Intermolecular interactions in optical cavities: An ab initio QED study

Area of Science:

• Physical Chemistry
• Quantum Optics
• Materials Science

Background:

• Intermolecular bonds influence molecular systems despite being weaker than covalent bonds.
• Understanding and controlling intermolecular forces is key in chemistry and materials science.

Purpose of the Study:

• To investigate how strong light-matter coupling modifies intermolecular forces.
• To explore the role of electron correlation in these modified interactions.
• To propose optical cavities as a tool for manipulating molecular properties.

Main Methods:

• Theoretical investigation of light-matter interactions within an optical cavity.
• Analysis of how electromagnetic fields affect ground state properties of molecular complexes.
• Examination of electron density, dipole moments, and polarizabilities under varying cavity conditions.

Main Results:

• Strong light-matter coupling can significantly alter intermolecular interactions.
• Electron-photon correlation is essential for accurately describing these interactions.
• Cavity properties like polarization and frequency tune the stability and nature of interactions.

Conclusions:

• Optical cavities offer a novel approach to control intermolecular forces.
• This method can be used to manipulate ground state properties and solvent effects.
• Findings are applicable to molecules and materials for advanced applications.
