Antiferromagnetic Exchange, Hund's Coupling and the Origin of the Charge Gap in LaMnPO
D. E. McNally, J. W. Simonson, K. W. Post +12
We present inelastic neutron scattering and magnetization measurements of the antiferromagnetic insulator LaMnPO that are well described by a Heisenberg spin model. These measureme…
transition in cerium: magnetic form factor and dynamic magnetic susceptibility in dynamical mean-field theory
B. Chakrabarti, M. E. Pezzoli, G. Sordi +2
The nature of the elemental cerium phases, undergoing an isostructural volume collapse transition, cannot be understood using conventional solid state concepts. Using the combinati…
From antiferromagnetic insulator to correlated metal in pressurized and doped LaMnPO
J. W. Simonson, Z. P. Yin, M. Pezzoli +17
Widespread adoption of superconducting technologies requires the discovery of new materials with enhanced properties, especially higher superconducting transition temperatures T$_{…
Local suppression of the hidden order phase by impurities in URu2Si2
Maria E. Pezzoli, Matthias J. Graf, Kristjan Haule +2
We consider the effects of impurities on the enigmatic hidden order (HO) state of the heavy-fermion material URu2Si2. In particular, we focus on local effects of Rh impurities as a…
Neutron magnetic form factor in strongly correlated materials
Maria Elisabetta Pezzoli, Kristjan Haule, Gabriel Kotliar
We introduce a formalism to compute the neutron magnetic form factor Fm(q) within a first-principles Density Functional Theory (DFT) + Dynamical Mean Field Theory (DMFT). The appro…
Ground-state properties of the disordered Hubbard model in two dimensions
Maria Elisabetta Pezzoli, Federico Becca
We study the interplay between electron correlation and disorder in the two-dimensional Hubbard model at half-filling by means of a variational wave function that can interpolate b…
Local moments and magnetic order in the two-dimensional Anderson-Mott transition
Maria Elisabetta Pezzoli, Federico Becca, Michele Fabrizio +1
We study the role of electronic correlation in a disordered two-dimensional model by using a variational wave function that can interpolate between Anderson and Mott insulators. Wi…
