Small Fermi surface in the one-dimensional Kondo lattice model
J. C. Xavier, E. Novais, E. Miranda
We study the one-dimensional Kondo lattice model through the density matrix renormalization group (DMRG). Our results for the spin correlation function indicate the presence of a s…
Emergent SU(N) symmetry in disordered SO(N) spin chains
V. L. Quito, Pedro L. S. Lopes, José A. Hoyos +1
Strongly disordered spin chains invariant under the SO(N) group are shown to display random-singlet phases with emergent SU(N) symmetry without fine tuning. The phases with emergen…
Mechanism for enhanced disordered screening in strongly correlated metals: local vs. nonlocal effects
E. C. Andrade, E. Miranda, V. Dobrosavljevic
We study the low temperature transport characteristics of a disordered metal in the presence of electron-electron interactions. We compare Hartree-Fock and dynamical mean field the…
Physical properties and magnetic structure of TbRhIn5 intermetallic compound
R. Lora-Serrano, C. Giles, E. Granado +6
In this work we report the physical properties of the new intermetallic compound TbRhIn5 investigated by means of temperature dependent magnetic susceptibility, electrical resistiv…
Localization effects and inelastic scattering in disordered heavy electrons
M. C. O. Aguiar, E. Miranda, V. Dobrosavljevic
We study ground state and finite temperature properties of disordered heavy fermion metals by using a generalization of dynamical mean field theory which incorporates Anderson loca…
Possible Realization of Odd Frequency Pairing in Heavy Fermion Compounds
P. Coleman, E. Miranda, A. Tsvelik
Using Majorana Fermions to represent spins we re-examine the Kondo Lattice model for heavy fermions. The simplest decoupling procedure provides a realization of odd frequency super…
