Spin dynamics in 2D materials
Objectives
Understand the time scaling of diffusion, explore the correlation between material dimension with such power law in time
Control the spin diffusion in the 2D material with such Hamiltonian engineering
Figure out the necessary decoupling to retrieve the coherent spin diffusion
