Qubit-oscillator relationships in the open quantum Rabi model: the role of dissipation
G. Di Bello, L. M. Cangemi, V. Cataudella +3
Using a dissipative quantum Rabi model, we study the dynamics of a slow qubit coupled to a fast quantum harmonic oscillator interacting with a bosonic bath from weak to strong and…
First-order transitions in spin chains coupled to quantum baths
C. A. Perroni, A. De Candia, V. Cataudella +2
We show that tailoring the dissipative environment allows to change the features of continuous quantum phase transitions and, even, induce first order transitions in ferromagnetic…
Tunable spin and orbital Edelstein effect at (111) LaAlO/SrTiO interface
Mattia Trama, Vittorio Cataudella, Carmine Antonio Perroni +2
Converting charge current into spin current is one of the main mechanisms exploited in spintronics. One prominent example is the Edelstein effect, namely the generation of a magnet…
Signatures of Dissipation Driven Quantum Phase Transition in Rabi Model
G. De Filippis, A. de Candia, G. Di Bello +6
By using worldline Monte Carlo technique, matrix product state and a variational approach à la Feynman, we investigate the equilibrium properties and relaxation features of the dis…
Electric polarization and its quantization in one-dimensional non-Hermitian chains
Jinbing Hu, Carmine Antonio Perroni, Giulio De Filippis +3
We generalize the modern theory of electric polarization to the case of one-dimensional non-Hermitian systems with line-gapped spectrum. In these systems, the electronic position o…
Gate tunable anomalous Hall effect: a Berry curvature probe at oxides interfaces
Mattia Trama, Carmine Antonio Perroni, Vittorio Cataudella +2
The characterization and the experimental measurement of the Berry curvature in solids have become an increasingly relevant task in condensed matter physics. We present the theoret…
