Noninteracting fermions with effective mass m_eff(x) ~ |x|^α form a determinantal point process whose large-N scaled kernel near the origin is a sum of two Bessel kernels with different indices rather than standard Airy or single-Bessel forms.
Before proceeding further, we discuss the expressions forx edge and the interparticle distance denoted byW N

Sluggish quantum mechanics of noninteracting fermions with spatially varying effective mass
Noninteracting fermions with effective mass m_eff(x) ~ |x|^α form a determinantal point process whose large-N scaled kernel near the origin is a sum of two Bessel kernels with different indices rather than standard Airy or single-Bessel forms.
