Charge and spin qubits in interacting quantum dots coupled to Rashba-active leads
Grazia Di Bello, Fabrizio Pavan, Mattia Trama +3
We present a unified study of charge and spin qubits encoded in a single interacting quantum dot tunnel-coupled to Rashba fermionic leads. The dot is described by an Anderson impur…
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…
Single particle dynamical signature of topology induced by single mode cavities in Su-Schrieffer-Heeger chain
Fabrizio Pavan, Grazia Di Bello, Giulio De Filippis +1
Witnessing and tracking topological phase transitions induced by interactions with the environment is a crucial challenge. Among the various experimental approaches to detect topol…
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…
Boson-fermion pairing and condensation in two-dimensional Bose-Fermi mixtures
Leonardo Pisani, Pietro Bovini, Fabrizio Pavan +1
We consider a mixture of bosons and spin-polarized fermions in two dimensions at zero temperature with a tunable Bose-Fermi attraction. By adopting a diagrammatic T-matrix approach…
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…
Witnessing Environment Induced Topological Phase Transitions via Quantum Monte Carlo and Cluster Perturbation Theory Studies
F. Pavan, A. de Candia, G. Di Bello +4
Many-body interactions play a crucial role in quantum topological systems, being able to impact or alter the topological classifications of non-interacting fermion systems. In open…
Boson thermodynamics in the gravity field
Loris Ferrari, Fabrizio Pavan
A uniform force like the weight has been shown to forbid Bose-Einstein condensation (BEC), due to the discreteness of the Airy spectrum, resulting from the weight. We show that BEC…
