Band-filling effects on the Kondo-lattice properties

B. Coqblin, C. Lacroix, M. A. Gusmão +1

We present theoretical results for a Kondo-lattice model with spin-1/2 localized moments, including both the intrasite Kondo coupling and an intersite antiferromagnetic exchange in…

Antiferromagnetism and single-particle properties in the two-dimensional half-filled Hubbard model: Slater vs Mott-Heisenberg

K. Borejsza, N. Dupuis

We study antiferromagnetism and single-particle properties in the two-dimensional half-filled Hubbard model at low temperature. Collective spin fluctuations are governed by a non-l…

Spin Glass and Ferromagnetism in Kondo lattices compounds

S. G. Magalhaes, A. A. Schmidt, Alba Theumann +1

The Kondo lattice model has been analyzed in the presence of a random inter-site interaction among localized spins with non zero mean Jo and standard deviation J. Following the sam…

Spectroscopic signatures of a bandwidth-controlled Mott transition at the surface of 1T-TaSe $_{2}$

L. Perfetti, A. Georges, S. Florens +5

High-resolution angle-resolved photoemission (ARPES) data show that a metal-insulator Mott transition occurs at the surface of the quasi-two dimensional compound TaSe $_{2}$ . The tran…

Competing phases in the high field phase diagram of (TMTSF) $_{2}$ ClO $_{4}$

S. Haddad, S. Charfi-Kaddour, C. Nickel +2

A model is presented for the high field phase diagram of (TMTSF) $_{2}$ ClO $_{4}$ , taking into account the anion ordering, which splits the Fermi surface in two bands. For strong enough…

Quantum impurity solvers using a slave rotor representation

Serge Florens, Antoine Georges

We introduce a representation of electron operators as a product of a spin-carry ing fermion and of a phase variable dual to the total charge (slave quantum rotor). Based on this r…
