ComDMFT v.2.0: Fully Self-Consistent ab initio GW+EDMFT for the Electronic Structure of Correlated Quantum Materials
Byungkyun Kang, Patrick Semon, Corey Melnick +5
ComDMFT is a parallel computational package designed to study the electronic structure of correlated quantum materials from first principles. Our approach is based on the combinati…
Information-theoretic measures of superconductivity in a two-dimensional doped Mott insulator
C. Walsh, M. Charlebois, P. Sémon +2
A key open issue in condensed matter physics is how quantum and classical correlations emerge in an unconventional superconductor from the underlying normal state. We study this pr…
Oxygen hole content, charge-transfer gap, covalency, and cuprate superconductivity
N. Kowalski, S. S. Dash, D. Sénéchal +1
Experiments have shown that the families of cuprate superconductors that have the largest transition temperature at optimal doping also have the largest oxygen hole content at that…
Infinite-layer nickelates as Ni-eg Hund's metals
Byungkyun Kang, Corey Melnick, Patrick Semon +4
The recent and exciting discovery of superconductivity in the hole-doped infinite-layer nickelate Nd 1-δ Sr δ NiO 2 draws strong attention to correlated quantum materials. From a t…
Pseudogap, van Hove Singularity, Maximum in Entropy and Specific Heat for Hole-Doped Mott Insulators
A. Reymbaut, S. Bergeron, R. Garioud +4
The first indication of a pseudogap in cuprates came from a sudden decrease of NMR Knight shift at a doping-dependent temperature . Since then, experiments have found phase…
ComDMFT: a Massively Parallel Computer Package for the Electronic Structure of Correlated-Electron Systems
Sangkook Choi, Patrick Semon, Byungkyun Kang +2
ComDMFT is a massively parallel computational package to study the electronic structure of correlated-electron systems (CES). Our approach is a parameter-free method based on ab in…
Thermodynamic and information-theoretic description of the Mott transition in the two-dimensional Hubbard model
C. Walsh, P. Sémon, D. Poulin +2
At the Mott transition, electron-electron interaction changes a metal, in which electrons are itinerant, to an insulator, in which electrons are localized. This phenomenon is centr…
Entanglement entropy and mutual information across the Mott transition in the two-dimensional Hubbard model
C. Walsh, P. Sémon, D. Poulin +2
Entanglement and information are powerful lenses to probe phases transitions in many-body systems. Motivated by recent cold atom experiments, which are now able to measure the corr…
An organizing principle for two-dimensional strongly correlated superconductivity
L. Fratino, P. Sémon, G. Sordi +1
Superconductivity in the cuprates exhibits many unusual features. We study the two-dimensional Hubbard model with plaquette dynamical mean-field theory to address these unusual fea…
Benchmark of a modified Iterated Perturbation Theory approach on the 3d FCC lattice at strong coupling
Louis-Francois Arsenault, Patrick Semon, A. -M. S. Tremblay
The Dynamical Mean-Field theory (DMFT) approach to the Hubbard model requires a method to solve the problem of a quantum impurity in a bath of non-interacting electrons. Iterated P…
Strong coupling superconductivity, pseudogap and Mott transition
G. Sordi, P. Sémon, K. Haule +1
An intricate interplay between superconductivity, pseudogap and Mott transition, either bandwidth driven or doping driven, occurs in materials. Layered organic conductors and cupra…
Optimal doping and entropic origin of giant thermopower in doped Mott insulators
Louis-Francois Arsenault, B. Sriram Shastry, Patrick Semon +1
This paper has been withdrawn by the authors because the results were incorrect due to the use of an impurity solver that fails at large interaction strength and above half-filling…
