Aspects of Nonrelativistic Strings

Understand

We review recent developments on nonrelativistic string theory.

• In flat spacetime, the theory is defined by a two-dimensional relativistic quantum field theory with nonrelativistic global symmetries acting on the worldsheet fields.
• This theory arises as a self-contained corner of relativistic string theory.
• It has a string spectrum with a Galilean dispersion relation, and a spacetime S-matrix with nonrelativistic symmetry.
