Competing Antiferromagnetic and Spin-Glass Phases in a Hollandite Structure
Y. Crespo, A. Andreanov, N. Seriani
We introduce a simple lattice model with Ising spins to explain recent experimental results on spin freezing in a hollandite-type structure. We argue that geometrical frustration o…
Spatial correlations in finite samples revealed by Coulomb explosion
Ulf Saalmann, Alexey Mikaberidze, Jan M. Rost
We demonstrate that fast removal of many electrons uncovers initial correlations of atoms in a finite sample through a pronounced peak in the kinetic-energy spectrum of the explodi…
Anomalous Hall effect from frustration-tuned scalar chirality distribution in Pr2Ir2O7
Masafumi Udagawa, Roderich Moessner
We analyse the Ising Kondo lattice model on a pyrochlore structure in order to study the anomalous Hall effect due to non-coplanar magnetism. We focus on the frustration-induced sp…
Space-time velocity correlation function for random walks
V. Zaburdaev, S. Denisov, P. Hanggi
Space-time correlation functions constitute a useful instrument from the research toolkit of continuous-media and many-body physics. We adopt here this concept for single-particle…
Distant-Neighbor Hopping in Graphene and Haldane Models
Doru Sticlet, Frédéric Piéchon
Large Chern number phases in a Haldane model become possible if there is a multiplication of Dirac points in the underlying graphene model. This is realized by considering long-dis…
Sum rule violation in self-consistent hybridization expansions
Andreas Rüegg, Emanuel Gull, Gregory A. Fiete +1
We show that for multi-orbital quantum impurity models the non-crossing approximation and one-crossing approximation versions of the self-consistent hybridization expansions violat…
