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…
Emerging Non-Hermitian Topology in a Chiral Driven-Dissipative Bose-Hubbard Model
Laszlo Rassaert, Tomás Ramos, Tommaso Roscilde +1
We introduce a driven-dissipative Bose-Hubbard chain describing coupled lossy photonic modes, in which time-reversal symmetry is broken by a coherent drive with a uniform phase gra…
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.…
Symmetry: a fundamental resource for quantum coherence and metrology
Irénée Frérot, Tommaso Roscilde
We introduce a new paradigm for the preparation of deeply entangled states useful for quantum metrology. We show that when the quantum state is an eigenstate of an operator , ob…
Scalable spin squeezing from critical slowing down in short-range interacting systems
Tommaso Roscilde, Filippo Caleca, Adriano Angelone +1
Long-range spin-spin interactions are known to generate non-equilibrium dynamics which can squeeze the collective spin of a quantum spin ensemble in a scalable manner, leading to s…
Measuring bipartite spin correlations of lattice-trapped dipolar atoms
Youssef Aziz Alaoui, Sean R. Muleady, Edwin Chaparro +5
We demonstrate a bipartition technique using a super-lattice architecture to access correlations between alternating planes of a mesoscopic array of spin-3 chromium atoms trapped i…
