(Anti-)De Sitter null strings and Carroll-Weyl symmetry

Ulf Lindström, Bo Sundborg

We construct a $d S_{d}$ null string in a novel way by lifting the standard tensionless string to $R^{1, d}$ . Gauging worldsheet scale symmetry introduces terms in the action breaking…

Ricci-flat metrics from gauged linear $σ$ -models without RG flow

Dmitri Bykov, Ondrej Hulik, Ulf Lindström +2

We investigate a class of Ricci-flat Kähler metrics on generalized conifolds constructed via gauged linear sigma models (GLSMs) with indefinite signature. By introducing shadow coo…
