Wigner-function formalism applied to semiconductor quantum devices: Need for nonlocal scattering models
Rita Claudia Iotti, Fabrizio Dolcini, Fausto Rossi
In designing and optimizing new-generation nanomaterials and related quantum devices, dissipation versus decoherence phenomena are often accounted for via local scattering models,…
Photoexcitation of electron wave packets in quantum spin Hall edge states: effects of chiral anomaly from a localised electric pulse
Fabrizio Dolcini, Rita Claudia Iotti, Arianna Montorsi +1
We show that, when a spatially localised electric pulse is applied at the edge of a quantum spin Hall system, electron wavepackets of the helical states can be photoexcited by pure…
Symmetry protected topological phases of 1D interacting fermions with spin-charge separation
Arianna Montorsi, Fabrizio Dolcini, Rita Iotti +1
The low energy behavior of a huge variety of one-dimensional interacting spinful fermionic systems exhibits spin-charge separation, described in the continuum limit by two sine-Gor…
Electronic phase coherence versus dissipation in solid-state quantum devices: Two approximations are better than one
Rita Claudia Iotti, Fausto Rossi
In the microscopic modeling of new-generation electronic quantum nanodevices a variety of simulation strategies have been proposed and employed. Aim of this Letter is to point out…
Derivation of nonlinear single-particle equations via many-body Lindblad superoperators: A density-matrix approach
Roberto Rosati, Rita Claudia Iotti, Fabrizio Dolcini +1
A recently proposed Markov approach provides Lindblad-type scattering superoperators, which ensure the physical (positive-definite) character of the many-body density matrix. We ap…
Interplay between energy dissipation and reservoir-induced thermalization in nonequilibrium quantum nanodevices
Fabrizio Dolcini, Rita Claudia Iotti, Fausto Rossi
A solid state electronic nanodevice is an intrinsically open quantum system, exchanging both energy with the host material and carriers with connected reservoirs. Its out-of-equili…
