Variational wavefunctions for Sachdev-Ye-Kitaev models
Arijit Haldar, Omid Tavakol, Thomas Scaffidi
Given a class of -local Hamiltonians, is it possible to find a simple variational state whose energy is a finite fraction of the ground state energy in the thermodynamic limit?…

Artificial electric field and electron hydrodynamics
Omid Tavakol, Yong Baek Kim
In the electron dynamics in quantum matter, the Berry curvature of the electronic wave function provides the artificial magnetic field (AMF) in momentum space, which leads to non-t…
