Contribution

It provides empirical evidence that long-range interactions enhance thermal rectification and sustain it in larger systems, overcoming previous limitations.

Findings

Long-range interactions boost rectification effect.

Rectification remains high as system size increases.

Effective in systems with equal mass and graded on-site potential.

Abstract

We provide convincing empirical evidence that long range interactions strongly enhance the rectification effect which takes place in mass graded systems. Even more importantly the rectification does not decrease with the increase of the system size. Large rectification is obtained also for the equal mass case and with graded on-site potential. These results allow to overcome current limitations of the rectification mechanism and open the way for a realistic implementation of efficient thermal diodes.
