Momentum polarization: an entanglement measure of topological spin and chiral central charge

Hong-Hao Tu, Yi Zhang, Xiao-Liang Qi

Topologically ordered states are quantum states of matter with topological ground state degeneracy and quasi-particles carrying fractional quantum numbers and fractional statistics…

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…

Nernst Effect as a Probe of Local Kondo Scattering in Heavy Fermions

Peijie Sun, Frank Steglich

A large, strongly temperature-dependent Nernst coefficient, $ν$ , is observed between $T$ = 2 K and 300 K for CeCu $_{2}$ Si $_{2}$ and Ce $_{0.8}$ La $_{0.2}$ Cu $_{2}$ Si $_{2}$ . The enhanced $ν(T)…

Depth profile of the ferromagnetic order in a YBa $_{2}$ Cu $_{3}$ O $_{7}$ / La $_{2/3}$ Ca $_{1/3}$ MnO $_{3}$ superlattice on a LSAT substrate: a polarized neutron reflectometry study

M. A. Uribe-Laverde, D. K. Satapathy, I. Marozau +10

Using polarized neutron reflectometry (PNR) we have investigated a YBa2Cu3O7(10nm)/La2/3Ca1/3MnO3(9nm)]10 (YBCO/LCMO) superlattice grown by pulsed laser deposition on a La0.3Sr0.7A…

Disorder by disorder and flat bands in the kagome transverse field Ising model

M. Powalski, K. Coester, R. Moessner +1

We study the transverse field Ising model on a kagome and a triangular lattice using high-order series expansions about the high-field limit. For the triangular lattice our results…

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…
