"Nonlinear Phononics: A Dynamical Tuning Knob in Bilayer van der Waals Magnets"
Abstract: This dissertation focuses on using light to achieve ultrafast control of quantum materials, particularly through the nonlinear phononics mechanism. This allows for dynamical control of lattice geometry, symmetry and related quantum properties of materials. We used theoretical modeling combined with input from first principle calculation to demonstrate ultrafast controls of mag- netic exchange coupling, electronic topology, magnetic anisotropy, and magnon spectrum.
