A team of researchers, including Optologic team members, has produced non-classical quantum states of light, known as generalized coherent state superpositions (GCSS), and successfully used them to drive second harmonic generation —a nonlinear optical process. The introduction of optical GCSS in the realm of nonlinear quantum optics opens new paths in quantum information science, attosecond […]
Researchers establish a robust theoretical description of many-body localization (MBL) —a phenomenon that prevents quantum many-body systems from reaching equilibrium. This advancement enables understanding and demonstrating MBL in a wider range of quantum many-body systems.
Researchers experimentally demonstrate that the light emitted after a high harmonic generation process in semiconductors is entangled and squeezed, two unmistakable signs of quantum light.
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.
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.
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 […]
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 […]
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.
