Phase transitions, order by disorder and finite entropy in the Ising antiferromagnetic bilayer honeycomb lattice
F. A. Gómez Albarracín, H. D. Rosales, Pablo Serra
We present an analytical and numerical study of the Ising model on a bilayer honeycomb lattice including interlayer frustration and coupling with an external magnetic field. First,…
Quantum Confinement and Negative Heat Capacity
Pablo Serra, Marcelo Carignano, Fahhad Alharbi +1
Thermodynamics dictates that the specific heat of a system is strictly non-negative. However, in finite classical systems there are well known theoretical and experimental cases wh…
Self-avoiding walks on a bilayer Bethe lattice
Pablo Serra, Jürgen F. Stilck
We propose and study a model of polymer chains in a bilayer. Each chain is confined in one of the layers and polymer bonds on first neighbor edges in different layers interact. We…
Grand canonical and canonical solution of self-avoiding walks with up to three monomers per site on the Bethe lattice
T. J. Oliveira, J. F. Stilck, P. Serra
We solve a model of polymers represented by self-avoiding walks on a lattice which may visit the same site up to three times in the grand-canonical formalism on the Bethe lattice.…
Solution of a model of SAW's with multiple monomers per site on the Husimi lattice
T. J. Oliveira, J. F. Stilck, P. Serra
We solve a model of self-avoiding walks which allows for a site to be visited up to two times by the walk on the Husimi lattice. This model is inspired in the Domb-Joyce model and…
Solution of a model of self-avoiding walks with multiple monomers per site on the Bethe lattice
Pablo Serra, Juergen F. Stilck
We solve a model of self-avoiding walks with up to two monomers per site on the Bethe lattice. This model, inspired on the Domb-Joyce model, was recently proposed to describe the c…
