A Parafermionic Generalization of the Jaynes Cummings Model
Alessandro Nigro, Marco Gherardi
We introduce a parafermionic version of the Jaynes Cummings Hamiltonian, by coupling Fock parafermions (nilpotent of order ) to a 1D harmonic oscillator, representing the in…
q-deformed Loewner evolution
Marco Gherardi, Alessandro Nigro
The Loewner equation, in its stochastic incarnation introduced by Schramm, is an insightful method for the description of critical random curves and interfaces in two-dimensional s…
Free Field realization of the Algebra for the - system, Integrals of Motion and Characters
Alessandro Nigro
We introduce a free field realization of the central extension of the Lie algebra of difference operators on the circle in terms of the fermionic - system. Th…
Lattice Integrals of Motion of the Ising Model on the Strip
Alessandro Nigro
We consider the 2D critical Ising model on a strip with fixed boundary conditions. It is shown that for a suitable reparametrization of the known Boltzmann weights the transfer mat…
A q-Virasoro Algebra at roots of unity, Free Fermions and Temperley Lieb Hamiltonians
Alessandro Nigro
In this work we introduce a novel q-deformation of the Virasoro algebra expressed in terms of free fermions, we then realize that this algebra, when the deformation parameter is a…
Finite Size Corrections for Dimers
Alessandro Nigro
In this paper we derive the finite size corrections to the energy eigenvalues of the energy for 2D dimers on a square lattice. These finite size corrections, as in the case of Crit…
