Unveiling the mixed nature of polaritonic transport: From enhanced diffusion to ballistic motion approaching the speed of light

  title={Unveiling the mixed nature of polaritonic transport: From enhanced diffusion to ballistic motion approaching the speed of light},
  author={M. Balasubrahmaniyam and Arie Simkovich and Adina Golombek and Guy Ankonina and Tal Schwartz},
In recent years it has become clear that the transport of excitons and charge carriers in molecular systems can be enhanced by coherent coupling with photons, giving rise to the formation of hybrid excitations known as polaritons. Such enhancement has far-reaching technological implications, however, the enhancement mechanism and the transport nature of these composite light-matter excitations in such systems still remain elusive. Here we map the ultrafast spatiotemporal dynamics of surface…

Disorder-enhanced transport in a chain of lossy dipoles strongly coupled to cavity photons

We study the interplay between disorder and light-matter coupling by considering a disordered one-dimensional chain of lossy dipoles coupled to a multimode optical cavity, through a microscopically



Magneto-transport controlled by Landau polariton states

Hybrid excitations, called polaritons, emerge in systems with strong light–matter coupling. Usually, they dominate the linear and nonlinear optical properties with applications in quantum optics.

Microcavity-like exciton-polaritons can be the primary photoexcitation in bare organic semiconductors

Strong-coupling between excitons and confined photonic modes can lead to the formation of new quasi-particles termed exciton-polaritons which can display a range of interesting properties such as

Theory for polariton-assisted remote energy transfer

Strong-coupling between light and matter produces hybridized states (polaritons) whose delocalization and electromagnetic character allow for novel modifications in spectroscopy and chemical

High-speed flow of interacting organic polaritons

It is demonstrated that polaritons formed by the hybridization of organic excitons with a Bloch surface wave are able to propagate for hundreds of microns showing remarkable third-order nonlinear interactions upon high injection density.

Uncoupled Dark States Can Inherit Polaritonic Properties.

Here it is theoretically demonstrate that dark states can have a delocalized character, which is inherent to polaritons, despite the fact that they do not have a photonic component.

Energy relaxation pathways between light-matter states revealed by coherent two-dimensional spectroscopy

Coupling matter excitations to electromagnetic modes inside nano-scale optical resonators leads to the formation of hybrid light-matter states, so-called polaritons, allowing the controlled

Unusual dynamical properties of disordered polaritons in microcavities

The collective light-matter interaction in microcavities gives rise to the intriguing phenomena of cavity-mediated transport that can potentially overcome the Anderson localization. Yet, an accurate

Cavity-enhanced transport of excitons.

We show that exciton-type transport in certain materials can be dramatically modified by their inclusion in an optical cavity: the modification of the electromagnetic vacuum mode structure introduced

Enhanced Charge Transport in Two-Dimensional Materials through Light-Matter Strong Coupling.

The optical and electrical measurements of strongly coupled WS2 suggest an enhancement of electron transport at room temperature and a clear correlation in the effective mass of the polaritonic state and Schottky barrier height indicates a collective nature of light-matter interaction.

Manipulating matter by strong coupling to vacuum fields

The remarkable and still somewhat mysterious implications of this “strong-coupling” regime, with manifestations ranging from enhanced charge transport to site-selective chemical reactivity across a range of molecular and solid-state materials, are reviewed.
