Powerful method to evaluate the mass gaps of free-particle quantum critical systems

Francisco C. Alcaraz, José A. Hoyos, Rodrigo A. Pimenta

We present a numerical method for the evaluation of the mass gap, and the low-lying energy gaps, of a large family of free-fermionic and free-parafermionic quantum chains. The meth…

Nonlocal growth processes and conformal invariance

Francisco C. Alcaraz, Vladimir Rittenberg

Up to now the raise and peel model was the single known example of a one-dimensional stochastic process where one can observe conformal invariance. The model has one-parameter. Dep…

Entanglement of excited states in critical spin chians

Miguel Ibanez Berganza, Francisco Castilho Alcaraz, German Sierra

Renyi and von Neumann entropies quantifying the amount of entanglement in ground states of critical spin chains are known to satisfy a universal law which is given by the Conformal…

From conformal invariance to quasistationary states

Francisco C. Alcaraz, Vladimir Rittenberg

In a conformal invariant one-dimensional stochastic model, a certain non-local perturbation takes the system to a new massless phase of a special kind. The ground-state of the syst…

A conformal invariant growth model

Francisco C. Alcaraz, Vladimir Rittenberg

We present a one-parameter extension of the raise and peel one-dimensional growth model. The model is defined in the configuration space of Dyck (RSOS) paths. Tiles from a rarefied…

Shared Information in Stationary States at Criticality

F. C. Alcaraz, V. Rittenberg

We consider bipartitions of one-dimensional extended systems whose probability distribution functions describe stationary states of stochastic models. We define estimators of the s…
