Long term behavior of the stirred vacuum on a Dirac chain: geometry blur and the random Slater ensemble
José Vinaixa, Begoña Mula, Alfredo Deaño +2
We characterize the long-term state of the 1D Dirac vacuum stirred by an impenetrable object, modeled as the ground state of a finite free-fermionic chain dynamically perturbed by…
Depletion in fermionic chains with inhomogeneous hoppings
Begoña Mula, Nadir Samos Sáenz de Buruaga, Germán Sierra +2
The ground state of a free-fermionic chain with inhomogeneous hoppings at half-filling can be mapped into the Dirac vacuum on a static curved space-time, which presents exactly hom…
Ergotropy and entanglement in critical spin chains
Begoña Mula, Eva M. Fernández, José E. Alvarellos +4
A subsystem of an entangled ground state is in a mixed state. Thus, if we isolate this subsystem from its surroundings we may be able to extract work applying unitary transformatio…
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…
