Research interests
My research is focused on quantum many-body systems with scarring. This phenomenon is characterised by the presence of special eigenstates at high energy. Despite being in the middle of the spectrum, these states have some unusual properties such as low entanglement entropy and expectation values of operators far from the predictions of the canonical ensemble. These rare non-thermal states coexist with a large number of chaotic eigenstates. They have been found in a wide range of physical systems such as Rydberg atoms or strongly correlated electrons. Their presence can lead to some desirable properties for the system, like long coherence times when quenching from some specific simple states. My work is aimed at understanding the condition leading to the emergence of these states and how their unusual properties can be used.
