Stable and Metastable Kinetic Ferromagnetism on a Ring
Ilya Ivantsov, Hernan B. Xavier, Alvaro Ferraz +1
Performing an exact diagonalization of the effective spin problem, a ferromagnetic ground state of kinetic origin is shown to emerge in a system of strongly correlated electron…
Onset of ferromagnetism for strongly correlated electrons in one-dimensional chains
Hernan B Xavier, Evgenii Kochetov, Alvaro Ferraz
The existence of the Nagaoka ferromagnetism is examined in the context of the one-dimensional Hubbard model. We construct the exact quantum partition function to describ…
Comment on 'Coherent-state path integrals in the continuum'
Evgenii Kochetov
The authors of the recent paper [Phys. Rev. A 90, 032104 (2014)] claim to have established a time continuous formulation of path integration in the CS basis free from the mentioned…
Itinerant-localized model of strongly correlated electrons: Fermi-surface reconstruction
Ilya Ivantsov, Alvaro Ferraz, Evgenii Kochetov
A number of recent experiments have highlighted a remarkable transformation of a large cuprate Fermi surface into small pockets in the underdoped region signalling a breakdown of a…
