Magnetic-field-tunable commensurate multi-q charge orders on UTe2 (011) surface

This study utilizes scanning tunneling microscopy to reveal that the UTe2 (011) surface hosts a family of magnetic-field-tunable, commensurate multi-q charge orders that are distinct from bulk superconductivity and inconsistent with Fermi surface nesting or pair-density-wave mechanisms, suggesting instead a surface parent spin order.

Scanning tunneling microscopy study of helimagnetic monolayer CrBr2 on s-wave superconductor NbSe2: a topologically trivial system due to weak interfacial coupling

This study demonstrates that monolayer helimagnetic CrBr2 grown on an s-wave NbSe2 superconductor forms a topologically trivial system due to weak interfacial coupling, which prevents the induction of proximity superconductivity and the emergence of intrinsic topological edge states.

Distinguishing impurity-induced bound states from Majorana-like zero-energy peaks in strained CsCa2Fe4As4F2 by scanning tunneling microscopy

This study utilizes scanning tunneling microscopy under local strain to demonstrate that while CsCa2Fe4F2 exhibits zero-energy conductance peaks on specific defects that mimic Majorana zero modes, these features actually originate from nearly degenerate Yu-Shiba-Rusinov states, thereby clarifying the material's sign-changing multiband superconductivity and establishing robust methods to distinguish impurity-induced states from topological signatures.

Correlated charge order intertwined with time-reversal symmetry-breaking nodal superconductivity in the dual flat band kagome superconductor CeRu3_{3}Si2_{2}

This study identifies CeRu3_{3}Si2_{2} as a unique kagome superconductor where intertwined Ru dd- and Ce ff-electron flat bands drive a complex hierarchy of charge orders and establish a direct correlation between normal-state time-reversal symmetry breaking and intrinsic nodal superconductivity.

Unified pressure and field response across distinct charge-order regimes in Ti-doped CsV3_3Sb5_5

This muon spin rotation study of Ti-doped CsV3_3Sb5_5 reveals that despite distinct charge-order regimes (long-range vs. short-range) at different doping levels, the material exhibits remarkably similar superconducting responses under pressure, suggesting that the competition between superconductivity and charge order occurs on a local scale independent of long-range charge coherence.

Electronic structure of higher-order layered palladates: Lan+1_{n+1}Pdn_{n}O2n+1_{2n+1} (n=4−7)(n = 4-7)

This study uses *ab initio* calculations to predict that higher-order layered palladates (Lan+1_{n+1}Pdn_{n}O2n+1_{2n+1} for n=4−7n=4-7), though not yet synthesized, possess electronic properties such as larger bandwidths and enhanced p−dp-d hybridization that make them promising, cuprate-like candidates for unconventional superconductivity.

Effect of pressure on the superconducting properties of Au substituted PdTe2_2 with the CdI2_2-type structure

This study investigates the pressure-dependent structural and superconducting properties of Au-substituted PdTe2_2 (AuxPd1-xTe2_2), revealing that the CdI2_2-type structure remains stable up to 8 GPa while the critical temperature exhibits composition-dependent behavior, including shallow maxima for higher Au concentrations, without significant changes to the overall superconducting phase diagram.

Ferromagnetic resonance modulation in topological materials with bulk--boundary coexistence

This paper extends ferromagnetic resonance (FMR) modulation theory to topological materials with coexisting bulk and boundary states, applying it to a dd-wave superconductor to reveal distinct excitation peaks and temperature-dependent decay behaviors that demonstrate the comparable contributions of both states to the FMR response.
