Generalized Geometry, T-duality, and Renormalization Group Flow
We interpret the physical B-field renormalization group flow in the language of Courant algebroids, clarifying the sense in which this flow is the natural “Ricci flow” for generalized geometry. Next we show that the B-field renormalization group flow preserves T-duality in a natural sense. As corollaries we obtain new long time existence results for the B-field renormalization group flow.
متن کاملHeterotic T-duality and the Renormalization Group
We consider target space duality transformations for heterotic sigma models and strings away from renormalization group fixed points. By imposing certain consistency requirements between the T -duality symmetry and renormalization group flows, the one loop gauge beta function is uniquely determined, without any diagram calculations. Classical T -duality symmetry is a valid quantum symmetry of t...
متن کاملT-duality, quotients and generalized Kähler geometry
In this paper we reopen the discussion of gauging the two-dimensional off-shell (2, 2) supersymmetric sigma models written in terms of semichiral superfields. The associated target space geometry of this particular sigma model is generalized Kähler (or bi-hermitean with two noncommuting complex structures). The gauging of the isometries of the sigma model is now done by coupling the semichiral ...
متن کاملT-duality and Generalized Complex Geometry
We find the explicit T-duality transformation in the phase space formulation of the N = (1, 1) sigma model. We also show that the T-duality transformation is a symplectomorphism and it is an element of O(d, d). Further, we find the explicit T-duality transformation of a generalized complex structure. We also show that the extended supersymmetry of the sigma model is preserved under the T-duality.
متن کاملDuality and Reversal of Renormalization Group Ow
The coupling of a boundary spin operator to the two dimensional Ising model is known to lead to renormalization group ow to a theory with xed or Dirichlet boundary conditions at large distance from the boundary. Using the fact that spin and disorder operators are dual under a Kramers{Wannier or T-duality transformation, we show that coupling a boundary disorder operator results in an RG ow to f...
