Tunable interface states between Floquet-Weyl semimetals
F. Bonasera, S. -B. Zhang, L. Privitera +1
Weyl semimetals and nodal line semimetals are characterized by linear electronic bands touching at zero-dimensional points and one-dimensional lines, respectively. Recently, it has…
Topological Burning Glass Effect
Simon Körber, Lorenzo Privitera, Jan Carl Budich +1
We reveal a topological burning glass effect, where the local response of a system exhibits a topological quantization that is enhanced by an integer due to its environmental coupl…
Backscattering off a driven Rashba impurity at the helical edge
Lorenzo Privitera, Niccolò Traverso Ziani, Inès Safi +1
The spin degree of freedom is crucial for both understanding and exploiting the particular properties of the edges of two-dimensional topological insulators. In the absence of supe…
Interacting topological frequency converter
Simon Körber, Lorenzo Privitera, Jan Carl Budich +1
We show that an interacting two-spin model subjected to two circularly polarized drives enables a feasible realization of a correlated topological phase in synthetic dimensions. Th…
Transport signatures of a Floquet topological transition at the helical edge
C. Fleckenstein, N. Traverso Ziani, L. Privitera +2
The manipulation of the helical edge states of two-dimensional topological insulators is crucial for the development of technological applications. Recently, an important step forw…
Localization, topology and quantized transport in disordered Floquet systems
Matteo M. Wauters, Angelo Russomanno, Roberta Citro +2
We investigate the transition induced by disorder in a periodically-driven one-dimensional model displaying quantized topological transport. We show that, while instantaneous eigen…
Feasible model for photo-induced interband pairing
S. Porta, L. Privitera, N. Traverso Ziani +3
Recently, it has been proposed that a mechanism for the appearance of non-equilibrium superconductivity in a resonantly driven semiconductor with repulsive interband interactions e…
Strong frequency dependence of transport in the driven Fano-Anderson model
Daniel Hetterich, Gabriel Schmitt, Lorenzo Privitera +1
We study a periodically driven central site coupled to a disordered environment. In comparison to the static model, transport features are either enhanced or reduced, depending on…
On the dynamics of Simulated Quantum Annealing in random Ising chains
Glen Bigan Mbeng, Lorenzo Privitera, Luca Arceci +1
Simulated Quantum Annealing (SQA), that is emulating a Quantum Annealing (QA) dynamics on a classical computer by a Quantum Monte Carlo whose parameters are changed during the simu…
Non-adiabatic breaking of topological pumping
Lorenzo Privitera, Angelo Russomanno, Roberta Citro +1
We study Thouless pumping out of the adiabatic limit. Our findings show that despite its topological nature, this phenomenon is not {generically} robust to non-adiabatic effects. I…
Edge states reconstruction from strong correlations in quantum spin Hall insulators
A. Amaricci, G. Sangiovanni, L. Privitera +3
We study quantum spin Hall insulators with local Coulomb interactions in the presence of boundaries using dynamical mean field theory. We investigate the different influence of the…
Quantum annealing and non-equilibrium dynamics of Floquet Chern insulators
Lorenzo Privitera, Giuseppe E. Santoro
Inducing topological transitions by a time-periodic perturbation offers a route to controlling the properties of materials. Here we show that the adiabatic preparation of a non-tri…
