Energetic channels in finite many-body quantum charging
Dara Murphy, George Mihailescu, Anne Matthies +2
We examine how a finite many-body system can function as an effective charger for a single-qubit quantum battery, using the Lipkin-Meshkov-Glick model as a paradigmatic setting. As…

Spectrally local geometric response at the onset of many-body quantum chaos
George Mihailescu, Pablo M. Poggi
We introduce the spectral density of geometric response, a measure of eigenstate sensitivity across an energy spectrum. Applied to many-body quantum systems, it reveals an exponent…

Mind the Gap: Anti-Critical Quantum Metrology
George Mihailescu, Karol Gietka
Critical quantum metrology exploits the dramatic growth of the quantum Fisher information near quantum phase transitions to enhance the precision of parameter estimation. This enha…
