Entanglement transition in a cluster spin chain coupled with free spins
Kevissen Sellapillay, Laurent Raymond, Alberto D. Verga
We investigate the entanglement of a ladder of spins formed by two sublattices, a ''cluster'' chain and the ''environment'', consisting of independent spins, both coupled by an exc…
Entanglement dynamics and phase transitions of the Floquet cluster spin chain
Alberto D. Verga
Cluster states were introduced in the context of measurement based quantum computing. In one dimension, the cluster Hamiltonian possesses topologically protected states. We investi…
Entanglement dynamics and ergodicity breaking in a quantum cellular automaton
Kevissen Sellapillay, Alberto Verga, Giuseppe Di Molfetta
Ergodicity breaking is observed in the blockade regime of Rydberg atoms arrays, in the form of low entanglement eigenstates known as scars, which fail to thermalize. The signature…
Quantum walk on a graph of spins: magnetism and entanglement
Kevissen Sellapillay, Alberto D. Verga
We introduce a model of a quantum walk on a graph in which a particle jumps between neighboring nodes and interacts with independent spins sitting on the edges. Entanglement propag…
Thermal state entanglement entropy on a quantum graph
Alberto D. Verga, Ricardo Gabriel Elias
A particle jumps between the nodes of a graph interacting with local spins. We show that the entanglement entropy of the particle with the spin network is related to the length of…
Interacting quantum walk on a graph
Alberto D. Verga
We introduce an elementary quantum system consisting of a set of spins on a graph and a particle hopping between its nodes. The quantum state is build sequentially, applying a unit…
