Dynamics and transport properties of Kondo insulators
Published 2003“…A many-body theory of paramagnetic Kondo insulators is described, focusing specifically on single-particle dynamics, scattering rates, d.c. transport and optical conductivities. …”

Dynamics and scaling in the periodic Anderson model
Published 2004“…Yet even for the paramagnetic metallic phase, a practicable many-body theory that can simultaneously handle all energy scales while respecting the dictates of Fermi liquid theory at low energies, and all interaction strengths from the strongly correlated Kondo lattice through to weak coupling, has remained quite elusive. …”

Point-defect optical transitions and thermal ionization energies from quantum Monte Carlo methods: Application to the F-center defect in MgO
Published 2013“…The use of an inherently many-body theory that directly treats electron correlation offers many improvements over the typically employed density functional theory Kohn-Sham description. …”

Duality between ( 2 + 1 ) d quantum critical points
Published 2021“…Recently there has been tremendous progress in formulating and understanding possible dualities of quantum many body theories in 2+1-spacetime dimensions. Of particular interest are dualities that describe conformally invariant quantum field theories in (2+1)d. …”
