Spin-liquid-like spin dynamics in the frustrated antiferromagnet TbBO3

Through thermodynamic, muon-spin relaxation, and neutron scattering measurements down to 16 mK, this study reveals that the distorted triangular lattice antiferromagnet TbBO3 exhibits persistent spin-liquid-like dynamics driven by dominant 2D short-range correlations and the interplay of frustration and spin-orbit coupling, despite the absence of long-range magnetic order.

Versatile multi-q antiferromagnetic charge order in correlated vdW metals

Using low-temperature scanning tunneling microscopy, researchers discovered that the van der Waals metal CeTe3 hosts versatile, competing antiferromagnetic charge-ordered states (stripe and checkerboard) tunable by modest magnetic fields, revealing a rich, strongly correlated electronic landscape that extends beyond weak-coupling descriptions and offers a new platform for engineering tunable nanoscale quantum states.

Challenges in predicting positron annihilation lifetimes in lead halide perovskites: correlation functionals and polymorphism

This study demonstrates that the choice of electron-positron correlation functional, particularly the use of the non-local weighted density approximation (WDA), is critical for accurately predicting positron annihilation lifetimes in lead halide perovskites, revealing that previous discrepancies in theoretical predictions and experimental interpretations of cation vacancies stem from the sensitivity of these materials to the specific approximation used.
