Pressure-enhanced fractional Chern insulators along a magic line in moiré transition metal dichalcogenides
We show that pressure applied to twisted WSe_{2} can enhance the many-body gap and region of stability of a fractional Chern insulator at filling ν=1/3. Our results are based on exact diagonalization of a continuum model, whose pressure dependence is obtained through ab initio methods. We interpret...
