dispersive nanophotonic systems. They theoretically demonstrate that nonlocality regularizes the behavior of these systems by correcting their asymptotic response for large wavevectors and leads to physical effects missed by local models, including a significant …
