	abstract = {In two-dimensional (2D) electron systems, Wigner crystals (WC) and fractional quantum Hall effect (FQHE) liquids are competing ground states under low temperatures\&nbsp;(T)\&nbsp;and high magnetic fields\&nbsp;(B). Here we report differential conductivity results demonstrating the reentrant insulating phase around\&nbsp;ν=1/5 in a 2D hole system in AlGaAs/GaAs quantum wells and unexpected features in the solid-liquid phase transition between WC and FQHE liquids in ultrahigh magnetic fields up to 45 T. Remarkably, the electric field\&nbsp;(E)\&nbsp;plays an equivalent role as the temperature does in our phase diagram. From the\&nbsp;E-T\&nbsp;{\textquotedblleft}duality{\textquotedblright} analysis, a characteristic length of 450 nm is derived, which can be understood as the phase-coherent domain size of WC. Moreover, evidence shows that with weak disorder the insulating phase and composite fermion liquid could be coexisting around\&nbsp;ν=\&nbsp;1/5, pointing to the possibility that the insulating phase is the four flux quantum Wigner crystal, as proposed by theories.},
