Excitonic Magnetism in Ruthenium Pyrochlores
Swetlana Swarup, Yang Yang, Natalia B. Perkins
Strong spin-orbit coupling in systems is expected to stabilize a nonmagnetic singlet ground state, yet many ruthenium pyrochlores exhibit robust long-range magnetic ord…
Collective magnetic Higgs excitation in a pyrochlore ruthenate
Dirk Wulferding, Junkyeong Kim, Mi Kyung Kim +13
The emergence of scalar Higgs-type amplitude modes in systems where symmetry is spontaneously broken has been a highly successful, paradigmatic description of phase transitions, wi…
Signatures of non-Loudon-Fleury Raman scattering in the Kitaev magnet -LiIrO
Yang Yang, Yiping Wang, Ioannis Rousochatzakis +4
We investigate the magnetic excitations of the hyperhoneycomb Kitaev magnet - by means of inelastic Raman scattering. The spectra exhibits a coexistence…
Shubnikov-de Haas Oscillations and Nontrivial Topological State in a New Weyl Semimetal Candidate SmAlSi
Longmeng Xu, Haoyu Niu, Yuming Bai +7
We perform the quantum magnetotransport measurements and first-principles calculations on high quality single crystals of SmAlSi, a new topological Weyl semimetal candidate. At low…
Non-Loudon-Fleury Raman scattering in spin-orbit coupled Mott insulators
Yang Yang, Mengqun Li, Ioannis Rousochatzakis +1
We revisit the theory of magnetic Raman scattering in Mott insulators with strong spin-orbit coupling, with a major focus on Kitaev materials. We show that Kitaev materials with bo…
Quantum-classical crossover in the spin-1/2 Heisenberg-Kitaev kagome magnet
Yang Yang, Natalia B. Perkins, Fulya Koç +2
The spin-1/2 Heisenberg kagome antiferromagnet is one of the paradigmatic playgrounds for frustrated quantum magnetism, with an extensive number of competing resonating valence bon…
