Quantum Thermodynamics We are interested in energy transport at small scales taking place when a small systems is interacting with several environemnts. In such conditions small quantum systems may act as thermal machines or, as in the case or trapped ions, anomalous transpost of energy takes place between two reservoirs.

Quantum Correlations, such as Entanglement and Discord are at the core of Quantum Physics. Their analysis in continuous variable systems, as interacting non-resonant harmonic oscillators is one of our interests.
