The resurgence of interest in Kondo insulators has been driven by two major mysteries: the presence metallic surface states and observation quantum oscillations. To further explore these mysteries, it is crucial to investigate another similar system beyond existing ones, SmB$_6$ YbB$_{12}$. Here, we address this reporting on a insulator, U$_3$Bi$_4$Ni$_3$. Our transport measurements reveal that state emerges below 250 K dominates properties 150 K, which well above temperature scale At low...
Characterizing the low-energy dynamics of quantum materials is crucial to our understanding strongly correlated electronic states. However, extracting universal dynamical features requires resolving correlations at both low energy and momentum. Here, we introduce nitrogen-vacancy (NV) centers in diamond as a novel powerful sensing platform superconducting materials. We demonstrate strengths approach by probing several phenomena high-$T_c$ cuprate Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$ (BSCCO) --...

The tetragonal heavy-fermion superconductor CeRh2As2 (Tc=0.3 K) exhibits an exceptionally high critical field of 14 T for B∥c. It undergoes a field-driven first-order phase transition between superconducting states, potentially transitioning from spin-singlet to spin-triplet superconductivity. To further understand these states and the role magnetism, we probe spin fluctuations in using neutron scattering. We find dynamic (π,π) antiferromagnetic (AFM) correlations with anisotropic...
Kondo-lattice systems are recognized for potentially hosting a variety of rich topological phases. Several pioneering studies have demonstrated significant anomalous Hall and Nernst effects in these systems, attributed to the Berry curvature hybridization bands. In this paper, we investigate UBiTe, ferromagnetic system. Our findings reveal that intrinsic contribution conductivity is closely tied Kondo coherence temperature. Moreover, demonstrate slight shifts Fermi level across three...
