Coupling between ferroelectric distortions and excitonic properties in PbTiO
Pietro Pacchioni, Lorenzo Varrassi, Cesare Franchini
PbTiO is a ferroelectric perovskite semiconductor with favourable electronic and optical properties, making it suitable for a wide range of applications, including photo-cataly…
Metastable Multi-centered Polarons in BiVO
Seyeon Park, Yajing Zhang, Michele Reticcioli +2
Polarons, quasiparticles formed through interactions between lattice and charge carriers (electrons and holes), strongly influence the electronic and optical properties of function…
Temperature dependent ferroelectricity in strained KTaO3 with machine learned force field
Yu Zhu, Luigi Ranalli, Taikang Chen +2
Ferroelectric materials are a class of dielectrics that exhibit spontaneous polarization which can be reversed under an external electric field. The emergence of ferroelectric orde…
AMaRaNTA: Automated First-Principles Exchange Parameters In 2D Magnets
Federico Orlando, Andrea Droghetti, Lorenzo Varrassi +7
Two-dimensional (2D) magnets host a wide range of exotic magnetic textures, whose low-energy excitations and finite-temperature properties are typically described by effective spin…
Total Variation-Based Image Decomposition and Denoising for Microscopy Images
Marco Corrias, Giada Franceschi, Michele Riva +5
Experimentally acquired microscopy images are unavoidably affected by the presence of noise and other unwanted signals, which degrade their quality and might hide relevant features…
Automatic determination of quasicrystalline patterns from microscopy images
Tano Kim Kender, Marco Corrias, Cesare Franchini
Quasicrystals are aperiodically ordered solids that exhibit long-range order without translational periodicity, bridging the gap between crystalline and amorphous materials. Due to…
Coupling between small polarons and ferroelectricity in BaTiO3
Darin Joseph, Cesare Franchini
In this study, we investigate the formation of electron and hole small polarons in the prototypical ferroelectric material BaTiO3, with a focus on their interaction with ferroelect…
