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…
