KLT Factorization of Winding String Amplitudes
Jaume Gomis, Ziqi Yan, Matthew Yu
We uncover a Kawai-Lewellen-Tye (KLT)-type factorization of closed string amplitudes into open string amplitudes for closed string states carrying winding and momentum in toroidal…
Symmetries and Anomalies of (1+1)d Theories: 2-groups and Symmetry Fractionalization
Matthew Yu
We investigate the interactions of discrete zero-form and one-form global symmetries in (1+1)d theories. Focus is put on the interactions that the symmetries can have on each other…
T-Duality in Nonrelativistic Open String Theory
Jaume Gomis, Ziqi Yan, Matthew Yu
Nonrelativistic open string theory is defined by a worldsheet theory that produces a Galilean invariant string spectrum and is described at low energies by a nonrelativistic Yang-M…
Background Field Method for Nonlinear Sigma Models in Nonrelativistic String Theory
Ziqi Yan, Matthew Yu
We continue the study of nonrelativistic string theory in background fields. Nonrelativistic string theory is described by a nonlinear sigma model that maps a relativistic worldshe…
