A mass-independent conformal quantum cloak

An obstacle to constructing a quantum cloak with Riding Gear the transformation design method for steering a matter wave is the device involving the anisotropic modulation of the particle mass.It is the purpose of this paper to show that a narrow-acceptance-angle quantum cloak generated by a kind of conformal mapping could be mass-independent.This
