Quantum estimation and remote charge sensing with a hole-spin qubit in silicon
Gaia Forghieri, Andrea Secchi, Andrea Bertoni +2
Hole-spin qubits in semiconductors represent a mature platform for quantum technological applications. Here we consider their use as quantum sensors, and specifically for inferring…
Theory of multi-dimensional quantum capacitance and its application to spin and charge discrimination in quantum-dot arrays
Andrea Secchi, Filippo Troiani
Quantum states of a few-particle system capacitively coupled to a metal gate can be discriminated by measuring the quantum capacitance, which can be identified with the second deri…
Interacting holes in Si and Ge double quantum dots: from a multiband approach to an effective-spin picture
Andrea Secchi, Laura Bellentani, Andrea Bertoni +1
The states of two electrons in tunnel-coupled semiconductor quantum dots can be effectively described in terms of a two-spin Hamiltonian with an isotropic Heisenberg interaction. A…
Inter- and intra-band Coulomb interactions between holes in silicon nanostructures
Andrea Secchi, Laura Bellentani, Andrea Bertoni +1
We present a full derivation of the interaction Hamiltonian for holes in silicon within the six-band envelope-function scheme, which appropriately describes the valence band close…
Phonon-mediated superconductivity in strongly correlated electron systems: a Luttinger-Ward functional approach
Andrea Secchi, Marco Polini, Mikhail I. Katsnelson
We use a Luttinger-Ward functional approach to study the problem of phonon-mediated superconductivity in electron systems with strong electron-electron interactions (EEIs). Our der…
Adiabatic perturbation theory of nonequilibrium light-controlled superconductivity
Andrea Secchi, Marco Polini
Recent experiments, in which Terahertz (THz) light has been used to induce nonequilibrium superconducting states, have raised a number of intriguing fundamental questions. Theoreti…
