Studying the perturbed Wess–Zumino–Novikov–Witten SU(2)k theory using the truncated conformal spectrum approach

Nuclear Physics B, 2015
We study the SU(2)k Wess–Zumino–Novikov–Witten (WZNW) theory perturbed by the trace of the primary field in the adjoint representation, a theory governing the low-energy behavior of a class of strongly correlated electronic systems.

LeClair-Mussardo series for two-point functions in Integrable QFT

Journal of High Energy Physics, 2018
We develop a well-defined spectral representation for two-point functions in relativistic Integrable QFT in finite density situations, valid for space-like separations.

Gauge field theory for Poincar\'{e}-Weyl group [PDF]

, 2005
On the basis of the general principles of a gauge field theory the gauge theory for the Poincar\'{e}-Weyl group is constructed. It is shown that tetrads are not true gauge fields, but represent functions from true gauge fields: Lorentzian, translational ...

Statistical equilibrium in quantum gravity: Gibbs states in group field theory [PDF]

New Journal of Physics, 2018
Gibbs states are known to play a crucial role in the statistical description of a system with a large number of degrees of freedom. They are expected to be vital also in a quantum gravitational system with many underlying fundamental discrete degrees of ...

Topological Graph Polynomials in Colored Group Field Theory [PDF]

, 2009
In this paper we analyze the open Feynman graphs of the Colored Group Field Theory introduced in [arXiv:0907.2582]. We define the boundary graph $\cG_{\partial}$ of an open graph $\cG$ and prove it is a cellular complex.

Limiting curvature mimetic gravity for group field theory condensates [PDF]

Physical Review D, 2018
Nonsingular bouncing cosmologies are realized in limiting curvature mimetic gravity by means of a multi-valued potential $f(\Box\phi)$ depending on the d'Alembertian of a scalar field $\phi$.

Holographic Entanglement in Group Field Theory

Universe, 2019
This work is meant as a review summary of a series of recent results concerning the derivation of a holographic entanglement entropy formula for generic open spin network states in the group field theory (GFT) approach to quantum gravity. The statistical

Composite operators near the boundary

Journal of High Energy Physics, 2020
We use renormalization group methods to study composite operators existing at a boundary of an interacting conformal field theory. In particular we relate the data on boundary operators to short-distance (near-boundary) divergences of bulk two-point ...

Group field theory for quantum gravity minimally coupled to a scalar field [PDF]

, 2017
We construct a group field theory model for quantum gravity minimally coupled to relativistic scalar fields, defining as well a corresponding discrete gravity path integral (and, implicitly, a coupled spin foam model) in its Feynman expansion.

Renormalization group and nonequilibrium action in stochastic field theory [PDF]

, 2002
We investigate the renormalization group approach to nonequilibrium field theory. We show that it is possible to derive nontrivial renormalization group flow from iterative coarse graining of a closed-time-path action.
