Accounting for Quantum Effects in Atomistic Spin Dynamics
Marco Berritta, Stefano Scali, Federico Cerisola +1
Atomistic spin dynamics (ASD) is a standard tool to model the magnetization dynamics of a variety of materials. The fundamental dynamical model underlying ASD is entirely classical…
Graph theory approach to exceptional points in wave scattering
Stefano Scali, Janet Anders, Simon A. R. Horsley
In this paper, we use graph theory to solve wave scattering problems in the discrete dipole approximation. As a key result of this work, in the presence of active scatterers, we pr…
Quantum-classical correspondence in spin-boson equilibrium states at arbitrary coupling
Federico Cerisola, Marco Berritta, Stefano Scali +3
The equilibrium properties of nanoscale systems can deviate significantly from standard thermodynamics due to their coupling to an environment. For the generalised -angled spin-…
Local master equations bypass the secular approximation
Stefano Scali, Janet Anders, Luis A. Correa
Master equations are a vital tool to model heat flow through nanoscale thermodynamic systems. Most practical devices are made up of interacting sub-system, and are often modelled u…
Entanglement distance for arbitrary -qudit hybrid systems
Denise Cocchiarella, Stefano Scali, Salvatore Ribisi +3
The achievement of quantum supremacy boosted the need for a robust medium of quantum information. In this task, higher-dimensional qudits show remarkable noise tolerance and enhanc…
Entanglement distance for an arbitrary state of M qubits
Denise Cocchiarella, Stefano Scali, Salvatore Ribisi +3
We propose a measure of entanglement that can be computed for any pure state of an -qubit system. The entanglement measure has the form of a distance that we derive from an adap…
Entanglement estimation in non-optimal qubit states
Stefano Scali, Roberto Franzosi
In the last years, a relationship has been established between the quantum Fisher information (QFI) and quantum entanglement. In the case of two-qubit systems, all pure entangled s…
