We report the results of extensive dynamical cluster approximation calculations, based on a quantum Monte Carlo solver, for the two-dimensional Kondo lattice model. Our particular cluster implementation renders possible the simulation of spontaneous antiferromagnetic symmetry breaking. By explicitly computing the single-particle spectral function both in the paramagnetic and antiferromagnetic phases, we follow the evolution of the Fermi surface across this magnetic transition. The results… Expand
Visualizing heavy fermions emerging in a quantum critical Kondo lattice
TLDR
It is demonstrated that proximity to a quantum critical point results in critical damping of the emergent heavy excitation of the Kondo lattice system. Expand
Toward a new microscopic framework for Kondo lattice materials.
TLDR
A new microscopic framework is developed that incorporates the basic concepts that emerge from a phenomenological description of the key experimental findings of the heavy electrons in Kondo lattice materials. Expand
Photo-emission signatures of coherence breakdown in Kondo alloys: dynamical mean-field theory approach
We study the Kondo alloy model on a square lattice using dynamical mean-field theory for Kondo substitution and disorder effects, together with static mean-field approximations. We computed andExpand
Zooming in on heavy fermions in Kondo lattice models
Resolving the heavy fermion band in the conduction electron momentum resolved spectral function of the Kondo lattice model is challenging since, in the weak coupling limit, its spectral weight isExpand
