Thermal critical dynamics from equilibrium quantum fluctuations
Irénée Frérot, Adam Rançon, Tommaso Roscilde
We show that quantum fluctuations display a singularity at thermal critical points, involving the dynamical exponent. Quantum fluctuations, captured by the quantum variance (I.…
Quench dynamics of quasi-periodic systems exhibiting Rabi oscillations of two-level integrals of motion
Leonardo Benini, Piero Naldesi, Rudolf A. Römer +1
The elusive nature of localized integrals of motion (or l-bits) in disordered quantum systems lies at the core of some of their most prominent features, i.e. emergent integrability…
Spin squeezing from bilinear spin-spin interactions: two simple theorems
Tommaso Roscilde, Fabio Mezzacapo, Tommaso Comparin
We demonstrate two simple theorems about squeezing induced by bilinear spin-spin interactions that conserve spin parity -- including a vast majority of quantum spin models implemen…
Studying the low-entropy Mott transition of bosons in a three-dimensional optical lattice by measuring the full momentum-space density
Gaétan Hercé, Cécile Carcy, Antoine Tenart +4
We report on a combined experimental and theoretical study of the low-entropy Mott transition for interacting bosons trapped in a three-dimensional (3D) cubic lattice -- namely, th…
Robust spin squeezing from the tower of states of -symmetric spin Hamiltonians
Tommaso Comparin, Fabio Mezzacapo, Tommaso Roscilde
Spin squeezing - a central resource for quantum metrology - can be generated via the non-linear, entangling evolution of an initially factorized spin state. Here we show that robus…
Optimal entanglement witnesses: a scalable data-driven approach
Irénée Frérot, Tommaso Roscilde
Multipartite entanglement is the key resource allowing quantum devices to outperform their classical counterparts, and entanglement certification is fundamental to assess any quant…
