Hidden optical nonlinearities in linear spectra of quantum emitter arrays
Sricharan Raghavan-Chitra, Arghadip Koner, Joel Yuen-Zhou
Classical optical frameworks such as the discrete dipole approximation (DDA) assume that the linear spectrum of coupled quantum emitters can be computed solely from the linear susc…
Permutationally symmetric molecular aggregates
Sricharan Raghavan-Chitra, Arghadip Koner, Joel Yuen-Zhou
Linear optical spectra of molecular aggregates are often approximated by classical optics methods such as the discrete-dipole approximation (DDA), coherent exciton scattering (CES)…
Dynamical Drexhage Effect: Amplified Emission in Time-Modulated Electromagnetic Environments
Juan Carlos Obeso Jureidini, Michael Reitz, Piper Fowler-Wright +4
We investigate the effect of nonrelativistic motion on the emission dynamics of a dipole emitter moving next to a reflecting interface. Within the formalism of macroscopic QED, we…
High-Q microresonators unveil quantum rare events
Sricharan Raghavan-Chitra, Arghadip Koner, Joel Yuen-Zhou
Classical linear optics posits that at sufficiently low intensities, light propagation in dielectric media is governed solely by their linear susceptibilities. Here, we demonstrate…
Quantum theory of surface lattice resonances
Michael Reitz, Stephan van den Wildenberg, Arghadip Koner +2
The collective interactions of nanoparticles arranged in periodic structures give rise to high- in-plane diffractive modes known as surface lattice resonances. While these reson…
Hidden nonlinear optical susceptibilities in linear polaritonic spectra
Arghadip Koner, Joel Yuen-Zhou
Linear spectra of molecular polaritons formed by molecules coupled to a microcavity photon mode are usually well described by classical linear optics, raising the question of w…
CUT-E as a expansion for multiscale molecular polariton dynamics
Juan B. Pérez-Sánchez, Arghadip Koner, Sricharan Raghavan-Chitra +1
Molecular polaritons arise when the collective coupling between an ensemble of molecules and an optical mode exceeds individual photon and molecular linewidths. The complexity…
Nonlinear semiclassical spectroscopy of ultrafast molecular polariton dynamics
Michael Reitz, Arghadip Koner, Joel Yuen-Zhou
We introduce a theoretical framework that allows for the systematic and efficient description of the ultrafast nonlinear response of molecular polaritons, i.e., hybrid light-matter…
When do molecular polaritons behave like optical filters?
Kai Schwennicke, Arghadip Koner, Juan B. Pérez-Sánchez +4
This review outlines several linear optical effects featured by molecular polaritons arising in the collective strong light-matter coupling regime. Under weak laser irradiation and…
Linear response of molecular polaritons
Joel Yuen-Zhou, Arghadip Koner
In this article, we show that the collective light-matter strong coupling regime, where molecular emitters couple to the photon mode of an optical cavity, can be mapped to a qu…
Thermodynamic coupling of reactions via few-molecule vibrational polaritons
Arghadip Koner, Matthew Du, Sindhana Pannir-Sivajothi +2
Interaction between light and molecular vibrations leads to hybrid light-matter states called vibrational polaritons. Even though many intriguing phenomena have been predicted for…
Chiral edge waves in a dance-based human topological insulator
Matthew Du, Juan B. Pérez-Sánchez, Jorge A. Campos-Gonzalez-Angulo +10
Topological insulators are insulators in the bulk but feature chiral energy propagation along the boundary. This property is topological in nature and therefore robust to disorder.…
Collective dynamics Using Truncated Equations (CUT-E): simulating the collective strong coupling regime with few-molecule models
Juan B. Pérez-Sánchez, Arghadip Koner, Nathaniel P. Stern +1
The study of molecular polaritons beyond simple quantum emitter ensemble models (e.g., Tavis-Cummings) is challenging due to the large dimensionality of these systems (the number o…
Temperature dependent maximization of work and efficiency in a degeneracy assisted quantum Stirling heat engine
Sarbani Chatterjee, Arghadip Koner, Sohini Chatterjee +1
We propose a quantum Stirling heat engine with an ensemble of harmonic oscillators as the working medium. We show that the efficiency of the harmonic oscillator quantum Stirling he…
