Fixed boundary conditions and phase transitions in pure gauge compact QED
M. Baig, H. Fort
We have simulated the pure gauge compact QED with fixed boundary conditions, on lattices from to . We argue that a lattice with this fixed boundary imposition correspon…
Conditional Quantum Walk and Iterated Quantum Games
G. Abal, R. Donangelo, H. Fort
Iterated bipartite quantum games are implemented in terms of the discrete-time quantum walk on the line. Our proposal allows for conditional strategies, as two rational agents make…
On Evolutionary Spatial Heterogeneous Games
H. Fort
How coperation between self-interested individuals evolve is a crucial problem, both in biology and in social sciences, that is far from being well understood. Evolutionary game th…
On the Nature of the Phase Transition Triggered by Vortex-Like Deffects in the 2D Ginzburg-Landau Model
G. Alvarez, H. Fort
The two dimensional lattice Ginzburg-Landau hamiltonian is simulated numerically for different values of the coherence length in units of the lattice spacing , a parameter…
Matter Fields in the Lagrangian Loop Representation: Scalar QED
J. M. Aroca, M. Baig, H. Fort +1
We present the extension of the Lagrangian loop gauge invariant representation in such a way to include matter fields. The partition function of lattice compact U(1)-Higgs model is…
Loop Representation of the Partition Function of Lattice U(1) Gauge Theory
J. M. Aroca, H. Fort
We introduce in a natural and straigthforward way the (Lagrangian) for the partition function of pure compact lattice QED. The corresponding classical latti…
