Correlation functions in conformal Toda field theory I [PDF]

, 2007
Two-dimensional sl(n) quantum Toda field theory on a sphere is considered. This theory provides an important example of conformal field theory with higher spin symmetry.

Density matrix embedding: a simple alternative to dynamical mean-field theory. [PDF]

Physical Review Letters, 2012
We introduce density matrix embedding theory (DMET), a quantum embedding theory for computing frequency-independent quantities, such as ground-state properties, of infinite systems.

Comments on the quantum field theory of the Coulomb gas formalism

Journal of High Energy Physics, 2021
The holomorphic Coulomb gas formalism, as developed by Feigin-Fuchs, Dotsenko-Fateev and Felder, is a set of rules for computing minimal model observables using free field techniques. We attempt to derive and clarify these rules using standard techniques

Pion spectral properties above the chiral crossover of QCD

Journal of High Energy Physics, 2022
Spectral functions encode a wealth of information about the dynamics of any given system, and the determination of their non-perturbative characteristics is a long-standing problem in quantum field theory.

From the sine-Gordon field theory to the Kardar-Parisi-Zhang growth equation [PDF]

, 2014
We unveil a remarkable connection between the sine-Gordon quantum field theory and the Kardar-Parisi-Zhang (KPZ) growth equation. We find that the non-relativistic limit of the two-point correlation function of the sine-Gordon theory is related to the ...

Symplectic quantization: numerical results for the Feynman propagator on a 1+1 lattice and the theoretical relation with quantum field theory

Journal of High Energy Physics
We present here the first lattice simulation of symplectic quantization, a new functional approach to quantum field theory which allows to define an algorithm to numerically sample the quantum fluctuations of fields directly in Minkowski space-time, at ...

Coherence effects in disordered geometries with a field-theory dual

Journal of High Energy Physics, 2018
We investigate the holographic dual of a probe scalar in an asymptotically Anti-de-Sitter (AdS) disordered background which is an exact solution of Einstein’s equations in three bulk dimensions. Unlike other approaches to model disorder in holography, we
