Entanglement Entropy and Cauchy-Hadamard Renormalization

Benoit Estienne, Jiasheng Lin

This note presents a purely geometric construction of the so-called twist-field correlation functions in Conformal Field Theory (CFT), derived from conical singularities. This appr…

Entanglement entropies of an interval for the massless scalar field in the presence of a boundary

Benoit Estienne, Yacine Ikhlef, Andrei Rotaru +1

We study the entanglement entropies of an interval for the massless compact boson either on the half line or on a finite segment, when either Dirichlet or Neumann boundary conditio…

The operator algebra of cyclic orbifolds

Benoit Estienne, Yacine Ikhlef, Andrei Rotaru

We identify the maximal chiral algebra of conformal cyclic orbifolds. In terms of this extended algebra, the orbifold is a rational and diagonal conformal field theory, provided th…

Second level semi-degenerate fields in W3 Toda theory: matrix element and differential equation

Vladimir Belavin, Xiangyu Cao, Benoit Estienne +1

In a recent study we considered W3 Toda 4-point functions that involve matrix elements of a primary field with the highest-weight in the adjoint representation of sl3. We generaliz…

Correlation functions with fusion-channel multiplicity in W3 Toda field theory

Vladimir Belavin, Benoit Estienne, Omar Foda +1

Current studies of WN Toda field theory focus on correlation functions such that the WN highest-weight representations in the fusion channels are multiplicity-free. In this work, w…

Conformal blocks in Virasoro and W theories: duality and the Calogero-Sutherland model

Benoit Estienne, Vincent Pasquier, Raoul Santachiara +1

We study the properties of the conformal blocks of the conformal field theories with Virasoro or W-extended symmetry. When the conformal blocks contain only second-order degenerate…

Relating Jack wavefunctions to WA_{k-1} theories

Benoit Estienne, Raoul Santachiara

The (k,r)-admissible Jack polynomials, recently proposed as many-body wavefunctions for non-Abelian fractional quantum Hall systems, have been conjectured to be related to some cor…

Renormalization group flows for the second parafermionic field theory for even

Benoit Estienne

Extending the results obtained in the case odd, the effect of slightly relevant perturbations of the second parafermionic field theory with the symmetry , for $…

Renormalization group flows for the second parafermionic field theory for N odd

Vladimir S. Dotsenko, Benoit Estienne

Using the renormalization group approach, the Coulomb gas and the coset techniques, the effect of slightly relevant perturbations is studied for the second parafermionic field theo…
