Nontrivial entanglement passively mediated by a quenched magnetic impurity
Adelina A. Orlandini, Germán G. Blesio, Claudio J. Gazza +1
We investigate the entanglement properties of a Kondo system undergoing a transition to a state with a quenched magnetic impurity, using the density matrix renormalization group (D…
Anisotropy-driven topological quantum phase transition in magnetic impurities
Germán G. Blesio, Luis O. Manuel, Armando A. Aligia
A few years ago, a topological quantum phase transition (TQPT) has been found in Anderson and Kondo 2-channel spin-1 impurity models that include a hard-axis anisotropy term $DS_z^…
Influence of oxygen on electronic correlation and transport in iron in the outer Earth's core
German G. Blesio, Leonid V. Pourovskii, Markus Aichhorn +3
Knowing the transport properties of iron under realistic conditions present in the Earth's core is essential for the geophysical modeling of Earth's magnetic field generation. Besi…
Signatures of Hund Metal and finite-frequency nesting in SrRuO Revealed by Electronic Raman Scattering
Germán Blesio, Sophie Beck, Olivier Gingras +2
We investigate the electronic Raman scattering of SrRuO using a material-realistic dynamical mean-field theory approach. We identify the low-energy Fermi liquid behavior an…
Partially disordered Heisenberg antiferromagnet with short-range stripe correlations
G. G. Blesio, F. T. Lisandrini, M. G. Gonzalez
Zero-point quantum fluctuations of a Néel order can produce effective interactions between quasi-orphan spins weakly coupled to the lattice. On the distort…
Topological quantum phase transition in individual Fe Atoms on MoS/Au(111)
G. G. Blesio, A. A. Aligia
In a recent experiment [Trishin et al., Phys. Rev. Lett. 127, 236801 (2021)] a rich physics was observed for Fe atoms on MoS/Au(111), characterized by three different behaviors…
