The spontaneous Hall effect (SHE), observed as a finite zero-field transverse signal, occurs in both conventional and unconventional superconductors, appearing as a peak near the superconducting transition temperature. The origin of SHE is debated, with proposed explanations ranging from intrinsic mechanisms, such as spontaneous symmetry...

The key role played by hydrogen (H) in the near-to-room temperature superconductivity of hydrides at megabar pressures suggests that H doping could produce similar effects in materials at ambient pressure. Here the authors show that ionic gate-driven H intercalation in the layered compound TiSe2 induces a superconducting phase with features...
