Anisotropic Kitaev Spin Glass in Li $_{2}$ Ru $_{x}$ Ir $_{1 - x}$ O $_{3}$

Mayia A. Vranas, Alejandro Ruiz, Vikram Nagarajan +8

Kitaev iridates have emerged as an important class of spin-orbit-entangled quantum materials in which bond-directional exchange interactions generate strong magnetic frustration an…

Spin-carrier coupling induced ferromagnetism and giant resistivity peak in EuCd $_{2}$ P $_{2}$

Veronika Sunko, Yue Sun, Mayia Vranas +14

EuCd $_{2}$ P $_{2}$ is notable for its unconventional transport: upon cooling the metallic resistivity changes slope and begins to increase, ultimately 100-fold, before returning to its…

Stabilization of three-dimensional charge order through interplanar orbital hybridization in Pr $_{x}$ Y $_{1 - x}$ Ba $_{2}$ Cu $_{3}$ O $_{6 + δ}$

Alejandro Ruiz, Brandon Gunn, Yi Lu +13

The shape of 3 $d$ -orbitals often governs the electronic and magnetic properties of correlated transition metal oxides. In the superconducting cuprates, the planar confinement of th…

Signatures of non-Loudon-Fleury Raman scattering in the Kitaev magnet $β$ -Li $_{2}$ IrO $_{3}$

Yang Yang, Yiping Wang, Ioannis Rousochatzakis +4

We investigate the magnetic excitations of the hyperhoneycomb Kitaev magnet $β$ - $Li_{2} IrO_{3}$ by means of inelastic Raman scattering. The spectra exhibits a coexistence…

Magnon-spinon dichotomy in the Kitaev hyperhoneycomb $β$ -Li $_{2}$ IrO $_{3}$

Alejandro Ruiz, Nicholas P. Breznay, Mengqun Li +16

The family of edge-sharing tri-coordinated iridates and ruthenates has emerged in recent years as a major platform for Kitaev spin liquid physics, where spins fractionalize into em…

Hidden spin-orbital order in the Kitaev hyperhoneycomb $β$ -Li $_{2}$ IrO $_{3}$

Alejandro Ruiz, Vikram Nagarajan, Mayia Vranas +8

We report the existence of a phase transition at high temperature in the 3D Kitaev candidate material, $β$ -Li $_{2}$ IrO $_{3}$ . We show that the transition is bulk, intrinsic and orders…

Evolution of charge order topology across a magnetic phase transition in cuprate superconductors

Mingu Kang, Jonathan Pelliciari, Alex Frano +17

Charge order is now accepted as an integral constituent of cuprate high-temperature superconductors, one that is intimately related to other instabilities in the phase diagram incl…

Persistent low-energy phonon broadening near the charge order $q$ -vector in bilayer cuprate Bi $_{2}$ Sr $_{2}$ CaCu $_{2}$ O $_{8 + δ}$

Yu He, Shan Wu, Yu Song +23

We report a persistent low-energy phonon broadening around $q_{B} \sim 0.28$ r.l.u. along the Cu-O bond direction in the high- $T_{c}$ cuprate Bi $_{2}$ Sr $_{2}$ CaCu $_{2}$ O $_{8 + δ}$ (Bi-2212).…

Field-induced intertwined orders in 3D Mott-Kitaev honeycomb $β$ -Li2IrO3

Alejandro Ruiz, Alex Frano, Nicholas P. Breznay +7

Honeycomb iridates are thought to have strongly spin-anisotropic exchange interactions that could lead to an extraordinary state of matter known as the Kitaev quantum spin liquid.…

Resonant x-ray scattering reveals possible disappearance of magnetic order under hydrostatic pressure in the Kitaev candidate $γ$ -Li $_{2}$ IrO $_{3}$

Nicholas P. Breznay, Alejandro Ruiz, Alex Frano +4

Honeycomb iridates such as $γ$ -Li $_{2}$ IrO $_{3}$ are argued to realize Kitaev spin-anisotropic magnetic exchange, along with Heisenberg and possibly other couplings. While systems with…

Photoexcited states of the harmonic honeycomb iridate γ-Li $_{2}$ IrO $_{3}$

J. P. Hinton, S. Patankar, E. Thewalt +8

We report equilibrium and nonequilibrium optical measurements on the recently synthesized "harmonic" honeycomb iridate γ-Li $_{2}$ IrO $_{3}$ (LIO), as well as the layered honeycomb irida…
