Renormalized perturbation theory at large expansion orders

Our formalism permits to easily complement perturbation theory with non-perturbative information, which we illustrate by implementing expansions renormalized by the addition of a gap or the inclusion of Dynamical Mean-Field Theory. Expand abstract.

A framework for geometric field theories and their classification in dimension one

In this paper, we develop a general framework of geometric functorial field theories, meaning that all bordisms in question are endowed with a particular kind of geometric structure. Expand abstract.

Bosonic ghostbusting -- The bosonic ghost vertex algebra admits a logarithmic module category with rigid fusion

The rank 1 bosonic ghost vertex algebra, also known as the $\beta \gamma$ ghosts, symplectic bosons or Weyl vertex algebra is a simple example of a conformal field theory which is neither rational, nor $C_2$-cofinite. Expand abstract.

Time dependence of reflected entropy in conformal field theory

We calculate the time dependence of the reflected entropy of two disconnected regions after a global quench in $(1+1)$-dimensional conformal field theories. Expand abstract.

Dynamical RG and Critical Phenomena in de Sitter Space

Perturbative quantum field theory in de Sitter space is known to give rise a variety of contributions that diverge with time (secular terms). Expand abstract.

Decay of Correlation Rate in the Mean Field Limit of Point Vortices Ensembles

It is a classical result that in such limit correlations functions converge to 1, that is, point vortices decorrelate: we compute the rate at which this convergence takes place by means of Gaussian integration techniques, inspired by the correspondence between the 2-dimensional Coulomb gas and the Sine-Gordon Euclidean field theory....

Density Formalism for Quantum Theory

The new formalism, developed first for the single-particle case, has the advantage of generalizing immediately to quantum field theory and to the description of relativistic phenomena such as particle creation and annihilation. Expand abstract.
