$c=1$ strings as a matrix integral

We study the perturbative S S -matrix of the c=1 c = 1 string and show that it admits a description in terms of a double-scaled (0+0)-dimensional matrix integral based on the spectral curve \mathsf{x}(z) = 2\sqrt{2}\cos(z) 𝗑 ( z ) = 2 2 cos ⁡ ( z ) , \mathsf{y}(z)=\sin(z) 𝗒 ( z )...

The super Virasoro minimal string from 3d supergravity

The super Virasoro minimal string is defined by coupling spacelike and timelike super Liouville theories on the worldsheet. There are four different theories 0A ^± ± and 0B ^± ± depending on discrete choices on the worldsheet. We show that these theories arise naturally from quan...
