Altermagnets simultaneously possess momentum-dependent nonrelativistic spin splitting and zero net magnetization (1-6). Their defining crystalline symmetry connects opposite-spin sublattices in real space and imposes alternating spin polarization on the symmetry-related electronic states in momentum space (1-3). Identi...
Charge density wave (CDW) and superconductivity have long been recognized as competing orders. However, recent achievements establish that the interplay between these two collective electronic phenomena can be more perplexing, with emergent phenomena arising from their cooperation. Here we report a distinctive case of...

Nickelate superconductors, sharing a similar electronic environment with cuprate superconductors, offer a promising platform for unraveling the mechanism of high-temperature superconductivity. However, the realization of superconductivity in these systems has so far been restricted to thin films or bulk samples under h...

Natural van der Waals (vdW) materials offer a fertile ground for exploring stacking-dependent physics analogous to moiré superlattices. In this study, we investigate lightly Se-doped 4Hb-TaS
