Emerging Magnetoelectric Responses in Quantum Materials

In this talk, I will discuss emerging magnetoelectric responses in quantum materials, such as materials with broken inversion or time reversal symmetry, and twisted atomic bilayers. I will emphasize on magnetoelectric responses which has a quantum origin, and their experimental signatures on optical experiments through concrete materials systems. Some fundamental questions related to magnetoelectric responses are; can mgnetoelectric coefficients be significantly larger than that observed in conventional chiral molecules, can magnetoelectic reponses be tunable, amplified magnetoelectric responses through electrical bias, among others.
