SmallTalks [about Nanoscience] Ultrastrong light-matter coupling

Welcome to a seminar in the series SmallTalks [about Nanoscience] arranged by the Excellence Initiative Nano​
Adriana Canales Ramos from Nano and Biophysics Lab, Department for Physics will talk about Ultrastrong light-matter coupling. The title for the second part of this seminar will be announced soon.

Light interacts with matter all the time. This interaction allows us to see, study and even control and change the world. Most of those interactions are weak and involve a non-reversible exchange of energy.

For example, a material can absorb incoming light and then use that energy for something else. But in some cases, the light and matter can exchange energy reversibly. This means that the electromagnetic field can give energy to the material, which can give it back to the electromagnetic field, and so on and so forth. When this happens, we say that light and matter are strongly coupled. Moreover, if the energy exchange rate is of more than 10% the usual frequency at which the material absorbs light, we say that light and matter are ultrastrongly coupled.


In this popular science talk, I will go through the basics of the response of materials to light and the different regimes of light-matter

interaction: weak, strong and ultrastrong coupling. For each regime, I will describe some interesting phenomena that can be observed.

Additionally, I will cover some exciting new results we have been working on recently.
