題目：Engineering Quantum Materials with the Cavity Vacuum: A First-Principles QEDFT Perspective

講者：陸意德 助理教授

服務單位：國立陽明交通大學 電子物理系

地點：本校科學三館1樓 SC157

摘要：

Even without external illumination, the vacuum fluctuations of an optical cavity can reshape the ground state of a solid, offering a new route to controlling quantum materials. In this talk, I will present a first-principles framework based on quantum-electrodynamical density functional theory (QEDFT) that captures this effect in periodic systems. Starting from the Pauli–Fierz Hamiltonian in the long-wavelength limit, we incorporate electron–photon correlations into the Kohn–Sham scheme and extend density-functional perturbation theory to include photon-mediated lattice dynamics. I will show that the cavity vacuum can alter materials properties such as tune semiconductor band gaps, modify superconducting critical temperatures, and induce topological phases. These results establish QEDFT as a predictive tool for designing cavity quantum materials.
