Entanglement evolution from entangled multipodal states
Konstantinos Chalas, Pasquale Calabrese, Colin Rylands
In a periodic lattice system an entangled antipodal pair state, otherwise known as a crosscap state, is a simple two site product state in which spins at antipodal sites are prepar…
Quench dynamics of entanglement entropy under projective charge measurements: the free fermion case
Riccardo Travaglino, Colin Rylands, Pasquale Calabrese
We consider the effect of projective measurements on the quench dynamics of the bipartite entanglement entropy in one dimensional free fermionic systems. In our protocol, we consid…
A simpler probe of the quantum Mpemba effect in closed systems
Filiberto Ares, Colin Rylands, Pasquale Calabrese
We study the local relaxation of closed quantum systems through the relative entropy between the reduced density matrix and its long time limit. We show, using analytic arguments c…
Quench dynamics of negativity Hamiltonians
Riccardo Travaglino, Colin Rylands, Pasquale Calabrese
In this paper, we investigate the quench dynamics of the negativity and fermionic negativity Hamiltonians in free fermionic systems. We do this by generalizing a recently developed…
Emergent boundary supersymmetry in a one dimensional superconductor
Parameshwar R. Pasnoori, Patrick Azaria, Colin Rylands +1
The interplay between bulk properties and boundary conditions in one-dimensional quantum systems, gives rise to many intriguing phenomena. These include the emergence of zero energ…
