报告摘要

Symmetry stands as a cornerstone in condensed matter physics. However, while symmetry analysis provides invaluable insights, it often falls short of providing precise numerical values. Herein lies the complementary role of Density Functional Theory (DFT) simulations. In this talk, I will present our recent research endeavors involving theoretical studies of novel phenomena in ferroelectric materials using the symmetry-adapted effective Hamiltonian method, geared towards designing strategies to control their collinear and non-collinear dipolar states. Specifically, the talk delves into two parts: (i) terahertz light-induced ferroelectric reversal and (ii) Screwing ferroelectricity. These studies unlock new functionalities and potential applications of ferroelectrics. Lastly, I will briefly introduce our state-of-the-art materials modeling approach.
