Extended Data Fig. 4: Calculated superconducting phase diagram of atomically thin 2M-WS2.
From: Spin–orbit–parity coupled superconductivity in atomically thin 2M-WS2
a, b, Theoretically calculated \(B_{C2}^{||}/B_p - T/T_C\) phase found from minimizing the free energy of bilayer 2M-WS2 without (a) and with (b) adding the orbital effect, respectively. The color represents the magnitude of the superconducting gap Δ/Δ0 (The zero-field BCS gap Δ0 = 1.764 kBTC) at different magnetic fields and temperatures. c. The calculated Δ/Δ0 as a function of B||/BP without (red solid line) and with (violet solid line) considering an orbital effect, corresponding to the line cut of (a) and (b) at T = 0.2 TC. Note that the \(B_{C2}^{||}/B_P\) value at which the superconducting gap reaches zero changes very little with and without the orbital effect (\(\lesssim 7{{{\mathrm{\% }}}}\)), which indicates that the reduction of the \(B_{C2}^{||}\) by the weak orbital effect is roughly less than 7%.
