DESCRIPTION:Nonlinear transport and optical phenomena\, such as charge and
  spin photogalvanic effects and high-harmonic generation\, are of signific
 ant interest in condensed matter physics due to their applications in phot
 odetection\, optospintronics\, and nanoscale imaging of quantum materials.
  Understanding low-frequency nonlinear photocurrents provides a means to p
 robe and leverage quantum geometry and many-body effects in crystalline ma
 terials. In this talk\, I will review both old and recent results in nonli
 near transport and optics in two-dimensional layered materials\, including
  many-body renormalization of nonlinear optical responses in graphene and 
 the nonlinear Hall effect.  I will particularly focus on nonlinear photo-t
 hermoelectric effects and magneto-transport in 2D Fermi liquids\, highligh
 ting their role in probing the long-lived dynamics of odd-parity Fermi liq
 uid modes in the hydrodynamic (tomographic) regime.
