  • This study shows that the nodal loop topology in LaSbxTe2−x can be controlled by chemical substitution and electron doping. The reversible opening and closing of a gap larger than 400 meV in the nodal loop enables on-demand switching of topology.

  • The authors study the non-centrosymmetric achiral material InxTaS2 by angle-resolved photoemission spectroscopy and quantum oscillations. They find that it hosts an “ideal” Kramers nodal line, well isolated at the Fermi level.

  • The authors employ zero-field muon spin relaxation to study time-reversal symmetry breaking (TRSB) in FeSe1−xTex. For x = 0.64 with the highest superconducting transition temperature Tc = 14.5 K, which is known to host a topological surface state and Majorana zero modes within vortices, they find a TRSB superconducting state in the bulk.

  • The authors report that the metallic spin-1/2 chain compound Ti4MnBi2 forms near a quantum critical point with inherent frustration. They identify strong 1D spin and 3D electron coupling that should stimulate the search for materials exhibiting a 1D Kondo effect and heavy fermions.

  • High-pressure synthesis is used to stabilize superconducting (Ba,K)SbO3, whose properties provide a fresh perspective on the origin of superconductivity in these types of materials.

  • High-entropy alloys are interesting as they enable the stabilization of high-symmetry phases, giving rise to unique emerging properties. Here, selenium fluctuations in (Ag,Sn)Se are investigated, revealing their role in promoting superconductivity and stabilizing the cubic rocksalt structure.

  • Ultra-pure materials are essential for exploring intrinsic physics, yet achieving such purity often demands extensive crystal growth optimization. Here, the authors reveal that PtSn4 naturally exhibits extremely low defect levels, confirmed through resistivity measurements and microscopy, establishing it as an ideal platform for studying extreme magnetoresistance and topology.

  • Prediction of new high entropy materials presents a significant challenge. Here, the authors combine experimental and computational methods to search for new high entropy oxides in the tetravalent AO2 family and show why (Ti, Zr, Hf, Sn)2 crystallizes in a α-PbO2 structure.
