Relativistic Effects in the Electron-Phonon Coupling to Odd-Parity Modes in KTaO3

Explore relativistic effects in electron-phonon coupling to odd-parity modes in KTaO3 through this 41-minute conference talk by Maria Gastiasoro from DIPC. Delve into the quantum mechanical interactions between electrons and phonons in potassium tantalate (KTaO3), with particular focus on how relativistic effects influence coupling to odd-parity vibrational modes. Examine the theoretical framework and computational approaches used to understand these complex many-body interactions in this quantum material. Learn about the implications of spin-orbit coupling and other relativistic corrections on the electronic and phononic properties of KTaO3, a material of significant interest in quantum materials research. Gain insights into advanced condensed matter physics concepts including electron-phonon interactions, symmetry considerations in crystalline materials, and the role of relativistic effects in determining material properties. This presentation was delivered as part of the Workshop on Frontiers in Quantum Materials, providing cutting-edge research perspectives on quantum materials and their fundamental physics.
