The phase diagram of the anisotropic spin-2 XXZ model: an infinite system DMRG study
Jonas A. Kjäll, Michael P. Zaletel, Roger S. K. Mong +2
We study the ground state phase diagram of the quantum spin-2 XXZ chain in the presence of on-site anisotropy using a matrix-product state based infinite system density-matrix-reno…
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…
Phase transitions in the frustrated Ising model on the square lattice
Songbo Jin, Arnab Sen, Wenan Guo +1
We consider the thermal phase transition from a paramagnetic to stripe-antiferromagnetic phase in the frustrated two-dimensional square-lattice Ising model with competing interacti…
Topological Resonances in Scattering on Networks (Graphs)
Sven Gnutzmann, Holger Schanz, Uzy Smilansky
We report on a hitherto unnoticed type of resonances occurring in scattering from networks (quantum graphs) which are due to the complex connectivity of the graph - its topology. W…
First-principles study of the structural stability of Mn3Z (Z=Ga, Sn and Ge) Heusler compounds
Delin Zhang, Binghai Yan, Shu-Chun Wu +4
We investigate the structural stability and magnetic properties of cubic, tetragonal and hexagonal phases of Mn3Z (Z=Ga, Sn and Ge) Heusler compounds using first-principles density…
