Fig. 4

Pressure evolution of various quantities. a The temperature dependence of σsc(T), normalized to its value for the lowest applied pressure, under various applied pressures. The inset illustrates the weak positive pressure dependence of σsc. b The temperature dependence of the diamagnetic shift ΔBdia = μ0(Hint,SC − Hint,NS), recorded for various hydrostatic pressures. c Pressure dependence of the superconducting transition temperature Tc, the zero-temperature value of the superconducting gap Δ and the ratio 2Δ/KBTc for 2M-WS2. The error bars represent the s.d. of the fit parameters. Band structure in the presence of spin-orbit coupling for p = 0 GPa d, 1.3 GPa e and 1.9 GPa f. Red color corresponds to d orbitals of W atoms, while the blue color indicates the p orbitals of S atoms
