Paper accepted by Physical Review B

​Our paper entitled "Lumped model for rotational modes in phononic crystals" was accepted by PRB. Congratulations to Pai! In this work, we developed a lumped model that can be used to describe the local rotations in phononic crystlas. The model is based on the mass-spring harmonic system, which is simple and is able to capture the essence of physics of the rotational modes.
