K $_{2}$ Co $_{2}$ (TeO $_{3}$ ) $_{3}$ $\cdot$ 2.5 H $_{2}$ O : A mineral-inspired pseudo-honeycomb cobalt dimer antiferromagnet

Austin M. Ferrenti, Maxime A. Siegler, Yiqing Hao +9

In recent years, magnetically-frustrated triangular and honeycomb lattice cobaltates have seen extensive study in the pursuit of a quantum spin liquid (QSL) state in a real materia…

Magnetization Plateaus in the Spin-Orbit Coupled Bilayer Triangular Lattice Antiferromagnet Rb2Co2(SeO3)3

Shengzhi Zhang, Gabriel Silva Freitas, Vivien S. Zapf +8

Geometric frustration among competing spin exchanges can give rise to novel quantum phases by enhancing fluctuations that drive magnetic systems beyond the classical regime. We inv…

Phase Diagram and Spectroscopic Signatures of a Supersolid in Quantum Ising Magnet K $_{2}$ Co(SeO $_{3}$ ) $_{2}$

Tong Chen, Alireza Ghasemi, Junyi Zhang +17

A supersolid is a quantum-entangled state of matter exhibiting the dual characteristics of superfluidity and solidity. Theory predicts that hard-core bosons with repulsive interact…

Quasi-two-dimensional Antiferromagnetic Spin Fluctuations in the Spin-triplet Superconductor Candidate CeRh $_{2}$ As $_{2}$

Tong Chen, Hasan Siddiquee, Zack Rehfuss +10

The tetragonal heavy-fermion superconductor CeRh $_{2}$ As $_{2}$ ( $T_{c} = 0.3$ K) exhibits an exceptionally high critical field of 14 T for $B ∥ c$ . It under…
