Formation of a Topological Monopole Lattice and its Dynamics in Three-dimensional Chiral Magnets
Seong-Gyu Yang, Ye-Hua Liu, Jung Hoon Han
Topologically protected swirl of the magnetic texture known as the Skyrmion has become ubiqui- tous in both metallic and insulating chiral magnets. Meanwhile the existence of its t…
Entanglement and corner Hamiltonian spectra of integrable open spin chains
Panjin Kim, Hosho Katsura, Nandini Trivedi +1
Entanglement spectra (ES) for the critical SU(N) (2 <= N <= 4) spin chains and other integrable models of finite length are studied with the density matrix renormalization group me…
Featureless quantum insulator on the honeycomb lattice
Panjin Kim, Hyunyong Lee, Shenghan Jiang +5
We show how to construct fully symmetric, gapped states without topological order on a honey- comb lattice for S = 1/2 spins using the language of projected entangled pair states(P…
Doping effects on charge density instability in non-centrosymmetric PbxTaSe2
Azat Sharafeev, Raman Sankar, Alexander Glamazda +4
We report on the investigation of vibrational and electronic properties of the Pb doped dichalcogenide PbxTaSe2 using Raman scattering experiments. We observe a marked variation of…
Geometric tuning of charge and spin correlations in manganite superlattices
K. Rogdakis, Z. Viskadourakis, A. P. Petrovic +3
We report a modulation of the in-plane magnetotransport in artificial manganite superlattice (SL) [(NdMnO3)n /(SrMnO3)n /(LaMnO3)n]m by varying the layer thickness n while keeping…
Fermi surface reconstruction and multiple quantum phase transitions in the antiferromagnet CeRhIn
L. Jiao, Y. Chen, Y. Kohama +15
Conventional, thermally-driven continuous phase transitions are described by universal critical behaviour that is independent of the specific microscopic details of a material. How…
