One-to-one quantum simulation of a frustrated magnet with 256 qubits

Lucas Leclerc, Sergi JuliÃ -FarrÃ©, Gabriel Silva Freitas +33

Analog quantum simulators offer a powerful microscopic probe of quantum many-body systems, yet have largely been benchmarked against model Hamiltonians rather than real materials.…

Field-Induced Selective Spin Gap Closure and Quantum Criticality in BaNd $_{2}$ ZnS $_{5}$

Sangyun Lee, A. J. Woods, B. Billingsley +11

We report thermodynamic evidence for field-induced mode-selective quantum criticality in the layered rare-earth magnet BaNd2ZnS5 (BNZS). Below the Neel temperature TN = 2.9 K, spin…

Spectrum and low-temperature bulk properties of triangular quantum spin liquid candidate NaYbSe $_{2}$

A. O. Scheie, Minseong Lee, Kevin Wang +18

We report neutron scattering, pressure-dependent AC calorimetry, and AC magnetic susceptibility measurements of triangular lattice NaYbSe $_{2}$ . We observe a continuum of scattering,…

Random singlet physics in exchange disordered 2D triangular YbCu $_{1.14}$ Se $_{2}$

Caitlin S. T. Kengle, Sean M. Thomas, Roman Movshovich +5

Quantum spin liquid (QSL) phases exist in theory, but real candidate QSL materials are often extraordinarily sensitive to structural defects which disrupt the ground state. Here, w…

Novel bipartite entanglement in the quantum dimer magnet Yb $_{2}$ Be $_{2}$ SiO $_{7}$

A. Brassington, Q. Ma, G. Duan +14

The quantum dimer magnet, with antiferromagnetic intradimer and interdimer Heisenberg exchange between spin-1/2 moments, is known to host an up/down - down/up singlet ground state…

Possible quantum spin liquid state of CeTa $_{7}$ O $_{19}$

N. Li, A. Rutherford, Y. Y. Wang +13

CeTa $_{7}$ O $_{19}$ is a recently found two-dimensional triangular lattice antiferromagnet without showing magnetic order. We grew high-quality CeTa $_{7}$ O $_{19}$ single crystals and st…
