Entanglement Halos
Nadir Samos Sáenz de Buruaga, Silvia N. Santalla, Germán Sierra +1
We introduce the concept of entanglement halos, a set of strongly entangled distant sites within the ground state of a quantum many-body system. Such halos emerge in star-like syst…
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…
Entanglement links and the quasiparticle picture
Silvia N. Santalla, Giovanni Ramírez, Sudipto Singha Roy +2
The time evolution of a quantum state with short-range correlations after a quench to a one-dimensional critical Hamiltonian can be understood using the quasi-particle picture, whi…
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…
