# Rectification of Vibrational Energy Transfer in Driven Chiral Molecules

## TL;DR

This paper demonstrates that combining molecular chirality with phase-controlled driving can rectify vibrational energy transfer, with effects depending on frequency, polarization, and temperature, including at room temperature.

## Contribution

It introduces a novel method to control vibrational energy flow in chiral molecules using phase-controlled driving, supported by classical models.

## Key findings

- Rectification depends on driving frequency and phase.
- Effect persists at room temperature.
- Directionality can be controlled by polarization.

## Abstract

We show that the combination of molecular chirality and phase-controlled driving can lead to rectification of vibrational energy transfer. We demonstrate this effect using classical models of (1) a single helical chain and (2) a more realistic model of polyethylene double helix. We examine the effect of the driving frequency, polarization, and temperature on this phenomenon. Notably, we find that the direction and magnitude of the observed directionality preference depend on the driving frequency and phase, and that the effect persists at room temperature.
