Compact representation of strongly correlated Green's functions: the MOR+EC way to explore phase space
Norman Hogan, A. F. Kemper, Carlos Mejuto-Zaera
Repeated evaluation of the single-particle Green's function (GF) across parameter space is a recurring bottleneck in many-body methods, limiting the resolution at which phase bound…
Bath parameterization in multi-band cluster Dynamical Mean-Field Theory
Diego Florez-Ablan, Carlos Mejuto-Zaera, Massimo Capone
Accurate and reliable algorithms to solve complex impurity problems are instrumental to a routine use of quantum embedding methods for material discovery. In this context, we emplo…
Altermagnetism from interaction-driven itinerant magnetism
Samuele Giuli, Carlos Mejuto-Zaera, Massimo Capone
Altermagnetism, a new phase of collinear spin-order sharing similarities with antiferromagnets and ferromagnets, has introduced a new guiding principle for spintronic/thermoelectri…
Quasilocal entanglement across the Mott-Hubbard transition
Gabriele Bellomia, Carlos Mejuto-Zaera, Massimo Capone +1
The possibility to directly measure, in a cold-atom quantum simulator, the von Neumann entropy and mutual information between a site and its environment opens new perspectives on t…
Efficient computational screening of strongly correlated materials -- Multi-orbital phenomenology within the ghost Gutzwiller approximation
Carlos Mejuto-Zaera, Michele Fabrizio
The theoretical description of strongly correlated materials relies on the ability to simultaneously capture, on equal footing, the different competing energy scales. Unfortunately…
Efficient hybridization fitting for dynamical mean-field theory via semi-definite relaxation
Carlos Mejuto-Zaera, Leonardo Zepeda-Núñez, Michael Lindsey +3
We introduce a nested optimization procedure using semi-definite relaxation for the fitting step in Hamiltonian-based cluster dynamical mean-field theory (DMFT) methodologies. We s…
