A Microscopic View on the Mott transition in Chromium-doped V2O3
S. Lupi, L. Baldassarre, B. Mansart +18
V2O3 is the prototype system for the Mott transition, one of the most fundamental phenomena of electronic correlation. Temperature, doping or pressure induce a metal to insulator t…
Jahn-Teller distortions and the magnetic order in the perovskite manganites
Krzysztof Rościszewski, Andrzej M. Oleś
We introduce an effective model for electrons to describe three-dimensional perovskite (LaSrMnO and LaCaMnO) manganites and study the magn…
CdV2O4: A rare example of a collinear multiferroic spinel
G. Giovannetti, A. Stroppa, S. Picozzi +11
By studying the dielectric properties of the geometrically frustrated spinel CdV2O4, we observe ferroelectricity developing at the transition into the collinear antiferromagnetic g…
Fourier transformation and response functions
O. Gunnarsson, G. Sangiovanni, A. Valli +1
We improve on Fourier transforms (FT) between imaginary time and imaginary frequency used in certain quantum cluster approaches using the Hirsch-Fye method. The asymptoti…
Hidden dimer order in the quantum compass model
Wojciech Brzezicki, Andrzej M. Oleś
We introduce an exact spin transformation that maps frustrated Z_{i,j}Z_{i,j+1} and X_{i,j}X_{i+1,j} spin interactions along the rows and columns of the quantum compass model (QCM)…
Quantum phase transition between antiferromagnetic and charge order in the Hubbard-Holstein model
Johannes Bauer, Alex C. Hewson
We explore the quantum phase transitions between two ordered states in the infinite dimensional Hubbard-Holstein model at half filling. Our study is based on the dynamical mean fie…
