Two branches of bistable temporal cavity solitons are found in models of quantum interference in microresonators with a Λ three-level medium in the anomalous dispersion regime. The cavity solitons are due to the locking of moving domain walls. We identify two distinct Maxwell points on opposite sides of the cavity resonance where domain walls are stationary and two distinct temporal cavity solitons, one narrow and with a high peak intensity, the other broader and with a lower peak intensity, coexist over wide parameter ranges and without the need of secondary cavity resonances. Localized structures combining the two soliton branches oscillate on timescales of tens of cavity round trips. Frequency combs generated by combinations of different types of multistable temporal cavity solitons lead to enhanced bandwidths and their control.
