Listen! It's a phase transition. The sound of a shape-memory alloy

Carlo Andrea Rozzi, Annamaria Lisotti, Guido Goldoni +1

Shape-memory alloys exhibit a solid-to-solid phase transition that involves a temperature-driven rearrangement of their crystal structure and is responsible for their remarkable pr…

Density-functional approach to the band gaps of finite and periodic two-dimensional systems

Alberto Guandalini, Alice Ruini, Esa Räsänen +2

We present an approach based on density-functional theory for the calculation of fundamental gaps of both finite and periodic two-dimensional (2D) electronic systems. The computati…

Understanding real-time time-dependent density-functional theory simulations of ultrafast laser-induced dynamics in organic molecules

Jannis Krumland, Ana M. Valencia, Stefano Pittalis +2

Real-time time-dependent density functional theory, in conjunction with the Ehrenfest molecular dynamics scheme, is becoming a popular methodology to investigate ultrafast phenomen…

Bonds, lone pairs, and shells probed by means of on-top dynamical correlations

Stefano Pittalis, Daniele Varsano, Alain Delgado +1

The Electron Localization Function (ELF) by Becke and Edgecombe [J. Chem. Phys. {\bf 92}, 5397 (1990)] is routinely adopted as a descriptor of atomic shells and covalent bonds. Sin…

Same-spin dynamical correlation effects on the electron localization

Stefano Pittalis, Alain Delgado, Carlo Andrea Rozzi

The Electron Localization Function (ELF) -- as proposed originally by Becke and Edgecombe -- has been widely adopted as a descriptor of atomic shells and covalent bonds. The ELF ta…

Modeling solvation effects in real-space and real-time within Density Functional Approaches

Alain Delgado, Stefano Corni, Stefano Pittalis +1

The Polarizable Continuum Model (PCM) can be used in conjunction with Density Functional Theory (DFT) and its time-dependent extension (TDDFT) to simulate the electronic and optica…
