Observation of orbital moment in NiO

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 ...
Magnetic field induced lattice effects in a quasi-two-dimensional organic conductor close to the Mott metal-insulator transition
(Amer Physical Soc, 2012-08-21)
We present ultra-high-resolution dilatometric studies in magnetic fields on a quasi-two-dimensional organic conductor kappa-(D8-BEDT-TTF)(2)Cu[N(CN)(2)]Br, which is located close to the Mott metal-insulator (MI) transition. ...
Universality of liquid-gas Mott transitions at finite temperatures

Entanglement and the Mott insulator-superfluid phase transition in bosonic atom chains
(Iop Publishing LtdBristolInglaterra, 2010)
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, ...
Mott insulator and superfluid phases in bosonic superlattices
(2016-02-12)
We study the ground-state phase diagram of boson chains on a 2-period superlattice
using the density matrix renormalization group method. New insulators for commensurate
densities were found, diferentiated by the arrangement ...
Spin relaxation near the metal-insulator transition: Dominance of the Dresselhaus spin-orbit coupling
(American Physical Society, 2012-01)
We identify the Dresselhaus spin-orbit coupling as the source of the dominant spin-relaxation mechanism in the impurity band of a wide class of n-doped zinc blende semiconductors. The Dresselhaus hopping terms are derived ...
