Thermodynamics of the Quantum Critical Point at Finite Doping in the 2D Hubbard Model: A Dynamical Cluster Approximation Study
K. Mikelsons, E. Khatami, D. Galanakis +3
We study the thermodynamics of the two-dimensional Hubbard model within the dynamical cluster approximation. We use continuous time quantum Monte Carlo as a cluster solver to avoid…

The relationship between Hirsch-Fye and weak coupling diagrammatic Quantum Monte Carlo methods
Karlis Mikelsons, Alexandru Macridin, Mark Jarrell
Two weak coupling Continuous Time Quantum Monte Carlo (CTQMC) methods are shown to be equivalent for Hubbard-like interactions. A relation between these CTQMC methods and the Hirsc…
