ERC Advanced Grant

Discovering light induced phases by first principles materials design

PI: Matteo Calandra

Starting date : October 2022

The goal of the ERC DELIGHT is to develop a theoretical strategy to predict and discover photoinduced phases in materials. It aims at answering some of the following questions. Which systems undergo light induced phase transitions ? Can we use light pulses to enhance or tune charge density wave, ferroelectric and magnetic critical temperatures, to generate new topological phases or to optimize the properties of thermoelectric materials ? Can we develop an inverse design strategy, namely given a target property, determine which material will have to be photoexcited and at which fluence to obtain it ?
