They also lead to practical technological applications for timekeeping, geodesy, and quantum-enabled sensors in general. \r\n\r\nOne promising avenue to reach higher sensitivities is to use state-of-the-art optimal quantum control techniques. Those techniques allow us to search for the fastest, the most efficient, and the most reliable controls to perform operations in quantum systems or even to solve more abstract problems, such as looking for the operations that generate the optimal probe state for a quantum sensor and even the design of sensing protocols, thus fully exploiting the potentiality of current and future experimental setups.\r\n\r\nIn this talk, I will discuss our recent advances in quantum control techniques and how these can impact different systems of interest, in particular, some exciting new analytical results for two-photon transitions and a general Quantum Control theory to optimize arbitrary computable figures of merit. Those systems of interest that will be discussed include entanglement-enhanced atomic clocks operating with extreme spin squeezed states and Dicke states, a recently proposed atomic interferometer where all degrees of freedom are fully confined called the Tractor Atomic Interferometer, and gyroscopes based on nitrogen-vacancy color centers in diamonds. \r\n\r\nBio: Sebasti\u00e1n C.

These ultra-cold Bose-Fermi mixtures are fundamentally different from degenerate gases with only bosons or fermions. They not only show an enriched phase diagram, but also a fundamental instability due to energetic considerations coming from the Pauli exclusion principle. Inspired by this activity in the physics community, recently we started exploring the mathematical theory of Bose-Fermi mixtures. One of the main challenges is understanding the physical scales of the system that allow for suitable analysis. We will describe how we overcame this challenge by identifying a novel scaling regime in which the fermion distribution behaves semi-clasically, but the boson field remains quantum-mechanical. In this regime, the bosons are much lighter and more numerous than the fermions.
