Probing the Mott physics in kappa-(BEDT-TTF)(2)X salts via thermal expansion
(Iop Publishing Ltd, 2015-02-11)
In the field of interacting electron systems the Mott metal-to-insulator (MI) transition represents one of the pivotal issues. The role played by lattice degrees of freedom for the Mott MI transition and the Mott criticality ...

Critical Theory of Two-Dimensional Mott Transition: Integrability and Hilbert Space Mapping
(Scientific Research Publishing, 2015-04)
We reconsider the Mott transition in the context of a two-dimensional fermion model with density-density coupling. We exhibit a Hilbert space mapping between the original model and the Double Lattice Chern-Simons theory ...
Mott-Anderson metal-insulator transitions from entanglement
(2021-10-01)
A metal can be driven to an insulating phase through distinct mechanisms. A possible way is via the Coulomb interaction, which then defines the Mott metal-insulator transition (MIT). Another possibility is the MIT driven ...
Effective field theory and integrability in two-dimensional Mott transition
(2010)
Abstract: We study the Mott transition in a two-dimensional lattice spinless fermion model with nearest neighbors density-density interactions. By means of a two-dimensional Jordan-Wigner transformation, the model is mapped ...
Mott transition of fermionic mixtures with mass imbalance in optical lattices
(American Physical Society, 2012-01)
We investigate the effect of mass imbalance in binary Fermi mixtures loaded in optical lattices. Using dynamical mean-field theory, we study the transition from a fluid to a Mott insulator driven by the repulsive interactions. ...

Efeitos de localização de Anderson próximo à transição metal-isolante de Mott
(Universidade Federal de Minas GeraisUFMG, 2014-02-21)
The Coulomb repulsion between electrons strongly a ects the properties of a class of materials, which can go through a metal-insulator phase transition - the so called Mott transition, when this interaction energy becomes ...
Griffiths-like phase close to the Mott transition
(Amer Inst Physics, 2020-12-14)
We explore the coexistence region in the vicinity of the Mott critical end point employing a compressible cell spin- 1 / 2 Ising-like model. We analyze the case for the spin-liquid candidate kappa-(BEDT-TTF) 2Cu 2(CN) 3, ...
