Nearly-free electrons in a 5d delafossite oxide metal
Pallavi Kushwaha, Veronika Sunko, P. J. W. Moll +11
Understanding the role of electron correlations in strong spin-orbit transition-metal oxides is key to the realisation of numerous exotic phases including spin-orbit assisted Mott…
Sudden expansion and domain-wall melting of strongly interacting bosons in two-dimensional optical lattices and on multileg ladders
Johannes Hauschild, Frank Pollmann, Fabian Heidrich-Meisner
We numerically investigate the expansion of clouds of hard-core bosons in the two-dimensional square lattice using a matrix-product-state based method. This nonequilibrium set-up i…
Self-energy enhancements in doped Mott insulators
J. Merino, O. Gunnarsson, G. Kotliar
We analyze enhancements in the magnitude of the self-energy for electrons far away from the Fermi surface in doped Mott insulators using the dynamical cluster approximation to the…
Interfacial roughness and proximity effects in superconductor/ferromagnet CuNi/Nb heterostructures

We report an investigation of the structural and electronic properties of hybrid superconductor/ferromagnet (S/F) bilayers of composition Nb/CuNi prepared by magnetro…
A Rényi entropy perspective on topological order in classical toric code models
Johannes Helmes, Jean-Marie Stéphan, Simon Trebst
Concepts of information theory are increasingly used to characterize collective phenomena in condensed matter systems, such as the use of entanglement entropies to identify emergen…
Hour-glass magnetic excitations induced by nanoscopic phase separation in cobalt oxides LaSrCoO
Y. Drees, Z. W. Li, A. Ricci +10
The magnetic excitations in the cuprate superconductors might be essential for an understanding of high-temperature superconductivity. In these cuprate superconductors the magnetic…
Thermodynamics of anisotropic triangular magnets with ferro- and antiferromagnetic exchange
Burkhard Schmidt, Peter Thalmeier
We investigate thermodynamic properties like specific heat and susceptibility in anisotropic - triangular quantum spin systems (). As a universal tool…
Single-ion anisotropy and magnetic field response in spin ice materials HoTiO and DyTiO
Bruno Tomasello, Claudio Castelnovo, Roderich Moessner +1
Motivated by its role as a central pillar of current theories of dynamics of spin ice in and out of equilibrium, we study the single-ion dynamics of the magnetic rare earth ions in…
Ground state magnetic response of two coupled dodecahedra
N. P. Konstantinidis
The antiferromagnetic Heisenberg model on the dodecahedron possesses a number of ground state magnetization discontinuities in a field at the classical and quantum level, even thou…
Emergent Coulombic criticality and Kibble-Zurek scaling in a topological magnet
James Hamp, Anushya Chandran, Roderich Moessner +1
When a classical system is driven through a continuous phase transition, its nonequilibrium response is universal and exhibits Kibble-Zurek scaling. We explore this dynamical scali…
Continuum limit of lattice models with Laughlin-like ground states containing quasiholes
Ivan D. Rodriguez, Anne E. B. Nielsen
There has been a significant interest in the last years in finding fractional quantum Hall physics in lattice models, but it is not always clear how these models connect to the cor…
Exact parent Hamiltonians of bosonic and fermionic Moore-Read states on lattices and local models
Ivan Glasser, J. Ignacio Cirac, Germán Sierra +1
We introduce a family of strongly-correlated spin wave functions on arbitrary spin-1/2 and spin-1 lattices in one and two dimensions. These states are lattice analogues of Moore-Re…
