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…
