Kondo breakdown is one of the most intriguing problems in strongly correlated electron systems, as it is rooted in many anomalous electron behaviors found in heavy-fermion materials. In Kondo lattice systems, Kondo breakdown can arise from either strong magnetic frustrations or critical fluctuations of collective modes. Here, we reveal a new type of Kondo breakdown with a fully different origin in interacting topological Kondo insulators. By employing numerically exact quantum Monte Carlo…

Topological Kondo insulators.
A topological classification of emergent band structures for Kondo insulators is developed and it is shown that these materials may host three-dimensional topological insulating phases.
Topological phase in 1D topological Kondo insulator: Z2 topological insulator, Haldane-like phase and Kondo breakdown
Abstract We have simulated a half-filled 1Dp-wave periodic Anderson model with numerically exact projector quantum Monte Carlo technique, and the system is indeed located in the Haldane-like state as
Observation of possible topological in-gap surface states in the Kondo insulator SmB6 by photoemission
By performing angle-resolved photoemission spectroscopy experiments, several dispersive states within the hybridization gap of SmB6 show negligible kz dependence, which indicates their surface origin, and photoemissions circular dichroism experiments suggest that the in-gap states possess chirality of the orbital angular momentum.
Quantum criticality and global phase diagram of magnetic heavy fermions
Quantum criticality describes the collective fluctuations of matter undergoing a second-order phase transition at zero temperature. It is being discussed in a number of strongly correlated electron
Kondo effect in real metals
Starting from the most general form of the Anderson hamiltonian, the behaviour of magnetic impurities in real metals is considered, taking into account the orbital structure of the local impurity
Robust Surface Hall Effect and Nonlocal Transport in SmB6: Indication for an Ideal Topological Insulator
A topological insulator (TI) is an unusual quantum state in which the insulating bulk is topologically distinct from vacuum, resulting in a unique metallic surface that is robust against
Locally critical quantum phase transitions in strongly correlated metals
The theoretical finding of a locally critical quantum phase transition in a model of heavy fermions is reported, and local criticality is proposed to be a phenomenon of general relevance to strongly correlated metals.
Orbital-Selective Mott Transitions: Heavy Fermions and Beyond
Quantum phase transitions in metals are often accompanied by violations of Fermi liquid behavior in the quantum critical regime. Particularly fascinating are transitions beyond the
Quantized electric multipole insulators
This work introduces a paradigm in which “nested” Wilson loops give rise to topological invariants that have been overlooked and opens a venue for the expansion of the classification of topological phases of matter.
Onset of antiferromagnetism in heavy-fermion metals
Evidence is found for an atomically local contribution to the magnetic correlations which develops at the critical gold concentration, corresponding to a magnetic ordering temperature of zero, which implies that a Fermi-liquid-destroying spin-localizing transition, unanticipated from the spin density wave description, coincides with the antiferromagnetic quantum critical point.
