Andreev spin qubits based on the helical edge states of magnetically doped two-dimensional topological insulators
Edoardo Latini, Fausto Rossi, Fabrizio Dolcini
We show that Andreev spin qubits can be realized in a Josephson junction based on the helical edge states of a two-dimensional topological insulator (quantum spin Hall system) prox…
An Information-Theoretic Bound on Thermodynamic Efficiency and the Generalized Carnot's Theorem
Anna Gabetti, Fabrizio Dolcini, Davide Girolami
We derive a bound on the efficiency of thermal engines that can be sharper than Carnot's limit. It is a function of statistical correlations between the engine internal state and H…
Enhanced Thermoelectricity in Nanowires with inhomogeneous Helical states
Zahra Aslani, Fabio Taddei, Fabrizio Dolcini +1
Semiconductor nanowires (NWs) with strong Rashba spin-orbit coupling (RSOC), when exposed to a suitably applied Zeeman field, exhibit one-dimensional helical channels with a spin o…
Correlation functions of the Kitaev model with a spatially modulated phase in the superconducting order parameter
Fabian G. Medina Cuy, Fabrizio Dolcini
The Kitaev chain model with a spatially modulated phase in the superconducting order parameter exhibits two types of topological transitions, namely a band topology transition betw…
