An update on supersphere non linear sigma model on the lattice
Ilaria Costa, Valentina Forini, Agostino Patella +1
We consider the discretized version of the sigma-model with supersphere target space and present a preliminary numerical study of bosonic and fermioni…
Supersphere non-linear sigma model on the lattice
Ilaria Costa, Valentina Forini, Ben Hoare +3
Two-dimensional non-linear sigma models are exactly solvable theories and have many applications, from statistical mechanics to their use as QCD toy models. We consider a su…
Holography on the lattice: the string worldsheet perspective
Gabriel Bliard, Ilaria Costa, Valentina Forini
We review the study, on the lattice, of the Green-Schwarz gauge-fixed string action describing worldsheet fluctuations about the minimal surface holographically dual to the null cu…
Lattice perturbation theory for the null cusp string
Gabriel Bliard, Ilaria Costa, Valentina Forini +1
We reconsider the problem of discretising the worldsheet for the gauge-fixed Green-Schwarz superstring on a null cusp background, and present a setup which fully preserves its glob…
-invariant phase of the tensor model
Dario Benedetti, Ilaria Costa
We study classical and quantum (at large-) field equations of bosonic tensor models with quartic interactions and symmetry. Among various possible patterns of spontaneo…
