Quantum communication is central to future secure networks and the quantum internet. While most implementations rely on polarization entanglement, limited to two-dimensional encoding, high-dimensional states, e.g., based on the orbital angular momentum (OAM) of light, enable richer Hilbert spaces, higher information rates, enhanced security, and increased robustness to noise. This project aims to advance high-dimensional […]
ObjectiveDevelop a planar micro‑TEG using ultrathin (~70–100 nm) Si films, CMOS‑compatible, fabricated on Si-on-insulator (SOI) substrates, to harvest low-grade waste heat for low‑power applications (µW–mW range). Device Design Utilize SOI wafers featuring a (~70-100 nm device Si layer). Pattern arrays of suspended Si membranes (tens of µm lateral dimensions) alternately doped n- and p‑type (e.g. phosphorus and […]
The integration of renewable energy sources into electricity systems brings clear benefits in sustainability, efficiency, and reduced emissions. Yet, their intermittency introduces new forms of dynamical instability. Fluctuations in renewable generation act as external perturbations that may trigger congestion, frequency deviations, voltage imbalances, and even large-scale blackouts, as observed in Spain in April 2025. Ensuring […]
The implementation of renewable energy resources into electricity pools, replacing the traditional use of fossil fuels, provides well-known advantages in terms of energy efficiency and reduction of carbon footprint. These, however, come at the expense of dangers and instabilities caused to the electricity grids. The unpredictability of the renewable energy systems is a potential source […]
