Tracing topological phase transitions with X-ray absorption techniques

An international team of researchers present in Reports on Progress in Physics Original Research a numerical experiment that demonstrates the possibility to capture topological phase transitions via an x-ray absorption spectroscopy scheme. By overcoming previous energy resolution limitations, the method will enable further investigations on relevant systems for optoelectronics applications.

Attosecond core-level spectroscopy reveals real-time molecular dynamics

A team of European researchers has developed an attosecond core-level spectroscopy technique that can track the many-body molecular dynamics on its natural ultrafast timescale. Their work was benchmarked with furan, showing the power of their tool by successfully retrieving the entire history evolution of the dynamics and relaxation processes of a heterocyclic organic ring.

A novel universal light-based technique to control valley polarization in bulk materials

An ICFO team, in collaboration with international partners, publishes in Nature a new method that, for the first time, achieves valley polarization in centrosymmetric bulk materials universally, without reliance on specific materials. This “universal technique” could have significant implications for controlling and analyzing various properties of both 2D and 3D materials. Such advancements could drive […]

Researchers theoretically unveil high harmonic generation as a new source of squeezed quantum light

A team of researchers and OPTOlogic team members theoretically prove that the emitted light after a high harmonic generation (HHG) process is not classical, but quantum and squeezed. The study unveils the potential of HHG as a new source of bright entangled and squeezed light, two inherent quantum features with several cutting-edge applications within quantum […]

New analog simulators can facilitate the study of ultrafast dynamics processes

A team of researchers, including members from the Optologic team, theoretically proposes a new experimental platform based on analog simulation with atom clouds to study high-harmonic generation. This ultrafast dynamic process challenges conventional computational methods. Their simulator allows for adaptation to approach a wide range of complex phenomena, opening doors to regimes that theory and […]
