Contribution

It introduces a theoretical analysis of strain-dependent Casimir interactions in graphene, highlighting substrate influence and directional effects.

Findings

Strain direction significantly alters Casimir interactions.

Dielectric substrates amplify strain effects, metallic substrates weaken them.

Strain can be used to tune interactions for device applications.

Abstract

We theoretically study the strain effect on the Casimir interactions in graphene based systems. We found that the interactions between two strained graphene sheets are strongly dependent on the direction of stretching. The influence of the strain on the dispersion interactions is still strong in the presence of dielectric substrates but is relatively weak when the substrate is metallic. Our studies would suggest new ways to design next generation devices.
