Autor: Mudiayi, J. Lukusa, Maurin, I., Mashimo, T., Carvalho, J. C. de Aquino, Bloch, D., Tokunaga, S. K., Darquié, B., Laliotis, A.

We report on precision spectroscopy of sub-wavelength confined molecular gases. This was obtained by rovibrational selective reflection of $\mathrm{NH_3}$ and $\mathrm{SF_6}$ gases using a quantum cascade laser at $\lambda\approx 10.6 \mu m$. Our tec

Velocity preserving transfer between highly excited atomic states: Black Body Radiation and Collisions

Autor: Carvalho, J. C. de Aquino, Maurin, I., Failache, H., Bloch, D., Laliotis, A.

We study the excitation redistribution from cesium $7\mathrm{P}_{1/2}$ or $7\mathrm{P}_{3/2}$ to neighboring energy levels by Black Body Radiation (BBR) and inter atomic collisions using pump-probe spectroscopy inside a vapor cell. At low vapor densi

Sequential Topological Representations for Predictive Models of Deformable Objects

Autor: Antonova, Rika, Varava, Anastasiia, Shi, Peiyang, Carvalho, J. Frederico, Kragic, Danica

Deformable objects present a formidable challenge for robotic manipulation due to the lack of canonical low-dimensional representations and the difficulty of capturing, predicting, and controlling such objects. We construct compact topological repres

Free Space of Rigid Objects: Caging, Path Non-Existence, and Narrow Passage Detection

Autor: Varava, Anastasiia, Carvalho, J. Frederico, Kragic, Danica, Pokorny, Florian T.

In this work we propose algorithms to explicitly construct a conservative estimate of the configuration spaces of rigid objects in 2D and 3D. Our approach is able to detect compact path components and narrow passages in configuration space which are
