Exotic Origins of Tensionless Superstrings

Understand

A new type of tensionless superstring theory, called the Inhomogeneous tensionless superstring, has been recently introduced.

• This is characterised by a residual symmetry algebra on the worldsheet richer in structure than the previously known symmetry algebra related to Homogeneous tensionless superstring.
• In this paper, we investigate theories of tensile superstring that the Inhomogeneous tensionless superstring with manifestly real fermions could arise from.
• We provide two different candidates for these parent tensile theories.
