On gonihedric loops and quantum gravity
D. Espriu, A. Prats
We present an analysis of the gonihedric loop model, a reformulation of the two dimensional gonihedric spin model, using two different techniques. First, the usual regular lattice…

Chiral dynamics from the hadronic string: general formalism
A. A. Andrianov, D. Espriu, A. Prats
QCD at long distances can be described by the chiral Lagrangian. On the other hand there is overwhelming evidence that QCD and all non-abelian theories admit an effective string de…

Dynamics of the two-dimensional gonihedric spin model
D. Espriu, A. Prats
In this paper we study dynamical aspects of the two-dimensional gonihedric spin model using both numerical and analytical methods. This spin model has vanishing microscopic surface…
