Chiral vibrational modes and vibrational circular dichroism

Xuecheng Tao, Clà udia Climent, Ethan Abraham +2

The recent interest in chiral phonons in a variety of physical phenomena and their hypothesized role in the chiral-induced spin selectivity effect [Phys. Rev. Research, 5, L022039…

Rectification of Vibrational Energy Transfer in Driven Chiral Molecules

Jichen Feng, Ethan Abraham, Joseph E. Subotnik +1

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 classica…

Nuclear Angular Momentum Generation in Thermally Driven Chiral Systems

Jichen Feng, Ethan Abraham, Joseph Subotnik +1

The appearance of angular momentum in the nuclear motion of molecular systems lacking inversion symmetry under imposed thermal gradients presents a novel mechanism with potential i…

Quantifying the Chirality of Vibrational Modes in Helical Molecular Chains

Ethan Abraham, Abraham Nitzan

Chiral phonons have been proposed to be involved in various physical phenomena, yet the chirality of molecular normal modes has not been well defined mathematically. Here we examin…

Molecular chirality quantification: Tools and benchmarks

Ethan Abraham, Abraham Nitzan

Molecular chirality has traditionally been viewed as a binary property where a molecule is classified as either chiral or achiral, yet in the recent decades mathematical methods fo…
