Segregation in spatially structured cities
Diego Ortega, Javier Rodríguez-Laguna, Elka Korutcheva
Half of the world population resides in cities and urban segregation is becoming a global issue. One of the best known attempts to understand it is the Schelling model, which consi…
Exotic correlation spread in free-fermionic states with initial patterns
Sudipto Singha Roy, Giovanni Ramírez, Silvia N. Santalla +2
We describe a relation between the light-cone velocities after a quantum quench and the internal structure of the initial state, in the particular case of free fermions on a chain…
Entanglement in non-critical inhomogeneous quantum chains
Nadir Samos Sáenz de Buruaga, Silvia N. Santalla, Javier Rodríguez-Laguna +1
We study an inhomogeneous critical Ising chain in a transverse field whose couplings decay exponentially from the center. In the strong inhomogeneity limit we apply Fisher's renorm…
Bulk-edge correspondence in the Haldane phase of the bilinear-biquadratic spin-1 Hamiltonian
Sudipto Singha Roy, Silvia N. Santalla, Javier Rodríguez-Laguna +1
The Haldane phase is the prototype of symmetry protected topological (SPT) phases of spin chain systems. It can be protected by several symmetries having in common the degeneracy o…
First-Passage Percolation under extreme disorder: from bond-percolation to Kardar-Parisi-Zhang universality
Daniel Villarrubia, Iván Álvarez Domenech, Silvia N. Santalla +2
We consider the statistical properties of arrival times and balls on first-passage percolation (FPP) square lattices with strong disorder in the link-times. A previous work sh…
Power Accretion in Social Systems
Silvia N. Santalla, Kostadin Koroutchev, Elka Korutcheva +1
We consider a model of power distribution in a social system where a set of agents play a simple game on a graph: the probability of winning each round is proportional to the agent…
