The fermionic DGFF and its scaling limit logCFT
David Adame-Carrillo, Wioletta M. Ruszel
In this paper, we identify the scaling limit of the fermionic discrete Gaussian free field (fDGFF) as a logarithmic conformal field theory (CFT) in two dimensions. We first establi…
Symplectic fermions in general domains
David Adame-Carrillo
We review the basic features of a logarithmic conformal field theory that arise in the context of the scaling limit of lattice models. The theory of interest is the symplectic ferm…
Fock space of local fields of the discrete GFF and its scaling limit bosonic CFT
David Adame-Carrillo, Delara Behzad, Kalle Kytölä
To connect conformal field theories (CFT) to probabilistic lattice models, recent works [HKV22, Ada23] have introduced a novel definition of local fields of the lattice models. Loc…
Discrete symplectic fermions on double dimers and their Virasoro representation
David Adame-Carrillo
A discrete version of the Conformal Field Theory of symplectic fermions is introduced and discussed. Specifically, discrete symplectic fermions are realised as holomorphic observab…
The second-order problem for -presymplectic Lagrangian field theories. Application to the Einstein--Palatini model
David Adame-Carrillo, Jordi Gaset, Narciso Román-Roy
In general, the system of nd-order partial differential equations made of the Euler-Lagrange equations of classical field theories are not compatible for singular Lagrangians. T…
