Dynamical Crossover of the Quantum Fisher Information in the Spin-Boson Model
D. Parlato, G. Di Bello, F. Pavan +2
We investigate the dynamical quantum Fisher information of a two-level system coupled to a bosonic environment, focusing on the estimation of the qubit gap. We combine analytical c…
Local and Global Master Equations through the Lens of Non-Hermitian Physics
Grazia Di Bello, Fabrizio Pavan, Vittorio Cataudella +1
We investigate the relation between non-Hermitian Hamiltonian and Lindblad dynamics in nonequilibrium open quantum systems. Non-Hermitian models can extend phase diagrams and enabl…
Tomographic characterization of non-Hermitian Hamiltonians in reciprocal space
Francesco Di Colandrea, Fabrizio Pavan, Sarvesh Bansal +6
Non-Hermitian Hamiltonians enrich quantum physics by extending conventional phase diagrams, enabling novel topological phenomena, and realizing exceptional points with potential ap…
Quantum Fisher information as a witness of non-Markovianity and criticality in the spin-boson model
Daniele Parlato, Grazia Di Bello, Fabrizio Pavan +2
The quantum Fisher information, the quantum analogue of the classical Fisher information, is a central quantity in quantum metrology and quantum sensing due to its connection to pa…
Environment induced dynamical quantum phase transitions in two-qubit Rabi model
G. Di Bello, A. Ponticelli, F. Pavan +4
The physics of quantum states beyond thermodynamic equilibrium represents a fascinating and cutting-edge research. Using numerical state-of-the-art approaches, we observe dynamical…
