Unveiling Hidden Orders: Magnetostriction as a Probe of Multipolar-Ordered States
Adarsh S. Patri, Akito Sakai, SungBin Lee +3
Broken symmetries in solids involving higher order multipolar degrees of freedom are historically referred to as "hidden orders" due to the formidable task of detecting them with c…
Non-local String Order Parameter in the Kitaev-Heisenberg Ladder
Andrei Catuneanu, Erik S. Sørensen, Hae-Young Kee
We study the spin- Kitaev-Heisenberg (KJ) model in a two-leg ladder. Without a Heisenberg interaction, the Kitaev phase in the ladder model has Majorana fermions with…
Local magnetism, magnetic order and spin freezing in the 'nonmetallic metal' FeCrAs
B. M. Huddart, M. T. Birch, F. L. Pratt +7
We present the results of x-ray scattering and muon-spin relaxation (SR) measurements on the iron-pnictide compound FeCrAs. Polarized non-resonant magnetic x-ray scattering…
Electric-field Control of Magnetism with Emergent Topological Hall Effect in SrRuO3 through Proton Evolution
Zhuolu Li, Shengchun Shen, Zijun Tian +16
Ionic substitution forms an essential pathway to manipulate the carrier density and crystalline symmetry of materials via ion-lattice-electron coupling, leading to a rich spectrum…
Topological d+s wave superconductors in a multi-orbital quadratic band touching system
GiBaik Sim, Archana Mishra, Moon Jip Park +3
Realization of topological superconductors is one of the most important goals in studies of topological phases in quantum materials. In this work, we theoretically propose a novel…
Multi-scale Quantum Criticality driven by Kondo-lattice Coupling in Pyrochlore Systems
Hanbit Oh, Sangjin Lee, Yong Baek Kim +1
Pyrochlore systems () with -site rare-earth local moments and -site conduction electrons offer excellent material platforms for the discovery of exotic…
