DESCRIPTION:Speaker: Steve Winter\nhosted by Zhanybek Alpichshev\nAbstract:
  Quantum materials represent a broad class of systems whose experimental r
 esponse relies on uniquely quantum aspects such as entanglement\, Berry ph
 ases\, and electronic correlations. Modeling of such materials presents ch
 allenges related to a variety complex behaviours that manifest at differen
 t energy scales. In this field\, first-principles approaches often provide
  a vital bridge between experiments and theoretical models. In this talk\,
  I will introduce our numerical strategies for systematically building low
 -energy models with local charge\, spin\, and orbital degrees of freedom o
 f arbitrary complexity. I will discuss the insights that these methods hav
 e yielded for frustrated Co(II)-based magnetic insulators and layered vdW 
 materials\, in which spin-orbit coupling induces strongly anisotropic and 
 competing magnetic interactions. I will also discuss preliminary work on e
 xtending these methods to treat (i) spin-lattice coupling\, and (ii) dynam
 ical effective Hamiltonians for modeling non-linear responses in quantum m
 aterials\, and the breadth of opportunities for non-linear spectroscopy.
