Dynamical scaling near the pseudogap quantum critical point of the two-dimensional Hubbard model
Mathias Pelz, Gabriel Kotliar, Jan von Delft +1
We study dynamical scaling in the quantum-critical fan of the pseudogap-metal to Fermi-liquid transition of the two-dimensional Hubbard model. Using a four-patch dynamical cluster…
Quantum criticality in the two-dimensional Hubbard model
Mathias Pelz, Gabriel Kotliar, Jan von Delft +1
We study the normal-state, doping-driven phase diagram of the square-lattice Hubbard model using the dynamical cluster approximation combined with the numerical renormalization gro…
First-Principles Effective Mass in the Three-Dimensional Uniform Electron Gas
Pengcheng Hou, Daniel Cerkoney, Zhiyi Li +6
The quasiparticle effective mass of the three-dimensional uniform electron gas (UEG) is a fundamental Fermi-liquid parameter whose value and density dependence have remained…
Unifying Variational and Dynamical Quantum Embedding: From Ghost Gutzwiller Approximation to Dynamical Mean-Field Theory
Samuele Giuli, Tsung-Han Lee, Yong-Xin Yao +4
Dynamical and variational frameworks have long been viewed as distinct paradigms. In particular, in quantum embedding (QE) frameworks, dynamical mean-field theory (DMFT) captures n…
Pseudogapped Fermi liquids from emergent quasiparticles
Andreas Gleis, Gabriel Kotliar
We propose an interacting model that is exactly solvable in any spatial dimension and gives rise to a Fermi liquid (FL) featuring a pseudogapped (PG) single-particle spectral funct…
Emergent low-energy bound states in the two-orbital Hubbard model
Y. Nunez-Fernandez, G. Kotliar, K. Hallberg
A repulsive Coulomb interaction between electrons in different orbitals in correlated materials can give rise to bound quasiparticle states. We study the non-hybridized two-orbital…
