Giant number-parity effect and scalable spin squeezing in Luttinger liquids
Filippo Caleca, Saverio Bocini, Fabio Mezzacapo +1
Finite-size quantum spin systems can be magnetized by the application of a symmetry-breaking field, but in general their symmetry is expected to be restored once the field is turne…
Tomonaga-Luttinger Liquid Behavior in a Rydberg-encoded Spin Chain
Gabriel Emperauger, Mu Qiao, Cheng Chen +14
Quantum fluctuations can disrupt long-range order in one-dimensional systems, and replace it with the universal paradigm of the Tomonaga-Luttinger liquid (TLL), a critical phase of…
Giant number-parity effect leading to spontaneous symmetry breaking in finite-size quantum spin models
Filippo Caleca, Saverio Bocini, Fabio Mezzacapo +1
Spontaneous symmetry breaking (SSB) occurs when a many-body system governed by a symmetric Hamiltonian, and prepared in a symmetry-broken state by the application of a field coupli…
Non-local quench spectroscopy of fermionic excitations in 1D quantum spin chains
Saverio Bocini, Filippo Caleca, Fabio Mezzacapo +1
The elementary excitations of quantum spin systems have generally the nature of weakly interacting bosonic quasi-particles, generated by local operators acting on the ground state.…
Entanglement entropy of two disjoint intervals and spin structures in interacting chains in and out of equilibrium
Vanja Marić, Saverio Bocini, Maurizio Fagotti
We take the paradigm of interacting spin chains, the Heisenberg spin- XXZ model, as a reference system and consider interacting models that are related to it by Jordan…
No eigenstate of the critical transverse-field Ising chain satisfies the area law
Saverio Bocini, Maurizio Fagotti
We argue that, in a basis common to all one-site shift invariant conserved charges, there is no eigenstate of a noninteracting local spin-1/2 chain Hamiltonian that satisfies the a…
Connected correlations in partitioning protocols: a case study and beyond
Saverio Bocini
The assumption of local relaxation in inhomogeneous quantum quenches allows to compute asymptotically the expectation value of local observables via hydrodynamic arguments known as…
Growing Schrödinger's cat states by local unitary time evolution of product states
Saverio Bocini, Maurizio Fagotti
We envisage many-body systems that can be described by quantum spin-chain Hamiltonians with a trivial separable eigenstate. For generic Hamiltonians, such a state represents a quan…
Measurement catastrophe and ballistic spread of charge density with vanishing current
Lenart Zadnik, Saverio Bocini, Kemal Bidzhiev +1
One of the features of many-body quantum systems with Hilbert-space fragmentation is the existence of stationary states manifesting quantum jamming. It was recently shown that thes…
Non-probabilistic fermionic limit shapes
Saverio Bocini, Jean-Marie Stéphan
We study a translational invariant free fermions model in imaginary time, with nearest neighbor and next-nearest neighbor hopping terms, for a class of inhomogeneous boundary condi…
