Avalanches in an extended Schelling model: an explanation of urban gentrification
Diego Ortega, Javier Rodríguez-Laguna, Elka Korutcheva
In this work we characterize sudden increases in the land price of certain urban areas, a phenomenon causing gentrification, via an extended Schelling model. An initial price rise…
Optimizing the spatial spread of a quantum walk
Gonzalo Martín-Vázquez, Javier Rodríguez-Laguna
We devise a protocol to build 1D time-dependent quantum walks in 1D maximizing the spatial spread throughout the procedure. We allow only one of the physical parameters of the coin…
Casimir forces on deformed fermionic chains
Begoña Mula, Silvia N. Santalla, Javier Rodríguez-Laguna
We characterize the Casimir forces for the Dirac vacuum on free-fermionic chains with smoothly varying hopping amplitudes, which correspond to (1+1)D curved spacetimes with a stati…
Random walkers on a deformable medium
Carlos Lajusticia-Costan, Silvia N. Santalla, Javier Rodríguez-Laguna +1
We consider random walkers that deform the medium as they move, enabling a faster motion in regions which have been recently visited. This induces an effective attraction between w…
