$$ T\overline{T} $$ Deformation of stress-tensor correlators from random geometry

نویسندگان

چکیده

We study stress-tensor correlators in the $T\bar{T}$-deformed conformal field theories two dimensions. Using random geometry approach to $T\bar{T}$ deformation, we develop a geometrical method compute correlators. More specifically, derive deformation Polyakov-Liouville anomaly action and calculate three four-point first-order from deformed action. The results are checked against standard perturbation theory computation further check consistency with operator product expansions of stress tensor. A salient feature is logarithmic correction that absent three-point functions but starts appearing function.

Stress Tensor Correlators in the Schwinger - Keldysh Formalism

We express stress tensor correlators using the Schwinger-Keldysh formalism. The absence of off-diagonal counterterms in this formalism ensures that the +− and −+ correlators are free of primitive divergences. We use dimensional regularization in position space to explicitly check this at one loop order for a massless scalar on a flat space background. We use the same procedure to show that the ...

The Stress Tensor in Quenched Random Systems

The talk describes recent progress in understanding the behaviour of the stress tensor and its correlation functions at a critical point of a generic quenched random system. The topics covered include: (i) the stress tensor in random systems considered as deformed pure systems; (ii) correlators of the stress tensor at a random fixed point: expectations from the replica approach and c-theorem su...

Energy-momentum tensor correlators and spectral functions

We calculate the thermal Euclidean correlators and the spectral functions of the energymomentum tensor for pure gauge theories, including at non-zero spatial momentum, at leading order in perturbation theory. Our goal is to improve the extraction of transport properties from Euclidean correlators that are computable in lattice QCD. Based on our results and the predictions of hydrodynamics for t...
