Metallic ferromagnetism in the systems with strongly correlated electrons [PDF]

open access: yes, 2005
The present paper considers the ground state ferromagnetic ordering in narrow-band models with strongly correlated electrons, in particular, in a single-band generalized Hubbard model with correlated hopping and interatomic exchange interaction, as well ...

Variational Studies of Exotic Bose Liquid, Spin Liquid, and Magnetic Phases [PDF]

open access: yes, 2011
The strong interest in strongly correlated systems in condensed matter physics has continued unabated for the past few decades. In recent years, the number of novel, exotic quantum phases found in theoretical studies has seen a phenomenal rise.

Formation of charge and spin ordering in strongly correlated electron systems [PDF]

open access: yes, 2011
In this review we present results of our theoretical study of charge and spin ordering in strongly correlated electron systems obtained within various generalizations of the Falicov-Kimball model.

Time-dependent density-functional theory for strongly correlated electrons [PDF]

open access: yes, 2019
One of the most used methods in condensed matter theory and quantum chemistry for the description of matter properties is Time-dependent density-functional theory (TDDFT), an alternative formalism to wave function methods which uses the time-dependent ...

Numerical Analysis of Strongly Correlated Electrons [PDF]

open access: yes, 2023
Understanding the behavior of electrons in materials due to the presence of strong correlations between electrons is still a significant challenge in condensed matter physics.

Charge frustration and quantum criticality for strongly correlated fermions [PDF]

open access: yes, 2008
We study a model of strongly correlated electrons on the square lattice which exhibits charge frustration and quantum critical behavior. The potential is tuned to make the interactions supersymmetric.

Resonant tunneling driven metal-insulator transition in double quantum-well structures of strongly correlated oxide [PDF]

open access: yes, 2021
International audienceAbstract The metal-insulator transition (MIT), a fascinating phenomenon occurring in some strongly correlated materials, is of central interest in modern condensed-matter physics.

Strongly correlated electrons in solids [PDF]

open access: yes, 2008
In this review, phenomena and ideas connected with strongly interacting electrons in condensed matter systems will be outlined. A simple picture which regards electrons as basically a free gas of quantum particles is the basis of our understanding of all

Bloch-Zener oscillations of strongly correlated electrons [PDF]

open access: yes, 2012
It is well known that an electron in a single-band tight-binding lattice coherently driven by an external dc electric field undergoes Bloch oscillations.

Many-body dynamic localization of strongly correlated electrons in ac-driven Hubbard lattices [PDF]

open access: yes, 2012
In the framework of the Hubbard model, it is shown that approximate dynamic localization for strongly correlated electrons hopping on a one-dimensional lattice and driven by a high-frequency sinusoidal field can be realized provided that periodic π phase
