6 -We are building the first quantum simulator based on ultracold atoms in Galicia. The platform will use ultracold dysprosium gases to perform quantum simulation of strongly correlated matter. Achieving this goal requires precise control of magnetic fields for laser cooling, trapping, and manipulation of atomic interactions.
7 -This project focuses on the development of magnetic field setup and PID-based current stabilization electronics for this new experimental platform.

9 -The student will be involved in:
10 -
11 -* Designing and characterizing PID feedback systems for precise current and magnetic field control.
12 -* Constructing and testing magnetic field coils and associated electronics for laser cooling and trapping of dysprosium atoms.
13 -* Measuring magnetic field stability, homogeneity, and overall system performance.
14 -* Participating in scientific discussions within an international research team.
15 -
16 -This work will contribute directly to the construction of Galicia’s first cold-atom quantum simulator and provide hands-on experience in experimental quantum technologies, atomic physics, and advanced instrumentation.
6 +The unobserved transition b → sττ is a promising probe to perform Lepton Flavour Universality tests and search for possible New Physics effects. In this project, the selected student will investigate signal and background characteristics in the decay Λb⁰ → pKτ⁺τ⁻ and develop strategies to maximize background rejection while preserving signal efficiency. The work will involve the use of modern machine-learning techniques, including BDTs, Neural Networks, and hyperparameter optimization tools such as Optuna, applied to realistic LHCb datasets.
