Optical coherent perfect absorption and amplification in a time-varying medium - Nature Photonics The researchers show that a subwavelength film of indium tin oxide, the bulk permittivity of which is strategically modulated via optical pumping, can be dynamically tuned to act as both a non-resonan...

News from the lab! 🤩
Is it possible to switch a material from being an absorber to an amplifier just by changing the phase of light?
By treating a thin film of ITO as a time-varying medium, we achieved 400% amplification and 80% absorption within the same structure.

New preprint from our lab -
Learning Nonlinear Heterogeneity in Physical Kolmogorov–Arnold Networks: arxiv.org/abs/2601.15340

We asked what if instead of training linear weights in physical neural networks, we train nonlinear physical dynamics. We find better performance, with fewer devices.

Neuromodulation enhances dynamic sensory processing in spiking neural network models Neuromodulators allow circuits to dynamically change their biophysical properties in a context-sensitive way. In addition to their role in learning, neuromodulators have been suggested to play a role ...

New preprint! What happens if you add neuromodulation to spiking neural networks and let them go wild with it? TLDR: it can improve performance especially in challenging sensory processing tasks. Explainer thread below. 🤖🧠🧪 www.biorxiv.org/content/10.1...
