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…
A Mesoscopic Ginzburg--Landau Model for Vibrational Strong Coupling Enhanced Rayleigh Scattering in Molecular Liquids
Wenxiang Ying, Abraham Nitzan
Recent experiments by Sandeep \textit{et al.} [Angew. Chem. Int. Ed. 65, e16917 (2026)] suggest that vibrational strong coupling (VSC) in molecular liquids can generate mesoscopic…
Thermal chemical reactivity in Frenkel exciton-polariton cavities
Bingyu Cui, Abraham Nitzan
Hybrid light-matter states formed under strong coupling between molecular excitations and confined electromagnetic modes provide a potential route to modify chemical properties. He…
Raman spectroscopy at metal interfaces: A numerical study of the strong coupling regime
Zeyu Zhou, Maxim Sukharev, Abraham Nitzan +1
We investigate how proximity to a metal nanostructure, particularly to a flat mirror or a cavity confined between two mirrors, affects the vibronic structure of Raman scattering si…
Excitation density controlled regimes of collective light--matter dynamics
Wenxiang Ying, Abraham Nitzan
Theoretical descriptions of collective light--matter dynamics often rely on the mean-field (MF) or single-excitation (SE) approximations, yet the parameter regimes where they apply…
Chirality-sensitive mobility and dissipation of Brownian motion on a helical landscape
Debankur Bhattacharyya, Abraham Nitzan
We study the Brownian dynamics and linear response of a particle with inertia moving in a 2-dimensional helical landscape imprinted on a cylindrical surface. In the harmonic well a…
