On TT Deformation in Electrodynamic Theories and S-duality


Abstract: The nonlinear electrodynamics theory that couples to an axion field is invariant under the SL(2, R) duality in the Einstein frame. we show that there are the SL(2, R) invariant forms of the energy-momentum tensors of axion-nonlinear electrodynamics theories in the Einstein frame. We investigate the T T? -like flows for non-linear electrodynamic theories in D= 2n dimensional spacetime. We show that this flow equation is compatible with TT? deformation of non-linear Born-Infeld type theories in D =2 and D =4 dimensions. However, our computation discloses that this kind of TT? flow is in conflict with the deformation of Born-Infeld the ...
