Absence of a magnetic-field-induced metal-insulator transition in Kondo insulators.
We investigate whether or not Kondo insulators undergo a magnetic-field-induced metal-insulator transition in one dimension at half filling using both a density matrix formulation of the numerical renormalization group and bosonization. Contrary to expectations, the quasiparticle gap never vanishes at any field and no metalinsulator transition is found. We discuss generalizing our result to the...
متن کاملInsulator-to-metal transition in Kondo insulators under a strong magnetic field.
Magnetization curve and changes of the single-particle excitation spectra by magnetic field are calculated for the periodic Anderson model at half-filling in infinite spatial dimension by using the exact diagonalization method. It is found that the field-induced insulator-to-metal transition occurs at a critical field Hc, which is of the order of the single ion Kondo temperature. The transition...
متن کاملMagnetic field-induced ordering in SrDy2O4.
Heat capacity measurements were used to investigate the magnetic ordering processes in single-crystal samples of SrDy2O4 in a magnetic field applied along the [010] and [001] directions. In zero field this compound appears to be magnetically disordered down to at least 0.39 K. A magnetic field applied along the [010] direction induces a very sharp transition at 20 kOe, seen as a strong peak in ...
متن کاملSelf-consistent perturbational study of insulator-to-metal transition in Kondo insulators due to strong magnetic field
In order to study the effects of strong magnetic field on Kondo insulators, we calculate magnetization curves and single-particle excitation spectra of the periodic Anderson model at half-filling under finite magnetic field by using the self-consistent second-order perturbation theory combined with the local approximation which becomes exact in the limit of infinite spatial dimensions. Without ...
متن کاملKondo breakdown in topological Kondo insulators.
Motivated by the observation of light surface states in SmB6, we examine the effects of surface Kondo breakdown in topological Kondo insulators. We present both numerical and analytic results which show that the decoupling of the localized moments at the surface disturbs the compensation between light and heavy electrons and dopes the Dirac cone. Dispersion of these uncompensated surface states...
