Back and forth from Fock space to Hilbert space: a guide for commuters
Andrea Beggi, Ilaria Siloi, Claudia Benedetti +4
Quantum states of systems made of many identical particles, e.g. those described by Fermi-Hubbard and Bose-Hubbard models, are conveniently depicted in the Fock space. However, in…
GPU-accelerated algorithms for many-particle continuous-time quantum walks
Enrico Piccinini, Claudia Benedetti, Ilaria Siloi +2
Many-particle continuous-time quantum walks (CTQWs) represent a resource for several tasks in quantum technology, including quantum search algorithms and universal quantum computat…
Noisy quantum walks of two indistinguishable interacting particles
Ilaria Siloi, Claudia Benedetti, Enrico Piccinini +4
We investigate the dynamics of continuous-time two-particle quantum walks on a one-dimensional noisy lattice. Depending on the initial condition, we show how the interplay between…
Nanoscale Phase Change Memory with Graphene Ribbon Electrodes
Ashkan Behnam, Feng Xiong, Andrea Cappelli +9
Phase change memory (PCM) devices are known to reduce in power consumption as the bit volume and contact area of their electrodes are scaled down. Here, we demonstrate two types of…
Hot-carrier trap-limited transport in switching chalcogenides
Enrico Piccinini, Andrea Cappelli, Fabrizio Buscemi +4
Chalcogenide materials have received great attention in the last decade owing to their application in new memory systems. Recently, phase-change memories have, in fact, reached the…
Conduction, diffusion and noise of electrons in amorphous chalcogenides at low electric fields
Fabrizio Buscemi, Enrico Piccinini, Rossella Brunetti +2
The low-field electron diffusion, noise, and the conduction in amorphous chalcogenides are investigated by means of a Monte Carlo implementation of a full three- dimensional variab…
Electronic, optical and thermal properties of the hexagonal and fcc Ge2Sb2Te5 chalcogenide from first-principle calculations
Thierry Tsafack, Enrico Piccinini, Bong-Sub Lee +2
We present a comprehensive computational study on the properties of face-centered cubic and hexagonal chalcogenide Ge2Sb2Te5. We calculate the electronic structure using density fu…
