Optical-approximation analysis of sidewall-spacing effects on the force between two squares with parallel sidewalls
Saad Zaheer, Alejandro W. Rodriguez, Steven G. Johnson +1
Using the ray-optics approximation, we analyze the Casimir force in a two dimensional domain formed by two metallic blocks adjacent to parallel metallic sidewalls, which are separa…
Tailoring optical nonlinearities via the Purcell effect
Peter Bermel, Alejandro Rodriguez, John D. Joannopoulos +1
We predict that the effective nonlinear optical susceptibility can be tailored using the Purcell effect. While this is a general physical principle that applies to a wide variety o…
Virtual photons in imaginary time: Computing exact Casimir forces via standard numerical-electromagnetism techniques
Alejandro Rodriguez, Mihai Ibanescu, Davide Iannuzzi +2
We describe a numerical method to compute Casimir forces in arbitrary geometries, for arbitrary dielectric and metallic materials, with arbitrary accuracy (given sufficient computa…
