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…
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…
