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…
