Despite the exciting implications of Kitaev spin Hamiltonian, finding and confirming quantum spin-liquid state have proven incredibly difficult. Recently, applicability model has been expanded through development a microscopic description spin-1 interaction. Here we explore candidate honeycomb system, ${\mathrm{KNiAsO}}_{4}$, which meets many proposed criteria to generate such an Bulk measurements reveal antiferromagnetic transition at $\ensuremath{\sim}19$ K is generally robust applied...
Time reversal symmetry breaking Weyl semimetals are unique among materials in allowing the minimal number of points, thus offering clearest signatures associated physics. Here we present neutron diffraction, density-functional theory, and transport measurement results which indicate that ${\mathrm{EuCd}}_{2}{\mathrm{As}}_{2}$, under ambient field, strain, pressure, is such a material with single pair points. Our work reveals magnetic structure (magnetic space group...
Entanglement plays a pivotal role in numerous quantum applications, and as technology progresses, entanglement systems continue to expand. However, quantifying is complex problem, particularly for multipartite states. The currently available measures suffer from high computational complexity, unknown entangled states, complete information about the state often necessary, further complicating calculations. In this paper, we train neural networks quantify using input features based on squared...
Recently $\mathrm{Eu}{\mathrm{Cd}}_{2}{\mathrm{As}}_{2}$ was predicted to be a magnetic Weyl semimetal with lone pair of nodes generated by $A$-type antiferromagnetism and protected rotational symmetry. However, it soon discovered that the actual structure broke symmetry internal pressure later suggested as route stabilize desired state. In this work we test prediction synthesizing series ${\mathrm{Eu}}_{1\ensuremath{-}x}{\mathrm{Ba}}_{x}{\mathrm{Cd}}_{2}{\mathrm{As}}_{2}$ single crystals...
Background Anxiety disorders are among the most prevalent mental health conditions globally, particularly affecting adolescents and young adults (10-24 years), causing substantial psychological social impairments. This study analyzed changes in incidence, prevalence, disability-adjusted life years (DALYs) of anxiety this age group from 1990 to 2021, emphasizing impact socioeconomic disparities COVID-19 pandemic, post-2019. Methods Utilizing Global Burden Disease(GBD) 2021 data 204 countries,...
The Heisenberg triangular lattice quantum spin liquid and the phase transitions to nearby magnetic orders have received much theoretical attention, but clear experimental manifestations of these states are rare. This work investigates a new spin-half Yb$^{3+}$ delafossite material, KYbSe$_2$, whose inelastic neutron scattering spectra reveal diffuse continuum with sharp lower bound. Applying entanglement witnesses data reveals significant multipartite spread between its neighbors, analysis...
We present a comprehensive series of magnetic and neutron scattering measurements the sawtooth chain compound, CsCo 2 (MoO 4 ) (OH). The properties (OH) can be easily manipulated by applied fields.
We report the high-pressure synthesis and a comprehensive study of NaCo 2 (SeO 3 ) (OH) sawtooth chain structure using bulk magnetic properties neutron scattering.
The ability to design crystal lattices with specific sublattice geometries has long been sought after especially in the context of harnessing magnetic frustration elicit emergent physics. One approach which seen some success recently is sublattices chemically through use nonmagnetic linker ligands as scaffolding for ions. Here we report properties one such family materials, transition metal ($\mathit{TM}$) selenite hydrates chemical formula...
Introduction: Coronavirus disease 2019 (COVID-19) has an extremely high infection rate. This study aimed to investigate emotional states and COVID-19 of medical workers during the self-management strategy COVID-19.
