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…
3-phases Confusion Learning
Filippo Caleca, Simone Tibaldi, Elisa Ercolessi
The use of Neural Networks in quantum many-body theory has seen a formidable rise in recent years. Among the many possible applications, one surely is to make use of their pattern…
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.…
The maxcut of the sunrise with different masses in the continuous Minkoskean dimensional regularisation
Filippo Caleca, Ettore Remiddi
We evaluate the maxcut of the two loops sunrise amplitude with three different masses by using the Minkoskean (as opposed to the usual Euclidean) continuous dimension regularisatio…
